In-camera, optical tilt shift is now achievable

I’m not sure when it clicked for you that tilt shift could be had easily and practically, in camera with some recent models, but that time was today for me.

Tilt–shift photography is the use of camera movements that change the orientation and/or position of the lens with respect to the film or image sensor on cameras.

Sometimes the term is used when the large depth of field is simulated with digital post-processing; the name may derive from a perspective control lens (or tilt–shift lens) normally required when the effect is produced optically.

“Tilt–shift” encompasses two different types of movements: rotation of the lens plane relative to the image plane, called tilt, and movement of the lens parallel to the image plane, called shift.

Tilt is used to control the orientation of the plane of focus (PoF), and hence the part of an image that appears sharp; it makes use of the Scheimpflug principle. Shift is used to adjust the position of the subject in the image area without moving the camera back; this is often helpful in avoiding the convergence of parallel lines, as when photographing tall buildings.

Tilt-shift photography, Wikipedia

The only mainstream lens manufacturer I know of that sells tilt-shift lenses is Canon. While I like Canon cameras and love the capabilities of tilt-shift lenses, I would like to see if there are other ways to handle this issue. It’s somewhat of a niche problem, but it’s one that’s worth addressing.

And then it dawned on me. Some camera models have sophisticated 5-axis image stabilization. That means they effectively tilt and shift the sensor, along with “shake it all about” and so on, in order to keep a longer exposure clear. But what if we were to modify the firmare, to introduce a special section in the camera menus, where the vertical and horizontal angles at which the sensor is kept when facing a scene could be manually adjusted through that special section? We could effectively introduce optical tilt and shift capabilities by manipulating the sensor, while still using the same lenses.

Lightroom offers some options to tilt and shift the image after it’s been taken, but any good photographer will tell you it’s better to capture the image you need directly in camera. Introducing a special menu that lets us tilt and shift the sensor, perhaps using the buttons and dials already built on the camera, would provide this valuable niche capability to those who do not own Canon tilt-shift lenses and do not shoot with Canon cameras. It’d literally be a bonus firmware upgrade that could be pushed out and the new feature should just work. There would be some limitations in the amount of movement, since the IBIS engine wasn’t originally built for this, but it would work, and in future iterations of the IBIS, I’m sure it would work even better.

The flip side of digital photography

Should you be old enough, you’ll remember how different photography was before the arrival of digital cameras. Not only was it difficult to get great photos, the kind that were good enough for publication, but it was difficult to develop them and reproduce them. There were real barriers to entry and to success in the field. They weren’t insurmountable, but they were there.

Nowadays, digital cameras make it so easy for us. Even a novice can occasionally get a great photo simply by clicking the shutter button, because modern cameras can pretty much handle all situations. They don’t do everything, you still need to know what you’re doing in some scenarios, but they’ll get you pretty close to your desired result by themselves, most of the time. So not only is it easy to take photos, but it’s also easy to “develop” them using your computer, and you can reproduce them endlessly. The barriers to entry and success in the field are now almost gone.

However, one thing we all learn as we age is that everything comes with pluses and minuses. Just like film photography had certain minuses, digital photography comes with plenty of unpleasantries on its flip side.

Publications that used to hire photographers and pay them good wages are dwindling. How many do you know of that still have on-staff photographers, or hire photographers for their stories? And how do their salaries compare with those of photographers in the past if they’re adjusted for inflation?

Stock agencies are decreasing the payouts to photographers. There is a lot of competition in that market, paired with a real glut of photographs. And when the supply always outnumbers the demand, prices will fall. There are but a few stock agencies left. There are a ton of microstock agencies which sell photos for piddly sums and pay cents on the dollar to photographers, and they’re also getting bought out and merging with each other in order to survive. If it wasn’t clear a few years ago, it’s becoming painfully clear now that a photographer cannot make a living selling microstock. There are a few who manage to do it, but it’s clear that on average, microstock yields a non-livable income.

