positive space in photography: a guide

As a photographer, you may have heard of negative space, which refers to the more subtle areas surrounding the main subject in a photograph. However, positive space, the populated or focal point of an image, is a term that tends to fly under the radar.

In this article, we’ll take a look at positive space in composition and how you can use it to improve your photos.

What is positive space in photography?

Positive space refers to the subject matter or areas of peak interest in a photograph. It’s the key component of almost every great photo.

That said, like all compositional elements in photography, positive space is influenced by other aspects of a photo. Perhaps one of the most significant of these aspects is negative space – positive space is often sculpted by negative space and vice versa. You see, when photographing a clear subject, there is usually “occupied” or positive subject matter contrasted with negative elements that are not key focal points. Therefore, when discussing positive space, it’s hard not to mention the role of negative space, too.

While positive space may constitute the main show, negative space serves as the stage. And although the word negative seems to imply a lack of content, the term doesn’t just refer to areas completely devoid of subject matter. In fact, negative space only has to be visually quieter, less populated, more subtle, or restful compared to the main subject.

A brief history of positive space

Positive space – and the interaction of positive and negative space – has been used in art throughout history. Painters, sculptors, architects, potters; all have balanced positive and negative dynamics to allow for tactical areas of visual rest, rhythm, focus, activity, atmosphere, etc.

For example, negative space in traditional Japanese art styles is often embraced to accentuate or balance the weight of the expressive and spontaneous brushstrokes that constitute positive subject matter.

Another example is Edgar Degas’s careful use of negative space in his scenes depicting ballet dancers. The negative space imbues the photos with a greater sense of movement, context, and contrast, creating interesting juxtapositions and framing detail.

With the invention of photography, the artistic possibilities of positive and negative space expanded to the photographic image. From Anna Atkins, Henri Cartier-Bresson, Dorothea Lange, and Robert Frank to Diane Arbus, Hiroshi Sugimoto, Steve McCurry, and Didier Massard, photographers have used negative space to support key (positive) focal points.

Why is positive space important?

Positive space matters because it can steer the narrative of an image or draw a viewer’s eye. Without positive space, negative space often looks directionless. In turn, a photograph lacking negative space may seem crowded or overwhelming.

Positive space creates momentum, narrative, and visual climax. Negative space can provide context, emphasis, isolation, and breathing room, funneling the viewer’s eye toward positive space and allowing the focal point to flourish.

Working with positive space: the basics

There are many ways to approach photographing positive space. Here’s what I recommend to get started:

  1. First, identify the positive areas of the scene – the elements of the composition that immediately stand out.
  2. Next, evaluate the negative space (you can use the viewfinder or your LCD for this). What does the negative space do? Does it uphold the positive space? Does it add context? Depth? Atmosphere? Narrative? Beauty?
  3. Finally, consider the technical aspects of your photo, and how they might affect positive and negative space. For example, adjusting the aperture will create a shallow or deep depth of field, where a shallower depth of field will often create more negative space.

These basic considerations will help you improve your use of positive space.

Advanced tips and techniques for working with positive space

If you want to take your compositions to the next level, here are a few tips and tricks to help capitalize on positive space:

Tip 1: Apply compositional techniques

Positive space is a fundamental part of photographic composition, but it doesn’t exist in isolation. It can work alongside other compositional techniques, such as leading lines, depth of field, framing, symmetry, and perspective, to create beautiful photos.

So the next time you’re out with your camera, think about positive space. And also think about how you can use positive space in conjunction with composition principles to get the most impactful results.

Tip 2: Be mindful of both negative and positive space

The key to striking a successful positive/negative balance (or intentional imbalance) often lies in awareness. When composing a photograph, make sure you carefully check the negative space that surrounds a positive space, and ask yourself whether it works as it is – or whether it needs to be modified.

(A quick visual scan through the viewfinder or on the digital screen is a small action that can save time and many wasted shots!)

Furthermore, when framing a subject, running through a quick checklist can be helpful. Ask yourself: What is the negative space contributing? What is the positive space contributing? Does the positive space benefit from the negative regions that surround it?

Briefly pausing to consider the positive/negative dynamics in a photograph can increase the chances of capturing a successful image.

