Homemade Digital Cameras
Michael Golembewski writes "For the past three years, I've been taking apart cheap secondhand flatbed scanners and turning them into homemade large format digital cameras. They are well over 100 mexapixel in resolution, and produce results that are both similar to and significantly different from traditional digital and conventional cameras."
That is some eerie art! Is your initial part of your last name really pronounced "Golem" by chance?
Very cool effects. When I read the snippet I figured this was going to be something like the old "Make an E-size scanner out of any hand scanner" fraud that was popular for a few years back in the old days (remember stitching manually on a Pentium 200, anyone?).
For some reason I can't believe this works. I figured the scanning element (CCD) needed an intense amount of light to properly "read" an image on the bed.
The fact that you use duct tape to get everything "light tight" put a good smile on my face, as well as the fact that you even got this working. If you're thinking of selling artwork, I'll be the first in line (the lady and I realized it's time for more photo-prints in the house). By the way, the image taken of the actual camera doesn't seem very high res. Was this by choice?
While it's a neat (if not original) hack, why bother making actual photographs with it? The point of large format digital is very high quality, and it doesn't look like you're getting that.
If it's the look and effect you are going for, you can achieve that more easily with a regular digital camera and a bit of post-processing.
Well, well. Since the quality exceeds those provided by "consumer-level" equipment, how are these guys going to deal with the Digital Transition Content Security Act?

This has got to be one of the more fun geek mod projects. I'm definately assembling one. Got to keep an eye out on Ebay for a suitable camera. A great new use for my notebook. I'd love to try some shots at a carnivale. The spinning rides would make for some interesting shots. I'd love to try some high res landscapes though. Could also do some stunning macro photography as well.

Disable the motor (maybe just remove the carriage), and set it up to take pictures of things going past it. Cameras like this are used at finish lines at athletic meets. Interesting distortion. Might be an interesting project for someone still at school - I was once around the teachers trying to work out who won a 100m dash: some of them were a little bald(er) by the end of the day.

What a great idea. It reminds me of when I got my first scanner and I'd scan my face, following the light down as it passed my eyes or mouth, which created some very Blackhole Sun video type images. I can't decide if the details he gives on how to make the camera aren't detailed enough because a) I just haven't played with it enough to see that it is self explanatory or b) because it really isn't detailed enough. I can't tell if this is a really old school camera obscura type hack that would require moving parts or if it just focuses the image small enough onto the CCD (or whatever the proper TLA is) that it doesn't have to move. I'm guessing moving parts since the cameras are so big. I need to watch eBay for a cheap scanner. This would be fun to play around with.
This is kinda similar to the technology they use for doing photo-finishes in track & field races.

It seems he figured out how to script the camera to take continuous photos, and animated them into movies. Unfortunately, these movies require Flash 8 to play, and the latest Linux Flash Player is v7! This is the second site today that has kept me from viewing content because of this issue (though in this case it simply seems inadvertent; by contrast, you can't access any of animationmentor.com with Linux).
That's the kind of thing that makes you wish you'd thought of it first. =)
Those pictures are amazingly one-of-a-kind.
I'm sorry. The number you have reached is imaginary. Please rotate your phone 90 degrees and try again.
I find it hard to believe that he can get 115 megapixels out of that scanner. Since he is using a 4x5 camera, that works out to a scanner resolution of 2400dpi. That is the kind of resolution of high-end film scanners, not a cheap flatbed (whatever the marketing material says).
lhk
Nice. My first thought was that it would be just one of the many how-to-make-your-own-digital-camera articles that have been around for ages at Make magazine and other similar media... so a lot nicer and more creative than that. And now I want to find an old, old camera, with an old flatbed scanner and try some of that stuff myself.
Back in the early 90's Dicomed introduced a digital camera back for 4x5 cameras for commercial use. It used the same theory, slap a scanner on the back of the camera. You had to use hot lamps, a studio environment and nothing could move. But the results were stunning, 100MB files that could easily be printed on the cover of a 150 line screen magazine. Wonderful.. What is really cool about your work is that you are celebrating all of the motion artifacts that studios were killing themselves to remove when using this technology. Your stuff is pretty creative and fun, and most importantly makes one look at the world differently.
Interesting project, it reminds me of the digital camera I built with a fellow student as a degree project. We ground the top of a 256 byte DRAM using a grinding machine in the mech.eng lab and fitted a glass window. The DRAM capacitors discharge at a different rate when exposed to light. We mounted the chip to a PCB, cut the back out of a 35mm Zenith camera and mounted the PCB. Obviously the optics and chip were poorly matched, we were only using a small part of the lens.
Knowing the discharge rate of the DRAM and the time to load and scan all 256 elements you could get a black and white image. We used the camera for some image recognition work. One application was counting the number of cups remaining in a drinks machine hopper by edge detecting the image then counting the "lips" that we saw.
That was back in the autumn of 1986. We've come a long way.
The scanner software that comes with the scanner he's presently using shuts the thing down if there are hardware faults. All his mods count as hardware faults thus making the shipped driver useless to him. He discusses a closed source pro driver which is a bit better, but still not perfect for his needs. Then explains how he uses SANE to make the thing actually work like he wants.
That's cool -- an artist embarks on getting enough programming language to modify a program so he can use it like he wants to. That's owning your hardware in the purest sense. And it's made possible by the community that generates all that great open source software.