There are so many photographs being made that people don’t truly appreciate them anymore. Do you remember how we used to admire photographs in the past? We’d stare at them for 5-10 minutes at a time, taking in each detail. We’d cut them out of magazines and paste them in scrapbooks. We’d look at them and look at them and look at them… Now we’re lucky if a photo gets 5 seconds of someone’s time. There are so many of them that people just gloss right over a photo that took days or hundreds of tries to make. Perhaps you’ll understand this better if I compare it to a periodical cicada emergence. In just a few days, animals that would eagerly consume them as they came out, would become so glutted that they’d simply lay on the ground and watch them crawl around and over them, unable to eat a single morsel. That’s what’s going on with photographs now. Each of us has a rhythm, a rate of “ingesting” digital content and we’ve all reached our max, but the photographs just keep coming. They keep coming and their rate of production is actually increasing. We cannot keep up.

Digital photography gear is made to become obsolete, causing you to spend more money every few years. Remember how you could use the same film camera for 10-20 years, even a lifetime, if you took care of it? That’s not the case with digital cameras, which typically last about 4-5 years before something goes bad. Even if you’re willing to pay a repair shop to have it fixed, camera manufacturers stop stocking parts for older cameras after a certain number of years, because they want to force you to buy a new model. I wanted to send my Canon 5D in for repairs last year, but I couldn’t. The repair shop said I shouldn’t bother, because Canon actually doesn’t allow them to work on the 1st gen 5D anymore and they’ve stopped stocking parts. Not that Canon repair experiences were so great to begin with, but at least they got the job done. I also sent in my Olympus PEN E-P2 in for repairs last year, but it didn’t get repaired. It came back just as I sent it, with a message that offered apologies for the inconvenience and explained that they’d stopped stocking parts for that model just a few months back; support had been discontinued by Olympus. I don’t understand it: there’s money to be made with service and repairs, so why stop supporting a model? Why not keep servicing it for as long as the customer is willing to use it? That business model has been proven to work a long time ago by the car industry.

Cameras, lenses and flashes are getting more expensive each year. Manufacturers can call them inflation adjustments all they want, but price hikes still feel very much like price hikes. And when they’re coupled with no real way to make money from your photos anymore, what are you left with? Doing weddings? Yuck. I don’t know how photographers are coping with all of this. I have a nagging feeling that wedding photographers are pretty much the only ones making money from photography these days. They’re certainly the bulk of the paying customers for camera manufacturers. It’s them and the online “experts” that have sprouted like mushrooms after rain, offering “advice” about which camera model to buy on YouTube and other video sites. It’s a new model/brand each week of course, unless they’re getting paid by a manufacturer to promote a certain brand.

There are real costs associated with processing, storing and archiving digital photographs. We’re told that digital photographs are pretty much free and there’s never been a better time to take many, many photos in order to learn the craft, but there are significant costs that come into play when you add the price of a good computer and good software and the storage and backup solutions that you will absolutely need unless you want your photos and your hard work to go up in a puff of virtual smoke. I’d like to challenge you to add up the costs of your camera gear (camera, lenses, flashes, adapters, tripods, etc.) and computer equipment (laptop/desktop, external hard drives, backup equipment/services) and once you have a total, divide it by the number of photographs you’ve taken with your camera so far. That’ll give you a pretty good idea of the cost per image, and you’ll see that digital photographs are not free. Granted, that cost per image will go down the longer you keep your current equipment and the more photos you take with it, although the cost of storage and backup will still be there for your larger collection of photographs. Do you realize you’ll likely need to pay for a backup subscription for the rest of your life? It’s no wonder that more and more people choose to take photos with their smartphones and edit them directly on those devices, forgoing the cost of computer equipment. And when smartphone manufacturers also offer direct and almost instantaneous cloud backup of the images and videos taken with the phones (at somewhat reasonable prices) it becomes a very attractive offer.

It’s so easy to reproduce digital photographs that it’s actually a problem, because anyone can steal and plagiarize them. Theft of online photographs is rampant. It’s one thing for a fan to repost your photos on another site — I’d go so far as to say that’s fine… but it’s quite another thing for someone to download your photos, enlarge them in Photoshop and repost them on a stock site or use them in ad campaigns, and this is happening quite a lot.