Tip 3: Use your camera settings

Positive space can hinge on negative space that occurs naturally (i.e., the sky, shadows, etc.), or on negative space that is deliberately created through camera settings.

For example, in a busy urban environment, a slow shutter speed can blur the flow of traffic to create negative space (and this will, in turn, emphasize static subjects like buildings and sculptures that constitute positive areas of interest).

ICM (intentional camera movement) can sometimes create blurry and abstract negative areas that highlight positive focal points. Selective focus can emphasize or deemphasize visually positive areas, and by adjusting the aperture settings, you can blur the background and/or foreground surrounding a positive subject. Zooming in or out in-camera or cropping with post-production can also manipulate the dynamics of positive and negative space.

In other words:

If you want more negative space, you can create it yourself! Just tweak your camera settings to achieve the effect you’re after.

Tip 4: Know your narrative

Like all compositional tools, positive space can evoke emotions and tell stories. By determining your narrative in advance, you can use positive and negative space to create an impactful, coherent image.

For example, a smaller positive subject set within a large amount of negative space can evoke a sense of scale, isolation, simplicity, grandiosity, and distance. Negative space in the form of a bold, dark vignette can frame a positive subject for added impact. An image with predominantly positive space can generate immediacy and energy. Evenly distributed positive and negative space can lend to the impression of harmony and balance.

(The list goes on!)

Tip 5: Experiment!

Any positive (and negative) space bends to an endless amount of compositional variables. Experimenting with creative techniques, subjects, and conditions broadens the creative potential of any positive subject.

And although the term “negative” suggests “nothingness,” negative space, as we have seen, is just as versatile and important as its positive counterpart.

So while experimenting with positive space through the mindful manipulation of negative space can be a balancing act, gaining a good grasp on both forms of space will result in the best photos overall.

A guide to positive space: conclusion

Positive space is a critical part of photographic composition. While the discussion of negative space is more common, positive space is the driving force behind countless photographic images.

Consciously working with positive space encourages a greater connection with the subject matter, and it’ll also help you create better compositions.

Now over to you:

This photograph illustrates how quickly the International Space Station orbits Earth

15 Jun

The International Space Station (ISS) moves fast. Very fast. The modular space station has an orbital speed of 7.66 kilometers per second, which is roughly 17,100 mph. It takes the ISS a mere 92.68 minutes to orbit Earth, meaning it goes around Earth nearly 16 times per day. It’s hard to conceptualize that amount of speed, but French astronaut Thomas Pesquet is aboard the ISS now and wanted to help those of us on terra firma understand the speed at which the ISS moves.

Pesquet has been experimenting with different photographic techniques to show the ISS’s speed. He recently shared an image shot with a 30-second exposure that shows ISS stationary in the frame while the Earth’s surface streaks behind in the background.

During the 30 second exposure, the ISS traveled about 235km. Despite the speed of the space station, Pesquet says that the crew doesn’t have the impression of moving that quickly due to the orbital path’s distance from Earth. The ISS perigee altitude is 418km (259.7mi) and its apogee altitude is 422km (262.2mi).

With the ISS orbiting Earth so many times during the day, there are numerous opportunities to spot the station as it orbits Earth. NASA has set up a dedicated alert system (https://spotthestation.nasa.gov) to let you know when the ISS is passing overhead. You can view the ISS with the naked eye, no need for a telescope.

Pesquet is very active aboard the ISS and regularly posts new photos on Twitter. You can also stay to date with all the activities on the ISS on Twitter. NASA regularly posts videos from the ISS on YouTube.

The Rule of Space in Photography: A Comprehensive Guide (+ Examples)

The post The Rule of Space in Photography: A Comprehensive Guide (+ Examples) appeared first on Digital Photography School. It was authored by Megan Kennedy.

rule of space in photography: a comprehensive guide (+ examples)

In this article, I’m going to answer all your questions about the rule of space in photography:

What it is. How it works. And how you can use it for amazing results.

Specifically, by applying the rule of space to photography, you can embrace the quieter moments in visual imagery – and you can amplify the impact of your subject by balancing positive and negative compositional elements.