Excellent work! You've created something 'original' and as well, replicating some of the effects of distorted paintings of the 18th century.
Technically you've cobbled together some cheap equipment to produce interesting timeslices of reality.
I was thinking that the lenses you have used should create a focused image on the glass? If so, does the image cover the whole area of the glass or just a portion of it?
Is the focussed image large (A4 size for eample)?
What if you use the scanning engine from a slide scanner? This way the scanner-camera would be physically much smaller and yet achieve comparable resolution? (and would probably scan faster when required).
Brilliant work!
Don't be apathetic. Procrastinate!

I'm sure he already knew how to code. He probably just learned the new syntax/language specific to the project. I took 2 years of coding, and there's no way I learned enough to be doing what he did.
Is well known - it happens with focal plane shutters.
Much less pronounced of course since an FP scans a
little faster.
Looks like the guy in the article takes it to a new level, but this guy here has been using a scanner as a artistic hand-held photographic device and making some really cool looking images too.
The cameras seem to be put together with nothing but spit and scotch tape, but the results are astonishing. I think I'll go and hack my old Epson scanner now!
You'll find it in Goethe. I can't remember the original word for word, but in effect he says that without working within restrictions we never reach the highest levels of achievement; whoever wants to make something great must submit to the limitations of some medium. This guy has found a restricted medium that can be used to produce something like art. Arguments about megapixels are as irrelevant as arguments about how fine Renaissance artists could grind up their paint.
Pining for the fjords
Putting aside for a moment the artistic effects, this project could be turned in a distortion-free ultra-cheap ultra-hi-res digital camera. You only need to "fix" the image so that it stands still while the scanner works. For example, you could expose to light a plate covered with some photo-sensitive chemical (like, for example, a silver halide) and then putting that in front of the scanner. I wonder why nobody thought of this before...

Don't know about his cat, but Schroedinger is definitely dead.
This seems to be actually repeating early developments in professional digital photography. The first digital backs for cameras like the Sinar, and the Arca Suisse were miniaturized flatbed scanners like that. Obviously they were really good only for still life. But still (back in 1992 or so) when I was in photographers school and we visited someone who had one of those backs, we managed a portrait of someone sitting very still. There were little smears where his breathing caused motion.
Sadly we did not experiment with more motion. I think the "experimenting" with motion is the interesting part (as far as photography is concerned). Some of the pictures on the site are enjoyable. Hacking it all together yourself is interesting too, at least for us geeks.
As for the comments in the style of "large format photography is only about the image quality"... it isn't exactly only about that. It is also about stuff like parallax control (putting buildings "upright" with parallel lines) and depth of field control (laying the plane of the depth of field folded through the scene in order to allow image to be sharp on other areas). All this can theoretically be achieved even with smaller formats, but due to mechanics it gets harder the smaller the format (Arca Suisse's 6x9cm cameras seem to be the smallest that still work very well, at least in my experience).
Therefore the "experiments" done with this hack to in a line a bit with stuff like putting ordinary photographic paper into a large format camera or using polaroids for transfer prints. The "long exposure" part of it is also a reference to the times way back, when due to old processes like the daguerreotype, portrait subjects were held up with wire constructions. Very cool, all of this hack, congratulations.

The frustration occurs in that while the exercise is interesting, the tease of having a 115MP camera for pennies, and be just as easy to use as any digicam you can buy nowadays is not there. His camera is cool, but most of us are better served just plunking down the $200 for a Kodak and start snapping away. Many final usable pictures, not an exploratory quest into hacking, is what the most of us want to accomplish.
Yeah, maybe he should just strap three of these together and post-process in Photoshop.
Well, post-processing actually only works on the image you have in front of you. Given that the scanner exposes individual lines in the image over time (e.g. it - "scans") to generate the end image, you would actually need a movie to be able to generate the same effect with post-processing. A movie with very high-quality frames, and an unbelievably high frame rate (effectively you would want a frame for each line, so depending on the scan speed up to perhaps a few thousand frames a second - and then you would throw out the entire frame except the single line you wanted.) The scanner idea is starting to sound better to me.
On a more general note, this whole attitude is endemic now. Sure you can correct stuff later, but it is generally better in photography to try to get the best image you can at the moment you are taking it; you've then have got a lot more to work with! The phrase "polishing a turd" comes to mind...
This is the first HE hack I've seen on /. that made me go "I wanna do that!". Perhaps it's because photography has become a bigger hobby of mine than computers?

