Report: Chinese company Xiaomi may purchase GoPro

13 Apr

Chinese electronics company Xiaomi is considering an offer to buy action-cam makers GoPro, according to a report in The Information. This news follows GoPro’s January announcement that it would be exiting the market for drones in order to streamline business and become more profitable. At the same time, CEO Nick Woodman said in an interview with CNBC the company was open to a buy-out:

If there are opportunities for us to unite with a bigger parent company to scale GoPro even bigger, that is something that we would look at.

Details on the potential offer are sparse at this point in time, but the deal could be worth as much as $ 1 billion. Once valued at more than $ 10 billion, in its heyday GoPro was a success story in consumer electronics, but the company’s market capitalization has since fallen to about $ 761 million, mainly due to aggressive competition from China.

According to analysts, a buyer could leverage GoPro’s brand and make profits through device sales. Xiaomi in particular could also use some of GoPro’s camera IP in the development of camera modules for its smartphones. That said, if the Chinese company does end up buying GoPro, we hope they won’t just use the brand name and patents, and will let GoPro action-cams live on.

GoPro’s stock price has spiked 8.8 percent on the news.

The RedRock DigiBoom is a gimbal-stabilized camera boom

13 Apr

Cinema and video accessory makers Redrock Micro have teamed up with Disney/ABC Television Group and Disney Research to design and develop the DigiBoom, a handheld gimbal-stabilized camera boom.

The DigiBoom is targeted at solo operators and small production teams who want to add unusual angles and smoothly stabilized footage to news, sports, and event video productions. The DigiBoom lets you place the camera anywhere from ground level to more than 8 feet (243 cm) up; 12 feet (365 cm) with the optional extension.

Redrock Micro says the DigiBoom is ideal for creating sweeping camera moves or unusual points of view. Key Features include complete control of operation and settings for both camera and gimbal from the grip, automated, manual, or hybrid control of camera aim and angle, and professional audio-connections and functions.

Additionally, the device comes with a single power source for camera, DigiBoom, and accessories, and the option to use an external power input. A high-resolution display allows for full-time monitoring. DigiBoom can be used with a wide range of cameras and displays but Redrock Micro recommends the Blackmagic Video Assist and Micro Studio Camera 4K recorder and camera for best performance.

The DigiBoom can be preordered for $ 500 on the Redrock Micro website, where you’ll also find additional product information. Target availability is Summer 2018.

Core DigiBoom technology and associated patents were developed by Disney/ABC Television Group and Disney Research, and licensed to Redrock Micro to bring DigiBoom to market. DigiBoom has been field tested and refined over the past two years in organizations including Disney/ABC, ABC News, Marvel, and continues to be widely used at ESPN for live and recorded sports coverage.

“Over the past two years we have seen DigiBoom deliver tremendous value to Disney/ABC, ESPN and other subsidiaries within the Disney family,” said Anthony Accardo, Director, Research & Development, Disney/ABC Television Group. “Through our collaboration with Redrock, we are really pleased to see DigiBoom come to market and help elevate the state of the art for the industry.”

“DigiBoom gives us a distinctive look – delivering high-quality, cinematic images in a portable and versatile package,” said Brian Kennedy, vice president, Global News Gathering Operations & Planning. “At the 2017 Presidential Inauguration in Washington, D.C., DigiBoom provided incredible images and was the perfect tool allowing us to be live inside the story. No other tool could have delivered this type of coverage.”

“The Rose Bowl is one of the most beloved and most watched football contests in the US today,” said Lorenzo Lamadrid, ESPN Supervising Director, Rose Bowl. “Our use of DigiBoom for the 2018 Rose Bowl really enhanced the quality of the footage and sharpened the sense of ‘being right there in the action’ for our viewers. DigiBoom worked beautifully to create shots we couldn’t otherwise achieve.”

“DigiBoom allowed our camera operator to access high traffic spaces and deliver angles that wouldn’t have been possible with a traditional camera,” said John Vasallo, Sr. Coordinating Producer for ESPN.

Blackmagic Design Cameras Unlock DigiBoom’s Potential

DigiBoom can be used with any appropriate camera and display. To get the most from DigiBoom, the preferred recorder and camera are the Blackmagic Video Assist and Micro Studio Camera 4K, the world’s smallest broadcast quality live production camera.

The unique connectivity of the Micro Studio 4k Camera’s expansion port gives operators fingertip control over all camera functions directly from the DigiBoom handgrips.