Let’s dive right in.

What is the rule of space in photography?

The rule of space in photography is a method of incorporating visual absence to give a subject room to breathe.

Although the rule of space is more like a guide than a rigid rule, it is a handy compositional device. It’s a great way to add a sense of vastness, depth, and/or motion to a photograph.

Why is the rule of space important?

To understand the rule of space, we first need to take a brief look at positive and negative space.

Photographers use the terms positive space and negative space to contrast impactful and more subtle areas in a photograph.

Generally, positive space refers to specific subjects that command a viewer’s attention. Negative space, on the other hand, is less visually demanding and provides a frame for the main event in an image.

For example, in the image below, the clouds represent positive space, whereas the sky and dark shadows create the negative space that frames the main subject:

rule of space in photography clouds

So where does the rule of space in photography fit in?

In general terms, the rule of space governs the use of negative space within an image. By understanding the nature of the rule of space, a photographer can harness the intent of a subject, as well as add depth and perspective to the image.

The rule of space is important because it aids a photographer in articulating the energy of a photograph – and it guides the viewer’s eye by sculpting key visual events and affording the subject more room to move.

Working with the rule of space: the basics

To work with the rule of space in photography, first consider the behavior of your subject.

Ask yourself: What is the subject doing? Is it moving or stationary? How does it occupy space?

At the same time, visualize what you want to convey in the photograph. Is it movement? Perspective? Depth? Narrative?

The nature and behavior of your subject plus your intent should together determine how you apply the rule of space.

Perspective

One of the main ways the rule of space can impact a photograph is through perspective. Abundant space around a subject can make the subject appear smaller or larger depending on the camera angle.

For example, a subject photographed from a high angle, surrounded with minimal detail, can seem smaller and more immersed in negative space:

Conveying momentum

The rule of space in photography can help you create the impression of movement.

To convey action, the rule suggests that space should be left either in front of or behind the subject (or both).

For example, if a subject is moving across a scene, you can aim to capture both the subject and the negative space surrounding the subject. The extra space conveys the subject’s movement, adding the momentum a tight crop may lack.

Allowing a subject room to move adds momentum.

Adding depth

The rule of space in photography is not limited to highly active subjects; it works for stationary subject matter, too!

For example, in portraiture, your composition can be governed by pairing the gaze or gesticulations of the subject with negative space. A subject’s gaze naturally directs our attention – we want to see what the subject sees.

But when a gaze is met by negative space, the viewer’s eye will often naturally return to the original source of the gaze. The rule of space provides an organic way of adding depth and directing viewer attention.

You can also use the rule of space with non-human/animal subject matter – based on their movement, perceived gesticulations, and extensions. By following the momentum, composition, or behavior of a non-human subject, you’ll find ideal placements for negative space.

In the example below, I surrounded several blossoms with negative space; this additional room suggests growth and depth. It also highlights the detail in the individual florets.

Leaving extra room around specific flower heads to articulate their elemental composition is one way to emphasize non-human subjects through the rule of space.

Rule of space challenges

The process of applying the rule of space to photographs is not that difficult in itself. However, a tendency to cram each image with as much visual information as possible can get in the way of exploring negative space.

Instead, deliberately and mindfully take a minimalist approach. You can also zoom out or physically take a few steps back from a subject to refocus on the rule of space.

Tips and techniques for working with the rule of space

Here are a few tips for working with the rule of space:

Tip 1: Use other compositional rules, too

Applying the rule of space to your photography doesn’t have to come at the cost of other compositional rules.

In fact, combining compositional tenets with the rule of space in photography can increase the chances of creating a successful photograph.

Compositional rules such as the rule of thirds, leading lines, depth of field, and repetition can all be used in conjunction with the rule of space to create engaging imagery.

Tip 2: Let it breathe

The rule of space is all about giving a subject or a scene room to breathe.

So step back, zoom out, or even try a wider lens; that way, you can add a sense of spaciousness to your photos.

Tip 3: Experiment with different camera settings

Your choice of camera settings can help follow the rule of space more effectively.

For instance, you might use a shallow depth of field to surround a subject with negative space. You could also try using a slow shutter speed and panning your camera while leaving space before or after a subject to amplify movement.

