This DIY ‘digiObscura’ digital camera features a massive 1-kilopixel image sensor

31 Dec

Creator Sean Hodgins has published a new video detailing his creation of ‘digiObscura,’ a large boxy digital camera that features his own 1-kilopixel image sensor. The camera’s creation involved 3D printing the camera body and soldering phototransistors on a custom printed circuit board alongside a pair of 32-bit analog multiplexers.

As you might expect, the 1KP images captured by digiObscura are very blocky and pixelated due to the camera’s very low resolution, but it’s an incredible look at what’s possible with enough time, patience and knowledge.

In addition to the video above, the project is detailed on Instructables, where tools and components are listed. More detailed information, as well as firmware and other files, are available on the project’s Github. Files for the 3D-printed components are available on Thingiverse.

This is how the Samsung ISOCELL Bright HMX 108MP mobile image sensor works

18 Dec

More recently we have seen a significant increase of resolution in high-end mobile image sensors, with market leaders Sony and Samsung launching sensors with pixel counts that are firmly in medium format camera territory.

However, in the mobile world, the high resolutions aren’t so much about an increase in detail. Instead, they allow for improved digital zooming with only a small loss in detail, and the option to use pixel-binning methods in difficult light conditions in order to improve noise levels.

Samsung has now published a video and blog post detailing the technology and improvements in its ISOCELL Bright HMX 108MP sensor that is deployed in the Xiaomi Mi Note 10 Pro and will likely also be used in the upcoming Galaxy S11 series.

The sensor’s large 1/1.33″ surface combined with 0.8?m-sized pixels allows for the massive pixel count and increased light gathering capability compared to smaller variants. It uses Samsung’s ISOCELL Plus technology which minimizes optical loss and pixel crosstalk by installing a barrier around each pixel.

Previously this barrier was made from metal. In this latest generation of ISOCELL sensors, it is now made from an ‘innovative new material that minimizes optical loss and light reflection’. Samsung says the material also allows the photodiode to absorb more light, allowing for much better performance than you would usually get from such small pixels.

In addition, Samsung has implemented its Smart-ISO technology which lets the sensor pick the best level of signal amplification for a given lighting situation, reducing highlight clipping and noise levels.

Samsung’s Tetracell Technology helps increase performance in low light by merging clusters of four pixels into single pixels, combining the native 0.8?m pixels into larger 1.6?m ones. Even in this mode, the ISOCELL Bright HMX sensor can still deliver 27MP image output which should be more than enough for any mobile application. The complete article is available on the Samsung website.

How to Avoid This Travel Photography Mistake: Taking Snapshots

10 Dec

The post How to Avoid This Travel Photography Mistake: Taking Snapshots appeared first on Digital Photography School. It was authored by Kevin Landwer-Johan.

When I teach travel photography workshops, I am always quick to encourage people not to rely on interesting subjects. An interesting subject does not always make a good photo. A good photographer does. So, in this article, you’ll learn to avoid just taking snapshots.

Travel snapshots

Taking snapshots when you travel is so easy. You find yourself in different, stimulating environments. They’re packed with exotic, compelling subjects provoking you to squeeze a quick photo as you rush by. Thinking the impressive subject is enough to create an appealing photograph is a mistake.

Pay attention to lighting, timing, and exposure. Taking snapshots without this care rarely hold anyone’s interest. You might find the most fascinating subject and not do it justice due to a lack of attention or time given to it.

Also, be careful of misconceptions about camera equipment. There are two main ones I notice.

‘I have a professional camera, so I take professional photographs’.

Just as a good subject does not make the photograph, nor does a good camera. A good photographer makes good photographs. Don’t rely on your camera to be creative. It cannot be. It is smart, that’s for sure. The artificial intelligence in modern cameras is phenomenal, but they are not creative. You are.

‘I only have my phone or compact camera so I can’t take good enough photos’.

You don’t need to stick to taking snapshots with a compact camera or phone. Don’t limit your creative expression because of the equipment you use. Sure, there are limitations with that kind of camera. You can still creatively capture interesting subjects when you put your mind to it.