There is no consistent way to attribute photographs online, which means a photographer’s name is likely to get lost in the shuffle. Sure, you can use a caption that lists the photographer’s name, but that only works if you’re the primary publication and you’ve worked with the photographer. Most software used to export and compress images for online publication generally strips EXIF and IPTC copyright information. And most online platforms also have no consistent way of keeping that information inside the photographs, instead offering excuses about file size and compression algorithms which sound very empty given how far we’ve come with computer technology. Have you ever tried to find a photographer’s name for a photo reposted on social media? Good luck… Unless they’ve got a tasteful watermark somewhere on the photo, the metadata’s been wiped clean by these sites. Even Flickr still does not keep a photographer’s name in the metadata of a photo. Should you be able to download a photo from a Flickr contact, you’ll get a link to the page where it was found and maybe a caption, but you will not get something as basic as the photographer’s name, much less the rest of the copyright information.

I’m not saying we should go back to film and analog equipment. I love digital cameras and their ease of use. And I love the various advances being made in digital camera gear. Some of the minuses listed above can even be fixed. I’m just not enthusiastic about their flip side. When photographs were harder to make, we appreciated them more and good photographers stood a good chance of making good money with them. Now that photographs are easy to make, we don’t appreciate them and income from photographs has gone down to pennies on the dollar, if at all. Thank goodness I take photographs for the sake of it, as a creative endeavour that relaxes me after working on my various projects, but I wonder how others are coping with these changes. And it’s also not to say that I wouldn’t mind making money from my photographs on my own terms.

How to choose a camera that’s right for you

In this video, I’m going to walk you through a process that will help you choose the right camera for your needs; it’s the same process I use myself as I choose new photo and video gear. Here are the decision-making steps I talk about in the video:

  1. Love what you already have
  2. Learn to use your equipment properly
  3. Don’t stress out about resolution (megapixels)
  4. Don’t get on a tech merry-go-round
  5. You don’t need UHD (4k video) just yet
  6. Be wary of “filler resolution”
  7. Separate the “nice to have” from the “must have”
  8. Get separate photo and video gear in order to obtain the best quality images and video

I hope this helps you!

Released 17-02-2018

It may seem like what I say in this video about camera resolution and about separating the equipment you purchase for photograph and video is contradicting what I say in this post, or in this post, but it isn’t that. I’ve done a lot of research and I’ve given this topic a lot of thought, and I’ve simply become more nuanced in my understanding of many aspects of digital cameras; when I sat down and thought about what kind of advice I wanted to give in this video, the statements I made above rang truest.

Thanks for watching!

My thoughts on Sigma DSLRs

I made a video follow-up to my past articles on Sigma DSLRs (see this and this), where I talk about where Sigma is today and why I think they’re lagging behind the market by 2-3 years.

Sigma’s R&D has not developed new DSLRs fast enough to keep up with market demands and the wonderful capabilities of the Foveon sensor are not put to proper use.

The Foveon sensor is remarkable in that it captures RGB color at each pixel due to its three plates (vs. a single plate in regular sensors). It is supposed to give much more accurate color reproduction than regular sensors.

Unfortunately, because Sigma has not worked fast enough to create DSLRs that can truly compete with those made by more popular camera makers such as Canon and Nikon at all leves (including, but not limited to low light performance and HD video), its DSLR arm now finds itself in a terrible slump.

Their latest offerings, the SD15 and the SD1 have not sold well, and I hope they do something soon in order to catch up with consumer expectations.

What happened to Sigma and FujiFilm DSLRs?

A few years ago, there were two companies which had some interesting opportunities ahead of them: Sigma with its revolutionary Foveon sensor and lens-making know-how, and FujiFilm with its remarkable Super CCD SR sensor and long-term experience with professional lens-making.

They didn’t stay on course. Sigma’s continued development of the sensor has been much too slow to keep up with the market, and FujiFilm seems to have dropped out of the DSLR game altogether.

Back in January of 2007, I wrote about the Sigma SD14, a camera I thought was revolutionary because of its capability of capturing every color (Red, Green or Blue) at every pixel, due to its layered Foveon sensor. This was something no other camera on the market had.