The rule of space in photography: conclusion

The rule of space aims to create a mindful harmony of positive and negative space.

And by applying this rule, you can emphasize and frame positive subject matter while generating an evocative balance of weight and weightlessness within an image.

So the next time you’re out with your camera, remember the rule of space – and do what you can to apply it in your images!

Rule of space FAQs

What is the rule of space?

In visual art, the rule of space guides your inclusion of negative space within an image.

What is negative space?

Generally, negative space refers to areas in a photograph that are not occupied by the main subject matter. Often, negative space serves as a frame to emphasize the key subjects in an image.

How do photographers use the rule of space in composition?

The rule encourages photographers to make use of negative space. There are many ways to do this. You can focus on coupling subjects with negative space by selecting minimalist backdrops, or you can pair the gaze of a portrait subject with additional negative space.

Who are some photographers that use the rule of space?

There are countless photographers who make use of the rule of space. For example, photographers Martin Parr and Helen Levitt made striking use of the rule, as well as Hiroshi Sugimoto, Michael Kenna, and Eric Kim.

When can I break the rule of space in photography?

Photography is all about developing personal creative instincts and approaches. That’s why compositional rules can be broken. The rule of space in photography is simply a guide – so if an image looks better without extra space, then go with your instincts. And if you aren’t sure, try taking a series of photos with different spatial approaches and analyze the results.

Documenting humanity’s journey into space: Over 2,400 iconic space images are up for auction

13 Nov
Lead image: ‘The ‘Blue Marble’, the first human-taken photograph of the Earth fully illuminated, December 7-19, 1972, Harrison Schmitt [Apollo 17]. Estimate: £15,000-31,500. Offered in Voyage to Another World: The Victor Martin-Malburet Photograph Collection, November 6-19, 2020, Online’ Caption and image courtesy of CHRISTIE’S IMAGES LTD. 2020

Christie’s has placed up for auction a massive collection of images, many of which document the American space program from the 1940s through the 1970s. The collection, ‘Voyage to Another World: The Victor-Martin Malburet Photograph Collection,’ includes 700 lots comprising more than 2,400 separate items.

Bidding began on November 6 and continues until November 19 for lots 1-325 and November 20 for the remaining lots. Christie’s states that the collection traces ‘the artistic heritage of the Apollo Missions and Golden Age of space exploration.’

‘The first photograph of man in space [Large Format], Ed White’s first American EVA over Hawaii, June 3-7, 1965, James McDivitt [Gemini IV]. Estimate: £6,000-8,000. Offered in Voyage to Another World: The Victor Martin-Malburet Photograph Collection, November 6-19, 2020, Online’ Caption and image courtesy of CHRISTIE’S IMAGES LTD. 2020

Martin-Malburet has built this collection over the last 15 years. He has been interested in images captured in space since he accompanied his father to an auction. ‘It was a sale of astronautical artifacts,’ says Martin-Malburet, ‘We bought various things, including an autograph of Yuri Gagarin. But the item that impressed me most was a photograph, the famous shot of Buzz Aldrin on the moon with the lunar module reflected in his visor. It is such a powerful image: one lonely figure in another world. And since Aldrin is anonymous inside his spacesuit, he seems to represent all humanity.’

Victor ultimately studied mathematics and physics at university, and he says he wanted to blur the boundary between art and science. Martin-Malburet says of the moon landing photos in particular, ‘Between 1968 and 1972, 24 privileged humans traveled a quarter of a million miles to a place that was not Earth and a record of it all exists. But the complete story has not been told. At the time, only a tiny fraction of the material was released to the media. The rest remained in Houston, unpublished.’

‘First human-taken photograph from space; orbital sunset, February 20, 1962, John Glenn [Mercury Atlas 6]. Estimate: £3,000-5,000. Offered in Voyage to Another World: The Victor Martin-Malburet Photograph Collection, November 6-19, 2020, Online’ Caption and image courtesy of CHRISTIE’S IMAGES LTD. 2020

Many of the images in the collection have not been seen by people outside of NASA and various research institutions. Many images didn’t include accompanying information, leaving Martin-Malburet to dig through NASA’s transcripts of space missions to determine when each photograph in the collection was captured, such as whether it was on the way into space or on the way back to Earth, information NASA didn’t record. Martin-Malburet also often had to determine who the photographer of each image was, as ‘crediting the author’ is very important to him. By collating the available information and filling in the gaps, we now, for the first time, have a more complete story of many important moments in our history of space exploration.