Take your time

Slow down a little and think about how to make whatever it is that’s interesting into a great photo. Don’t rely on the subject alone. Every place you go, from Thailand to Turkey, you’ll find compelling subjects.

Something iconic needs to be treated with more imagination because everyone photographs it. To capture a photo of a monk in Chiang Mai or the Istiklal tram in Istanbul, you need to think outside the box. Everyone who’s been there has snapshots of these subjects.

Take your time when you find something engaging to photograph. Think about the lighting. Consider the best angle to photograph it from. Check out the background and make sure it’s relevant. Look at it for a while and ask yourself why you want to take a photo of it.

Don’t take only one photo

The first composition you make will not always be the best. Often it will be the most clichéd. The one everyone else takes.

Experiment with different angles and lens focal lengths. Make horizontal and vertical compositions. Try a dutch angle or two.

Always think about filling your frame. What’s within the edges of your viewfinder or monitor? Is everything you can see relevant and supporting your main subject? If not, do something about it. Change your angle, aperture or lens. Or wait. Sometimes you have to pause for people or traffic to move out of the background space. This will help your subject will stand out.

Be in control of your camera

Relying on an auto exposure mode and averaged metering gives you predictable results. Your camera is programmed to make even exposures. It’s not going to choose to expose for the highlights and let what’s in the shadows fall into blackness. Nor is it going to selectively slow down your shutter speed and purposefully allow motion blur to happen. You have to do these things.

Knowing your camera and how to control it will help you intuitively see when you can incorporate creative techniques. This will diversify the photographs you take. If you’re happy to use your camera like a point-and-shoot, then snapshots will fill your travel photo albums.

Taking your camera off the auto settings can force you to slow down (until you become more familiar with it). You can then think about all aspects of picture-taking at a more relaxed pace. Great photos are rarely quick.

Even most of the best street and travel photos are not taken on the spur of the moment. They are planned. They are preconceived. They are anticipated before the action happens, or the light becomes perfect.

When you do see something amazing happening and must react quickly, flick your camera back to auto. Take a few photos, and then, if you still have time, pop it back onto manual mode. Now you can get creative with your aperture and shutter speed.

Take a travel photography workshop rather than a tour

Many people use their camera predominantly when they travel. People have more time to take photos of interesting subjects when they travel. The problem is remembering all those settings. How can you get the most out of your equipment when you seldom use it?

Taking a travel photography workshop at the start of your vacation or journey will kickstart your creative process. You can learn to be more confident with your camera when you have a better understanding of how it works.

Picking up your camera and being stressed because you’re uncertain if it’s going to do what you want is not fun. A good tutor will walk you through the essentials of using your camera and build your confidence to do so.

A workshop will also give you hands-on experience on location. You’ll learn how to see the most interesting subjects and what to do with them. On a photo tour, all you usually get is a guide showing you interesting things to point your camera at. A workshop will equip you to take great photos wherever you go because you’ll learn how to use your camera in a multitude of different situations.

Avoid photographic clichés

It’s not difficult to avoid photographic clichés when you stop and think about it – even with iconic subjects. Slow down and enjoy the moment. Create a beautiful memory of it by thoughtfully composing your photos instead of taking snapshots.

Diversify your research. Don’t rely on Instagram to show you where the best photo opportunities are to be found. These are the places everyone will go and take the same boring pictures.

Think outside the box. Infuse your photos with creativity by looking for alternatives. Even if your subject is iconic, make it fresh and new in the way you choose to photograph it.

This Chrome extension makes Instagram ‘likes’ visible again

06 Dec

Over the past several months, Instagram has steadily removed publicly visible ‘likes’ from content posted on its platform, a decision that has polarized users. As the company explained earlier this year, hiding ‘likes’ removes the competitive feel from the platform, encouraging users to focus on the content, not how many people are engaging with it. A new Web browser extension changes that.

Called ‘The Return of Likes,’ this new Chrome extension enables users to view like and comment counts on images when browsing Instagram using a Web browser. ‘Instagram has stopped displaying the number of likes and comments in some areas,’ developer Socialinsider explains, ‘[and] that makes the life of a Social Media person very complicated so we thought about lending a hand.’