Video: $7000 superzoom lens + DSLR compared to $35 smartphone lens

13 Apr

NYC-based filmmaker Casey Neistat recently compared a $ 35 clip-on smartphone lens with a $ 7,000 DSLR (the Canon EOS-1D X Mark II to be precise) and superzoom lens. The results, to no one’s surprise, were not in the smartphone lens’ favor. However, Neistat expresses surprise at the (admittedly very minor) capabilities of the cheap lens, saying, “So, I very gently, very reluctantly, recommend this total piece of sh*t $ 35 lens because it sort of almost works.”

That recommendation is given to potential buyers who need something to use with a smartphone. If a more capable lens and camera are within budget, the resulting content will benefit greatly from them, as the comparison screenshot below pretty clearly demonstrates:

Dunning-Kruger Effect: Why you’re not as good a photographer as you think you are

13 Apr

Have you ever noticed that as you learn more about the world of photography, you tend to realize just how little you actually know? This phenomenon is what’s referred to as the Dunning-Kruger effect.

London-based photographer Jamie Windsor recently took to his YouTube channel to explain what it is, how it affects you and your work and even shares five things you can do to overcome thinking you know more than you actually do.

A chart from the video showing how perceived ability compares with actual ability according to the Dunning-Kruger Effect.

As explained in the video, the name of the phenomenon came from two social psychologists David Dunning and Justin Kruger. During a study, the two recognized that the less competent someone was at a given task, the better they thought they were. Put more simply, if you think you’re a great photographer, there’s a good chance you’re not nearly as amazing as you think you are.

Almost everyone falls victim to the Dunning Kruger effect at some point in their career. But the more self-aware you can become, the less likely you are to fall into the trap of being a bad photographer who thinks they’re good. To help combat this downward spiral, Windsor shares a few tips, which we’ve paraphrased and elaborated on below:

  1. Beware of feeling comfortable – If you start feeling comfortable in your abilities, try something new and expand your horizons. Don’t get complacent.
  2. Learn to let go of old work – Always try to one-up yourself and make your next shot your best shot. If you still think that shot from four years ago is your best, you probably haven’t improved much.
  3. Ask for feedback and constructive critique – It’s not always easy to hear, but an outside perspective can help you get a broader and more realistic view of your skills and ability.
  4. Always keep learning – “You have never learnt everything.” Never think you’ve finished learning something—everything is a rabbit hole of knowledge.
  5. Feeling bad about your old work is a sign of progress – Thinking your old work isn’t great means you’ve learned where you’ve fallen short and know how to improve your work.

In the end, Windsor emphasizes that no matter what you think of your work or how far you’ve come, it’s ultimately about enjoying the ride. His parting piece of advice is to ‘learn why you’re doing things, not just how to do them’.

Tips for Learning How to See the Light and Take Better Photos

13 Apr

Your camera can’t see the light and tones as well as you can. Cameras have not yet been developed to a stage where they can record a tonal range in a single, unmanipulated image as broad as you can see with your eyes.

Portrait of a senior woman being made by a photographer - Tips for Learning How to See the Light and Take Better Photos

Our brains are constantly evaluating the light and making adjustments dynamically so you get to see far more detail in the brightest and darkest areas of whatever you are looking at, as well as in the mid-tones. Understanding this difference between what you see and what your camera records will help you to become a more creative photographer, (and save you time post-processing your photos.)

Different Types of Light

Basically light can be hard or soft, direct or diffused. Direct light, usually from a relatively small light source, creates a hard-edged shadow, like on a sunny day. Light that is diffused, like you experience when the sun is behind a cloud, makes soft shadows or virtually no shadows at all.

Woman selling fresh fruit at a market in Chiang Mai - Tips for Learning How to See the Light and Take Better Photos

Hard light – characterized by high contrast, hard edges, and lots of texture and detail.

Unloading produce at a market in Chiang Mai, Tips for Learning How to See the Light and Take Better Photos

Soft light is characterized by gentle or no shadows, lower contrast, and less texture and detail.

Light will have various other qualities as well depending on the time of day, season, atmospheric conditions, and geographic location. Light can be warm and have a golden tone, mostly in the mornings and evenings. It can also be cold and have a bluish tone, often in city streets where buildings block the sun or on heavily overcast days.

Different Tonal Ranges

Typically with soft light, you have a narrower tonal range (lower contrast). In conditions with soft light, your camera will be more capable of producing images with detail in the shadows and also the highlights, if you expose your photos well.

Tricycle Taxi Rider in Chiang Mai, Tips for Learning How to See the Light and Take Better Photos

Soft Light

With hard light, the tonal range between the brightest and darkest parts of an image can be far more extreme. Your camera may not be capable of recording detail in the highlights and in the darkest parts of your image, in a single frame (I am not concerned with HDR or other manipulations here).