There are many great images in the collection, including a photograph of Neil Armstrong on the moon, seen below. For decades, even NASA didn’t know this image existed. Martin-Malburet determined that Buzz Aldrin picked up the camera only once and it was to record this photograph of the first man on the moon. Otherwise, Armstrong himself was the photographer for the duration of the mission.

‘The only photograph of Neil Armstrong on the Moon, July 16-24, 1969, Buzz Aldrin [Apollo 11]. Estimate: £30,000-50,000. Offered in Voyage to Another World: The Victor Martin-Malburet Photograph Collection, November 6-19, 2020, Online’ Caption and image courtesy of CHRISTIE’S IMAGES LTD. 2020

Further ‘firsts’ in the collection include the first image of the earth rising over the moon’s horizon. Ed White’s first spacewalk, seen is recorded as well, and is the first full-face portrait of the Earth itself captured during the very last Apollo mission.

Christie’s writes that ‘Anyone looking at such photographs is bound to feel awestruck.’ It continues, ‘So are they genuine art objects?’ To that question, Martin-Malburet answers, ‘They are absolutely works of art. Artists strive for new ways to express themselves, a visual vocabulary. The astronauts had the blank vistas of space as their subject and their canvas. And the fact that you have humans behind the camera is really important. They saw themselves as scientists, but somehow they embraced the sublime. Through them, art broke free of gravity.’

It’s a wonderful collection. To view the entire collection, visit Christie’s. While the images themselves certainly hold a lot of value, Martin-Malburet’s work in contextualizing each photograph and determining the photographer adds a lot. As mentioned earlier, bidding is ongoing and ends on November 19 or 20, depending on the lot in question. Each lot includes an estimated value, and the estimates range from around $ 1,000 USD to over $ 60,000.

Video: The history of cameras in space and how iconic space photos were captured

10 Oct

Astronauts have been taking cameras into space Soviet cosmonaut Gherman Titov orbited the Earth aboard the Vostok 2 in 1961. Since then, astronauts have used cameras to capture some of the most iconic photos of space exploration and created important memories for countless people back on terra firma.

As Scott Manley points out in his new video, How Astronauts Captured Iconic Space Photos – A History of Cameras in Space, although cameras are often modified for space flight, not every camera has been special. In fact, John Glenn bought a standard Ansco Autoset camera on his own, likely to avoid delays if he had gone through the standard government acquisitions process. NASA engineers modified the camera to make it easier to use while in space, including the addition of a pistol grip and an additional viewfinder that could be used with the suit helmet closed. You can learn more about Glenn’s Ansco Autoset in this article from the Smithsonian National Air and Space Museum. A second camera on board Glenn’s first orbital flight was a special Leica camera which had been modified to capture wide-spectrum images of stars.

Walter Schirra, pictured above second from the left, took a Hasselblad 500C camera aboard the Mercury Sigma-7 spacecraft. Schirra was a photography enthusiast himself and had asked professional photographers who had been following the space program for advice. On their advice, Schirra purchased the medium format Hasselblad and after it was modified for improved usability and performance, he used it to capture images during six orbits of Earth. The resulting images were very detailed and as Manley says in the video below, established a new standard for images captured in space.

Schirra’s Hasselblad camera was later used in the final Mercury mission by Gordon Cooper and was eventually sold at auction for $ 275,000 USD. If you would like to own a working replica of this same Hasselblad, Cole Rise makes replicas of space cameras, including the Hasselblad 500C. You can learn more about Rise’s cameras at Space Camera Co.