The megapixel game isn’t everything and I was willing to believe so in the case of the SD14. Its advertised resolution was 14 megapixels, but its true resolution was about 5 megapixels. That’s because each layer of its Foveon sensor (there are three layers, one for each color) only captured 5 megapixels. When you looked up the photos resolution in the EXIF data, it came out to 5 megapixels. When you zoomed in at 1:1, the photo still only covered a 5 megapixel area. People pointed out that you could safely increase the resolution of processed images to 12 or 14 megapixels and they would still have the quality you need but in my book, 5 megapixels is still 5 megapixels even if you can multiply it by 3 and get 14 megapixels.

Regardless of my disappointment with the camera’s real resolution, I still thought Sigma had a gorgeous sensor on their hands. The ability to capture color accurately at every pixel is something other sensor manufacturers only dream about. Their sensors don’t do that. Instead, they spread Red, Green and Blue pixels around the entire sensor area using a mathematical algorithm called Bayer interpolation, then they do some very serious calculations to de-mosaic the resulting image, make out the right colors, and give you as accurate a color reproduction as they can give you. The Foveon sensor didn’t have to do all that complicated stuff. Supposedly, it already knew which color belonged at each pixel, because it captured said color from the get-go. Wasn’t that an amazing capability?

Look what’s happened in the 3½ years since I wrote about the SD14… Sigma launched the SD15 only a few months ago, and guess what its resolution is? It’s the same 14 megapixels if you play their multiplication game or 5 megapixels if you go by the book. Sure, they upped the ISO sensitivity to 1600 from 800 (3200 in extended mode), which is okay, but the AF is slow and the max shutter speed is still only 1/4000 sec when other cameras in the same category offer 1/8000 sec. And there’s no video, HD or otherwise.

In case you aren’t already thinking it, let me sum it up for you: Sigma’s product offerings have fallen behind the times by at least a couple of years, if not more. Some might say they came out with the DP1 and the DP2, and those cameras are interesting in their niches of the market, but they still offer subpar performance in low light and they still don’t record video (unless you count tiny 320×240 video as real video).

I’d like to ask the folks at Sigma this question: What have you been doing these last few years? You had an amazing sensor in your hands, but you didn’t develop it while others took their Bayer pattern sensors to incredible heights of performance. Your Foveon sensor ought to develop 14 or 16 real megapixels now, on each of its three layers. It should go to 6400 ISO or 12800 ISO natively. Then it’d be competitive in today’s marketplace. Instead, it’s the same sensor I saw more than three years ago, installed in a new camera body.

 

In early 2007, FujiFilm also launched a new DSLR. That camera was pretty amazing in its own right, like the SD14, except the FujiFilm FinePix S5 Pro actually met the demands of the marketplace of its time.

It had a wonderful resolution of 12.34 megapixels, an 11-point, 7-area AF system, a 14-bit A/D converter (most DSLRs at the time were still at 12-bit), ISO sensitivity that went all the way up to 3200 ISO natively, and 1/8000 sec max shutter speed.

Most of all, it had a revolutionary sensor developed in-house by FujiFilm. Here’s what they said about it in the S5 Pro press release:

“Fujifilm’s Super CCD SR II will be updated to the new Super CCD SR Pro. Using a unique layout of twelve million paired photodiodes (6.17 million larger ‘S’ photodiodes for main image information, combined with 6.17 million smaller ‘R’ photodiodes for bright area information), the S5 Pro will deliver improvements in noise, dynamic range, colour and tonality. Further improving the capability of the sensor, a new, improved low-pass filter will ensure that moiré and noise are kept to an absolute minimum. Fujifilm believes improvements in these key areas will be of more true value to professional photographers – the challenge is quality of information, not quantity of information.”

In layman’s terms, it had both large and small photodiodes, clustered together in a beautiful geometric pattern, to capture as much image information as a single-layer sensor could capture, and a powerful engine to analyze that information and turn it into beautiful photographs.

People who used the S5 Pro loved its image quality. And even now (in 2010) when you look on Flickr you see that people are using it and the quality of the images they post very good.