‘The Return of Likes’ extension is available in the Chrome Web Store now; it doesn’t appear to be available for any other Web browsers at this time.

Sony Is Now Beating Nikon in Camera Sales. What Does This Mean for the Industry?

03 Dec

The post Sony Is Now Beating Nikon in Camera Sales. What Does This Mean for the Industry? appeared first on Digital Photography School. It was authored by Jaymes Dempsey.

Sony-beating-Nikon

According to Nikkei, Nikon has now dropped behind Sony on overall camera sales, leaving the market with these adjusted rankings:

Canon, #1.

Sony, #2.

And Nikon, #3.

This hardly comes as a surprise, given recent market trends in digital camera sales, along with Nikon’s recently forecasted loss in imaging products (instead of an originally predicted profit).

The truth is that digital camera sales are bleeding across the board, not just for Nikon. In recent years, sales have dropped for Canon, Nikon, and Sony, but Nikon’s poor performance has allowed Sony to creep past them in the rankings.

Note that Sony was already leading the industry in full-frame camera market share, and was also leading Nikon in interchangeable lens camera sales.

In other words: Sony’s success is simply another step on the road to its digital camera dominance.

For Nikon shooters, this is far from good news. As of right now, Nikon’s full-frame mirrorless lineup is in its early stages, with only two cameras and a handful of lenses. But if Nikon decides that its imaging business is costing too much money, the leadership may decide to head into the safer waters of its precision equipment business (where Nikon is performing well and profits are steadier).

If this happens, we could see a decline in both the number and quality of Nikon products.

And then, assuming that digital camera sales continue in the downward direction, and assuming that Canon and Sony continue to push for market dominance, we might see the end of Nikon’s imaging business, period.

Is speculating about the end of Nikon cameras a bit alarmist?

Maybe.

But reports regarding camera sales have been nothing but alarming in recent years, defying expectations and suggesting that things are changing faster than anyone could have predicted. And with recent speculation about Olympus’s camera business shutting down, well, it’s hard not to wonder.

So what do you think? Will Nikon remain competitive in the camera industry? Or will the company decide to focus on other areas and drop its image business entirely?

Let me know your thoughts in the comments!

Which online printing service should I use this holiday season?

26 Nov

Introduction

The holidays are right around the corner, and if you plan to send out cards or make prints as gifts you’re probably in the midst of figuring out where to get your photos printed. There seem to be more options than ever when it comes to online printing services, which makes choosing one a bit overwhelming.

So to figure out what service you should use, we tested out five popular online printing companies and assessed them based on their ease of service, price, turnaround time and most importantly, print consistency/paper quality.

Print services:

  • Printique
  • MPix
  • Amazon Photos*
  • Shutterfly
  • Snapfish

We placed an order for three 8×10 and three 4×6 prints on the same day (October 23rd) from Snapfish, Amazon, Shutterfly, MPix, and Printique (formerly known as AdoramaPix). We used the automatic ‘smart crop’ feature on each website when preparing the prints and, when it was possible, requested that the image be printed on Lustre paper. All prints were shipped with the economy shipping option.

After receiving and assessing our prints, the service you should use this holiday season is…

Our choice: Printique or MPix

We recommend ordering your holiday prints from either Printique or MPix. These companies had the most consistent results and were the truest representation of the digital files that we uploaded.

Although all of the print services are fairly easy to use, the winners are pretty clear. Based on our print orders we would gladly recommend ordering from Printique or MPix. These companies had the most consistent color results, the best paper quality and were the most true to the digital files that we had uploaded through the sites. They aren’t the cheapest options on the list, but they are also not the most expensive – at $ 16.72 (Printique) and $ 13.96 (MPix), they both fell in the mid-range level in terms of pricing. MPix did offer a nice 25% discount on our order and it arrived a few days before the order from Printiques. But we preferred Printique’s overall photo/paper quality.