Thanks in large part to Schirra’s photography in space, Hasselblad cameras became important cargo aboard subsequent space exploration missions as part of the Gemini and Apollo missions. Hasselblad cameras were used outside of spacecraft as well, capturing many iconic images. One of these iconic images was of Edward White during his spacewalk in 1965. By this point, Hasselblad had begun working directly with NASA to develop cameras for space and had outfitted NASA with a custom-built Hasselblad 500EL data camera, complete with a silver finish for thermal control, special low-distortion lens and Reseau plate.

This custom-build Hasselblad data camera was used on Apollo 8, 9, 10 and 11 missions. Image credit: Hasselblad

Hasselblad has an informative website dedicated to its history in space, it is well worth checking out.

Near the end of the Apollo program, Nikon began working work NASA to outfit astronauts with customized 35mm SLR cameras. Nikon cameras are still used in space to this day. Some of the modifications made to make Nikon cameras suitable for space include different soldering standards, vacuum-safe lubricants and a more robust metal construction. You can learn more about Nikon’s history, including the use of its cameras in space, by clicking here. Manley also references Timm Chapman, a photographer who owns many Nikon space cameras. Chapman has written extensively about Nikon’s space cameras, including fascinating details on how they were modified.

Earth from 100,000 feet: Sigma sent the fp mirrorless camera into near space

03 Oct

Sigma UK recently collaborated with the company Sent Into Space to send a pair of Sigma fp full frame mirrorless cameras into the upper atmosphere. Sigma 14mm F1.8 lenses were used on each camera. It’s a notable kit because it combines the world’s smallest and lightest full frame mirrorless camera with the brightest full frame 14mm prime lens available.

The Sigma fp cameras and 14mm F1.8 lenses were attached to weather balloons and sent up to an altitude of roughly 19 mi. (about 30.5km). At altitude, the cameras captured high-resolution photos and 4K RAW video of Earth.

No good marketing operation is complete without stunning media to share with prospective customers. Sigma UK published a video to document the process of sending Sigma fp cameras into near space and show off the amazing results of the project.

The launches took place in Sheffield and the first Sigma fp to gain altitude was dedicated to recording 12-bit 4K UHD Raw video and the second camera was dedicated to capturing 24.6MP still images. Each camera was part of a kit that includes on-board equipment to provide data and telemetry back to the Sent Into Space team back on the ground.

The balloons, filled with hydrogen, expand considerably during the ascent. As the atmosphere gets thinner, the gas inside the balloon tries to escape to fill the vacuum. At a certain altitude, the balloon will fail and burst, and the equipment will return to the surface aided by onboard parachutes. As Chris Rose of Sent Into Space points out in the video above, the payload will actually descend at up to 250 mph before the atmosphere gets thick enough to act against the parachute.

Each camera was sent into space with an attached 2TB SSD drive. Even with that much storage capacity, the fp couldn’t record 4K UHD RAW video for the entire flight. The stills camera was set up with an interval timer to capture a still image every five seconds for the entire journey.

To learn more about the Sigma fp, head to our First Impressions. For more on the Sigma 14mm F1.8 DG HSM Art lens and its applications for space photography, check out Jose Francisco Salgado’s ‘Astrophotography with the Sigma 14mm F1.8 Art lens’ article.

Canon is sending a satellite with high-resolution camera tech into space

23 Jun

Canon will send its high-resolution CE-SAT-IB satellite camera into space as part of Rocket Lab’s next payload launch, enabling it to showcase its Earth-imaging capabilities. The private aerospace company, which is based out of California, aims to provide ‘frequent and reliable’ launches, something it will demonstrate by holding its upcoming ‘Pics or It Didn’t Happen’ launch only three weeks after its ‘Don’t Stop Me Now’ mission.

The launch will be coordinated by Spaceflight Inc., the company said in a press release last week. Canon’s CE-SAT-1B is a microsatellite at only 67kg (148lbs), not to be confused with the CE-SAT-IIB satellite, which is scheduled to launch via Rocket Lab later on this year.

The launch will take place on Rocket Lab’s Electron rocket from its Launch Complex 1 located on New Zealand’s North Island on July 4 local time. This mission will be called ‘Pics or It Didn’t Happen,’ the fourth Rocket Lab launch in the past year. The team had intended to launch the payloads earlier this year but were delayed by the pandemic.