So what has happened since 2007? It looks like FujiFilm dropped out of the DSLR market altogether. The S5 Pro is listed as discontinued on their website and there’s no other model to take its place. None. Instead, FujiFilm is focusing on regular digicams, and seems to be leaning toward cameras that exploit the higher end of the focal range (15-30x zooms).That’s a losing battle as far as I’m concerned. High zooms suffer by default of aberration and other artifacts as one gets above 15x. And in order to get the proper magnification in a smaller camera body, the sensor needs to be made really small — so small that you run into significant noise issues and photo quality suffers even at low ISO and at close range.

What FujiFilm did makes no sense to me. They have incredible know-how in the production of professional, high quality lenses. Their Fujinon lenses are used in satellites, in high end telescopes and in broadcast-quality TV cameras and camcorders. They have the know-how to design really nice camera bodies. I used the FinePix S9100 and I loved its body design. And you only need to look at their current digicam models (S200EXR or HS10), at they way the controls are positioned and the grips are designed, to realize that Fuji knows a lot about camera body design.

When it came to digicam design, they also had what was a big plus over other camera manufacturers. Most of their zoom cameras had manual zoom and focus, and the ability to use regular AA batteries. A manual zoom is just nicer than a servo zoom. It’s more responsive, more controllable, doesn’t eat into the battery life, and it’s more reliable over time. And isn’t it nice when you’re in the field and your camera runs out of juice, that you can just pop in a couple of AA batteries and keep on going? That’s such a practical design aspect, but people tend to forget it when they focus purely on battery life.

Now you look at their line-up, and only two cameras still offer manual zoom: the S200EXR which B&H Photo says was discontinued by the manufacturer even though it’s still listed as an active camera on the FujiFilm website, and the HS10. The rest all offer electronic zooms, which I don’t like.

Keep in mind all the good things I told you about FujiFilm’s know-how, and let’s look at the S5 Pro again. The sensor and the engine was clearly Fuji’s. But the body design was similar to Nikon’s body design. The camera was made to work with Nikon’s lenses. It’s as if FujiFilm didn’t want to own the very camera it made, the camera which contained its revolutionary sensor. This makes no sense to me. They knew how to make fantastic lenses, but didn’t make them for their own flagship DSLR. They knew how to make fantastic camera bodies, but didn’t make one for their own flagship DSLR. Does that make sense to you?

I wrote to FujiFilm PR in January and March of 2007, asking for a review unit. They were willing to send me one, but they didn’t have any lenses to loan me. I needed to supply my own Nikon lenses for the camera, and since all my equipment was Canon, that was no good. I gave up on reviewing the camera. And I bet you I wasn’t the only reviewer who would have liked to write about the S5 Pro but was turned off by the lens issue.

I’m really sorry to see that today, FujiFilm isn’t even developing their revolutionary sensor any more. Sure, they’re using a variant of it in some of their point-and-shoots, but that’s like saying your lawnmower has a Lamborghini engine inside. You can’t get the performance of a true Lamborghini engine from a tiny, cramped 2-cycle engine made to cut grass, and in much the same way, one can’t expect to get the true performance of the large sensor found in the S5 Pro from a tiny 1/1.6-inch sensor.

Don’t tell me CCD sensors are inferior to CMOS. They each have their pluses and minuses. CMOS sensors were thought to be inferior to CCD just a few years ago, but there was a real R&D push to make them better, and look at them today — they’re incredibly good. Don’t tell me you can’t get great video from CCD sensors. Professional camcorders use either CMOS or CCD sensors to record full HD video, depending on the model and brand, so I know that’s possible.

I know that with continued R&D effort, both the Super CCD SR Pro sensor and the Foveon X3 sensor could have been improved greatly, making them competitive and even dominant by today’s standards.

I feel bad for FujiFilm and for Sigma. Perhaps FujiFilm feels the market is already too competitive and has enough business from its other sectors. And it could be that Sigma is focused on its lenses and is satisfied with only a niche of the DSLR market. I don’t know, but I would like to find out more. If anyone has any additional information, please chime in.