Now let’s take a closer look at each of these print services including the process of ordering, the speed of delivery, the condition prints arrived and the overall quality of our purchase. First up is Printique…

This designer end table also functions as a Lightbox for product photography

22 Nov

A Red Dot Design Concept Award for 2019 was recently given to Photo Table, a design concept that transforms a lightbox into a piece of furniture that can be used to display decorative items. The table has a simple, modern design with a dome frame and internal light.

The concept comes from designers with South Korean company Zinus Inc, which says about Photo Table:

For this furniture to be used as a side display table, it should blend in beautifully with any living space, while serving as a tool to make pictures more. To express your lifestyle, directly record personal collections and crafts on the Photo Table and share the images via social media in an instance.

The concept involves a design that can be packed flat and assembled using ‘a minimum number of bolts.’ When assembled, the semi-transparent PET panels form the frame ‘walls,’ which are interchangeable using clips; the background is also described as interchangeable. The table was designed to hide outlines and allow light from external lamps to penetrate, ultimately providing a space where items can be rapidly photographed.

The company doesn’t say whether there are any plans to commercialize the design, but it remains a fun concept that could easily inspire photographers who have the right DIY skills for making their own version.

News: Could This Sea-Thru Algorithm Be the Future of Underwater Photography?

18 Nov

The post News: Could This Sea-Thru Algorithm Be the Future of Underwater Photography? appeared first on Digital Photography School. It was authored by Jaymes Dempsey.

Underwater photographers may soon have a way of “removing water” from their photos, based on research done by Derya Akkaynak and Tali Treibitz at the University of Haifa (read report here).

As explained by Akkaynak and Treibitz, “An underwater photo is the equivalent of one taken in air, but covered in thick, colored fog.” And while the precise effects of water on images is somewhat technical, it doesn’t take much to recognize that water degrades images, causing a loss of both clarity and accurate color.

Enter Akkaynak’s Sea-thru algorithm, which is designed to remove color casts and other optical problems created by water. In other words, it can be applied to an underwater photo, one that’s blue (with inaccurate colors), and turn it into something that looks like it was taken on land.

For examples, check out the images in the Scientific American video:

??

How it works

But how was the algorithm actually developed, and how does it work?

Basically, Akkaynak took a series of underwater photos, making sure to place her color chart into the scene for an accurate reference. She ultimately compiled over a thousand images in several environments. From the reference images, Akkaynak and Treibitz developed a model that takes into account the unique ways that light interacts with water in order to correct underwater images for color and light.

Now, Akkaynak and Treibitz had academic purposes in mind when they conducted this research. The algorithm, as presented in the original research paper, is meant to “help boost underwater research at a time when our oceans are increasing stress from pollution, overfishing, and climate change,” by giving researchers better access to visual data from underwater cameras.

But it’s easy to see how the Sea-thru algorithm could be relevant to underwater photographers everywhere. If Sea-thru can make photos become more accurate and (often) more vivid and colorful, might underwater photographers like to use it on their own images?

On the other hand, there’s the question of whether the best underwater photos convey an authentic sense of the (underwater) environment. Without the blue tones of water and the haze that water provides, photos may lose the sense of wonder that comes from doing work under the sea.

So let me ask you: Do you prefer underwater images where the water is much less apparent? Or do you like more authentic underwater photos, color cast and all? Would you be interested in the Sea-thru software?

Instagram CEO says it will start testing hidden ‘likes’ in the US starting this week

10 Nov

After testing it in numerous other regions, including Brazil, Japan, Canada and Australia, Instagram has confirmed it will start hiding ‘likes’ for accounts based in the United States this coming week.

The confirmation comes from Instagram CEO Adam Mosseri during the below interview at WIRED25. In it, he says certain users in the United States will have ‘private likes’ as soon as this week. Based on how Mosseri addresses the crowd, it appears as though the rollout will be random.

While elaborating on why Instagram is looking to test this, Mosseri said:

It’s about young people. The idea is to try and depressurize Instagram [to] make it less of a competition [and] giving people more space to focus on connecting with people that they love [and] the things that inspire them.

It very much seems as though this is a work in progress, far from being set in stone, so initial feedback will likely play a major role in whether or not this feature — or mores the lack of a feature — sticks around.