In a statement, Canon Electronics Satellite Systems Lab group executive Dr. Nobutada Sako told Spaceflight:

This launch is very critical for Canon Electronics as we are launching a satellite where we have remarkably increased the ratio of in-house development of components compared to the previous launch. Partnering with Spaceflight on this mission has been very helpful and we look forward to a successful launch of our satellites.

Canon launched its CE-SAT-I microsatellite in 2017 from India, successfully putting its tiny satellite into orbit. The camera company detailed this effort on its global website, explaining that it already has many of the technologies necessary to build and deploy these small machines.

The CE-SAT-IB microsatellite is the first mass-produced version of the CE-SAT-1 from Canon Electronics. The satellite features solar cells and batteries for power, as well as an optical imaging system that is based on the Cassegrain 40cm telescope with a 3720mm focal length. The satellite’s detector is based on the Canon EOS 5D Mk.3 camera. With this tech, the CE-SAT-IB is able to capture Earth imagery with a resolution of 1m (3.2ft) from an orbit distance of 600km (373mi), according to NASA.

In its own announcement, Rocket Lab said last week that its launch will include a total of seven microsatellites with Canon’s CE-SAT-IB as the primary payload. Assuming everything goes according to plan, Rocket Lab plans to conduct additional launches every month for the rest of the year and into 2021. In addition to launching another Canon satellite in the coming months, Rocket Lab also anticipates its first launch for the U.S. Space Force for Q3 2020.

NASA astronaut Jessica Meir uses Nikon D5 to snap two space selfies

31 Jan

NASA astronaut Jessica Meir caught the public’s attention over the weekend when she published two selfies captured during a spacewalk using a Nikon D5 camera. Meir has shared a number of images from the International Space Station since her arrival in September 2019, though few were as impressive as her full-body selfie captured as a reflection in ISS solar panels.

Meir shared the images on January 26, tagging them with the #SundaySelfie hashtag. One is a traditional shot of her face while the other image is a full-body shot of Meir in her spacesuit as seen reflected in some solar panels. The Earth is visible as a bright band of light behind her, as are bits and pieces of the space station.

As for the camera, Meir explains that she used a Nikon D5 camera with a 28mm lens and special protective housing that enables the camera to operate in space. NASA ordered a total of 53 unmodified Nikon D5 DSLRs from the camera company in 2017 with the intention of using them for recording ISS activities, as well as vehicular activities and astronaut training.

Sotheby’s Space Photography auction includes NASA ‘Red Number’ prints

28 Nov

Sotheby’s auction house is holding an online Space Photography auction that includes multiple NASA ‘Red Number’ photographs, as well as vintage silver gelatin and other chromogenic prints featuring spacecraft, astronauts, and more. Sotheby’s estimates the prints will sell for between around $ 600 and $ 9,000 each, depending on the print.

The Space Photography auction features more than 200 lots featuring vintage prints, some of which are signed by Jack Fletcher, Buzz Aldrin, LMP Fred Haise and others. A large percentage of the photos are original NASA ‘Red Number’ prints, which means they’re chromogenic color photographs that include unique NASA image ID numbers printed in red in the photo’s margin.

Some of the space prints include a watermark, such as ‘This Paper Manufacturered by Kodak,’ as well as press captions printed on the back of the prints in purple ink. NASA ‘Red Number’ prints include the launch of the Skylab 4/Saturn 1B space vehicle, pre-launch preparations, the launch of Space Shuttle Columbia (STS-1), various shots of the Space Shuttles Discovery, Atlantis, and Challenger, and more.

The auction includes other non-Red Number vintage space prints, including three that feature UFO sightings that happened in Switzerland in the 1970s, vintage large format prints of iconic NASA lunar photos, and more. The NASA ‘Red Number’ prints come from the collection of Philip Kulpa.

A total of 140 photographs are available as part of ‘The Vintage NASA Photo Collection of Philip Kulpa,’ and they’re joined by a selection of prints from the estate of Bill Taub, NASA’s first senior photographer who covered all major NASA missions from the launch of Mercury to the end of Apollo. The online auction is open to bids until December 3, 2019, at 12 PM EST, according to Sotheby’s.