I exaggerated, I only took 3 semesters of C++. Intro, Data Structures, File Structures, and Assembly were the four classes I took. But I was an absolute beginner, I had no years of messing with Basic in High School. I came in with zero knowledge of anything having to do with coding. So with just with this core knowledge, what exactly is the level of code you think I should I be able to crank out? I don't think Linus would be clamoring for my skills anytime soon with this instructional set under my belt.

I remember reading about a similar attempt using EPROMs in late '80s. In a normal recycling procedure, these were erased by shining a high intensity UV light for a couple of minutes through the glass window that's present in the IC shielding. After making sure all bits are reset, the window is covered by a sticker or label. Then the data is 'burned' and the (typically 256Kb/32KB) ROM was inserted into your BBC micro (insert favorite hobby computer).
Similar to the process you describe, an image could be gathered by setting all bits to 1 (or actually 0, as EPROMs have negative logic), then waiting for bits to flip. I don't think a lense was used, just a diafragm (dot in piece of black paper). On average, an exposure took 1-4 hours (and resulted in a very poor quality black/white image for current standards) if the scene was bright enough. Lighting the scene with a UV helped a bit, though visible light worked surprisingly well.
Of course, the whole whing was hardly useful, but remember that - at the time - the average micro had little more periferals than a keyboard, joystick. Mac had a mouse and some MSX systems had support for an analog "gen-locked" camera, BBC had some support for light pens. There may have been handscanners for PC/ATs. So mostly any hardware that would allow translation from analog to digital was greedily welcomed.
I'm tempted to bid... please, somebody, stop me?!!!!

Absolutely fantastic images.
I'm just wondering if you (or anyone else) has considered changing the speed of the scanner motor so you can do long exposure stuff. Capturing a sunset or something running from top to bottom would look absolutely awesome.
However, I guess you'd need to stop down dramatically for something like a 15 minute exposure of the sun...

With that many pictures I would have used the coral cache link in the summary.
You can get a similar effect, at much poorer resolution, by processing digital video of a pan. You take a narrow slice out of each frame, and append them together into a scanned image.
I've played with this and got some images I'm very pleased with. However it's spurred me into wanting to hack some scanner hardware. Unfortunately I'm more comfortable with software than I am with the mechanical...
I wrote up the video to panorama stuff.
A pinhole camera would fit your needs methinks. Just punch a very small hole in a lighttight box and voila there is your camera. But you will have to figure out your own exposure time though.
This space is intentionally staring blankly at you
You have to set the scan area as small as possible.

I once did something similar with a scanner. I needed a close-up shot of a keyboard for use as a splash screen for ergonomic software I was working on. I didn't have a digital camera but I did have a scanner, so I took a keyboard and placed it upside-down on the flatbed and scanned it in. I was a little desperate and did not expect a very good image. But I was amazed at the results. The image was perfect!
large format cameras usually do allow perspective correction & depth of field control, since they usually have a bellows between the lens & film, and both of those can be tilted & shifted: putting the film plane parallel to the from of the building, then shifting the lens to make the image fall back on center...
but t&s is not limited to large & medium format cameras...canon made a t&s lens for its 35mm line.

Camera made from a scanner? Very interesting. But how do you get the subject to mash their face, or other body parts, against the scanning bed? Must be hard to use for group shots. :)
Take a similar device to orbit of Earth (or Mars), and use the scanning technique to artificially enlarge the resolution of images taken by satellites. I think they've done it with some Mars probe, but I'm not sure. I'd like to see the whole of Moon mapped with 5 cm / pixel resolution.
The Martian Rovers and Casini use scanning cameras to reduce weight and volume of optics. Works fine if things arent changing too fast.

I remember seeing a photo-finish for one of the stages during the last Tour de France and they used a similar setup. The image was all normal-looking except for the spokes on the bicycles. Instead of radiating out from the hub to the rim in straight lines, they sort of bent upward. Like so. That's not the best example, but you get the idea.

Used view camera lenses can be had at reasonable prices. There's no good reason not to buy a lens that's a century old. 4x5 inch coverage, even 8x10 are not unreasonable. A look at eBay revealed 2 lenses below $160 for 4x5 coverage. You should be able to buy complete view cameras from an antique dealer.