Street scene in Thailand with tricycle taxis and traffic - Tips for Learning How to See the Light and Take Better Photos

Hard Light

As you learn to see light and understand the type of light in which you are photographing, you will get a feel for it and become more creative and more precise technically with your photography.

Using Light to Fit the Mood

If you want to create a gentle portrait with soft, relaxing tones you will not just need your subject to be in the right mood, but you will need the lighting to fit with the mood as well. A soft, diffused light will help you reach your goal whereas trying to create this style of portrait outdoors in the middle of a bright sunny day will be far more difficult.

Portrait of a young Kayan girl - Tips for Learning How to See the Light and Take Better Photos

Soft light here allows for detail in all areas of the image and for a flattering portrait of the girl.

Sometimes working with soft light can be challenging if it is just too flat and dull and offers very little tonal range in your subject. In these situations, I will look to add some alternative light source from a flash or reflector to add a more dynamic look to my photos.

Hard light can make for more dramatic pictures. Using the contrast range so parts of your composition are isolated, either because they are too bright or too dark for your camera to record, is often an effective method towards producing more creative photographs.

Close up of a Hmong woman hand sewing - Tips for Learning How to See the Light and Take Better Photos

The hard light here highlights the hands making the background completely black.

Carefully Control Your Exposures

Taking control of your exposure so you are only rendering the detail in the highlights and allowing the shadow areas to show little or no detail, is a great technique to learn. Alternatively, in hard light situations, you can set your exposure for the dark areas of your composition and you will lose detail in the highlights.

Photographers who are more technically oriented and believe you must have an evenly exposed image with no loss of detail may struggle with this concept.

Buddhist monks walking in the morning, Tips for Learning How to See the Light and Take Better Photos

When you have a concept for a photograph (or series of photographs) you want to make, creating the photos in the best lighting will have a significant impact on your results. Choosing the optimum lighting to create the feeling you want to capture in your photo brings a greater depth to your pictures and more feeling of connection with those who view them.

Concerning yourself primarily with technical details will not have the same effect in many cases.

Getting Creative With Light

Lighting can be a bit of a dilemma if it does not fit the mood or scenario you are wanting to photograph. Pushing yourself to create interesting, captivating images even when you are faced with adverse lighting conditions is a great challenge to embrace and will help you grow as a photographer.

Street festival in Mae Hong Son - Tips for Learning How to See the Light and Take Better Photos

I used some off-camera flash here because the ambient light was very flat.

Pay attention to the light wherever you are, even if you don’t have a camera with you, just see light. Think about it. Consider the qualities of light and how they will affect the photos you take.

Will the light help you or hinder you in creating the style of photographs you want to make?

Learn to See Light

If the light is not right for what you want to achieve in your photos you will need to make changes by adding light, from a flash or reflector or another additional light source. Sometimes even just changing your point of view in relation to your subject will have a significant influence on the mood and look of the lighting. For example, using backlighting instead of front or side lighting.

The more you can learn to see the light and understand how it will affect your images, the more creative you can become with your camera. There are some additional tips in the video below to help you see the light.

Tiny micro-camera sensor is self-powered by light

13 Apr

University of Michigan engineers Euisik Yoon and Sung-Yun Park have developed a nearly microscopic image sensor that doesn’t require an external source of power. Measuring less than a millimeter across, this prototype camera could be placed just about anywhere – it only requires a light source to harvest energy. The technology is detailed in a study recently published in IEEE Xplore.

This isn’t the first self-powered image sensor project, however earlier explorations of the technology had limitations. One previous example involved embedding photovoltaics into a sensor for harvesting the energy to power it, which reduced the amount of light available to produce the image.

When put to the test, the sensor was able to capture 15 images per second

The prototype created by Yoon and Park differs, instead sensing the image and harvesting energy simultaneously without reducing the sensing area. This is made possible by placing a second diode, which acts as a photovoltaic, beneath the photodetector. When exposed to daylight, some photons pass through the initial photodetector diode, where they then reach the second diode and are converted into electricity to power the sensor.

With this arrangement, the sensor’s pixel area is almost fully dedicated to capturing the image while the “waste” photons are grabbed to power the camera. When put to the test, the sensor was able to capture 15 images per second at the quality shown below.

The number of frames that can be captured per second depends on the amount of available light. Full, sunny daylight at 60k lux provided enough power to capture 15 frames per second, though normal daylight at 20k to 30k lux produced enough energy for half that rate at 7.5 frames per second.

Eventually, as IEEE Spectrum notes, the proof-of-concept prototype could be refined to improve its efficiency in lower lighting conditions. The engineers could also choose to embed other components, such as a tiny wireless transceiver, to create a complete wireless camera capable of being placed and operated nearly anywhere.