My wife used to have a jewelry business, and I did all the product photography for her.
At first I tried using film; but the turnaround time, even with 1-hour developing is a drag, because it's tough to get everything Just Right, when you're dealing with highly-reflective and very small objects. So, we discovered that it's much easier to just drop the stuff onto a flatbed scanner and do a hi-res scan. The old HP scanner I had at the time had a really deep depth-of-field and a nice wide, diffused light source, so even non-flat pieces came out very nice. And, you could stick colored paper or cloth on top of the product for fun backgrounds - propped-up a bit if you needed to get the background out of focus.
Then that scanner died and I couldn't find another scanner that would duplicate the DOF and diffused light source. So I bought a digital camera.
But, boring story short: if you can find a scanner with the right DOF, you can do some really great macro stuff with it. 4000dpi at 1:1 shows a surprising amout of fine detail.
I have discovered a truly remarkable proof which this margin is too small to contain.
Sure you can correct stuff later, but it is generally better in photography to try to get the best image you can at the moment you are taking it; you've then have got a lot more to work with! The phrase "polishing a turd" comes to mind...
I would mod parent up, but a) I have no mod points right now and b) it's already at 5.
I saw a ton of this when I worked at Kinko's. People would bring in crappy ripped-up, stained, faded and overexposed wallet photos for enlargement. They didn't want to understand that crappy input like that = crappy output. We could do basic stuff like white correction (one guy liked the white-corrected copy I made for him better than the original photo) and maybe if a customer really begged for it, red-eye editing, but any kind of complicated restoration was beyond us.
But by God, they had seen the whiz-bang scanner commercials on TV! The guy on TV just clicked a button and everything looked brand-new! Why won't you serve me, I'm a customer dammit! What do you mean a 100x50 JPG, won't look good when you blow it up to 60"x30"? (Actually happened. I had to print an 8x10 section of the enlarged image before the guy would believe me when I told him how crappy it would look.)

Seriously, though, this is amazing. The DIY thing is getting a new life, possibly as a result of all this crap that we have laying around that was 1997's big thing.
I picked up a Make mag last week, and recommend it highly. Will I build everything in the book? Hell no, but, it does change one's perspective on what exactly is junk.
Mid-1980s low-rez bw consumer computer-tethered cameras worked the same way.
It was fun to appear on one part of the image, run around the camera, and be scanned a second time.
Look ma, I've got a twin brother!
Interestingly, most 35mm SLR cameras work the same way in high-speed mode:
The shutter in effect has a slit that slides across the film. The speed is way too fast for most artistic use, but you can see it for yourself by taking a flash photo with the film speed set too high - only part of your photo will be "flashed" - the rest wasn't "in the window" until after the flash ended.
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
35mm SLRs have mechanical shutters. Most (not all) work by releasing two curtains in sequence. The first retracts from one side to the other, letting light reach the film. The second extends in the same direction shortly thereafter, covering the film again. What you get, then, especially for short exposures, is a negative which was exposed at different times from one edge to the other. Normally you can't see this effect, but it is possible to capture (or miss, depending on the direction of motion) highspeed events in the field of view.
Essentially the shutter mechanism is acting like a mechanical line-scan.

This kind of distortion is actually not new, it has been known to happen on some traditional film cameras with sliding shutter.
The sliding shutter always moves with the same speed, and high speed (short time) shutter is created by narrowing the openning slit in the shutter that passes in front of the film, usually in horizontal direction. This has exactly the same effect as the scanner, for exactly the same reason. The only difference is that the shutter moves very fast, which makes the effect noticable only when taking picture of very fast moving objects with very fast "shutter speed" (meaning the slit is very narrow). There are some pretty famous shots using this effect.
Cool pictures, though.

...[T]he objects that were moving were twisted and distorted into wonderful shapes. At first, I thought that this was a mistake, that something was wrong with my new contraption. But I soon realized that the motion of the scanner was meshing with the motion of the recorded scene, creating unexpected, yet predictable, results.
Someone needs to tell him that slit-scan photography has already been invented.
Terrorists can attack freedom, but only Congress can destroy it.

He goes through all the trouble of constructing a method for scanning the real world and doesn't even realize the fact that he's going to have an incredibly long, non-uniform exposure? Does he lack a fundamental grasp on how scanners and photography work?

Such high resolution imaging seems to be very suitable for telescopy.
The temporal scanning factor (if highly exaggerated in software) could also be a useful way to observe the effect of earth's rotation on the night sky.
I would also like to see images, scanned vertically, of stationary objects rotating very slowly on a lazy susan.
Many of the low priced scanners will claim a high dpi, but hidden somewhere underneath they then mention it's interpolated. They never mention the true dpi.
