It seems like the physics of silicon long ago replaced the chemistry of silver as the primary means of creating photographs, to the point where few of us even have film cameras anymore, and home darkrooms are a relic of the deep past. Nobody doubts that the ability to snap a quick photo or even to create a work of photographic genius with a tiny device that fits in your pocket is a wonder of the world, but still, digital photographs can lack some of the soul of film photography.
Recapturing the look of old school photography is a passion for a relatively small group of dedicated photographers, who ply their craft with equipment and chemistries that haven’t been in widespread use for a hundred years. The tools of this specialty trade are hard to come by commercially, so practitioners of alternate photographic processes are by definition hackers, making current equipment bend to the old ways. Pierre-Loup is one such artist, working with collodion plates, hacked large-format cameras, pinholes camera, and chemicals and processes galore – anything that lets him capture a unique image. His photographs are eerie, with analog imperfections that Photoshop would have a hard time creating.
Join us as Pierre-Loup takes us on a tour through the world of alternative photography. We’ll look at the different chemistries used in alternative photography, the reasons why anyone would want to try it, and the equipment needed to pull it off. Photography was always a hack, until it wasn’t; Pierre-Loup will show us how he’s trying to put some soul back into it.

When you hear the term “extension tube”, you probably think of something fairly long, right? But when [Loudifier] needed an extension tube to do extreme close-ups with a wide-angle lens on a Canon EF-M camera, it needed to be small…really small. The final 3D printed extension provides an adjustable length between 0 and 10 millimeters.
But it’s not just an extension tube, that would be too easy. According to [Loudifier], the ideal extension distance would be somewhere around 3 mm, but unfortunately the mounting bayonet for an EF-M lens is a little over 5 mm. To get around this, the extension tube also adapts to an EF/EF-S lens, which has a shorter mount and allows bringing it in closer than would be physically possible under otherwise.
[Loudifier] says the addition of electrical connections between the camera and the lens (for functions like auto focus) would be ideal, but the logistics of pulling that off are a bit daunting. For now, the most reasonable upgrades on the horizon are the addition of some colored dots on the outside to help align the camera, adapter, and lens. As the STLs and Fusion design file are released under the Creative Commons, perhaps the community will even take on the challenge of adapting it to other lens types.
High resolution digital cameras are built into half of the devices we own (whether we want them or not), so why is it still so hard to find good pictures of all the incredible projects our readers are working on? In the recently concluded Beautiful Hardware Contest, we challenged you to take your project photography to the next level. Rather than being an afterthought, this time the pictures would take center stage. Ranging from creative images of personal projects to new ways of looking at existing pieces of hardware, the 100+ entries we received for this contest proved that there’s more beauty in a hacker’s parts bin than most of them probably realize.
As always, it was a struggle to narrow down all the fantastic entries to just a handful of winners. But without further adieu, let’s take a look at the photos that we think truly blurred the line between workbench and work of art:
[Cole Price] describes himself as a photographer and a space nerd. We’ll give that to him since his web site clearly shows a love of cameras and a love of the NASA programs from the 1960s. [Cole] has painstakingly made replicas of cameras used in the space program including a Hasselblad 500C used on a Mercury flight and another Hasselblad used during Apollo 11. His work is on display in several venues — for example, the 500C is in the Carl Zeiss headquarters building.
[Cole’s] only made a detailed post about 500C and a teaser about the Apollo 11 camera. However, there’s a lot of detail about what NASA — and an RCA technician named [Red Williams] — did to get the camera space-ready.
If you’ve ever tried to take a picture of a fast moving object, you know how important timing is. You might only have one chance, and if you hit the shutter a bit too early or too late, the shot could be ruined. Past a certain point, no human camera operator can react quickly enough. Which is exactly why [Krzysztof Krześlak] created PiXPi.
In the past we’ve seen high-speed flashes designed to “freeze time” by illuminating the scene at the precise moment, and while PiXPi can technically do that, it also offers a few alternate methods of capturing that perfect moment. The idea here is to give the photographer the best chance of getting the shot they’re after by offering them as many tools as possible.
Essentially, PiXPi is a microcontroller that allows you to orchestrate your DSLR’s trigger, external flashes, and various other sensors and devices using an easy to use graphical programming interface from your smartphone. So for example, you could program the PiXPi to trigger your camera when it detected a loud enough noise.
But the device also allows you to be a bit more proactive. Rather than sitting back and waiting for a signal to fire off the camera, the PiXPi can directly take control of the action. As an example, [Krzysztof] has created an electronically triggered valve which can release a drop of liquid on command. Using PiXPi, the photographer can quickly put together a routine that triggers a drop, waits the few milliseconds it takes for it to hit the target, and then snaps a picture.
The goal of the 2019 Hackaday Prize is to develop a product fit for production, and naturally a huge part of that is having a well thought-out design. But if you’re ultimately looking to sell said product, it’s also very important to keep the needs of the end user in mind. To that end, we think [Krzysztof] has done a great job by not only making the system very flexible, but keeping it easy to use.
Even a relatively low-end desktop 3D printer will have no problems running off custom enclosures or parts for your latest project, and for many, that’s more than worth the cost of admission. But if you’re willing to put in the time and effort to become proficient with necessary CAD tools, even a basic 3D printer is capable of producing complex gadgets and mechanisms which would be extremely time consuming or difficult to produce with traditional manufacturing techniques.
Once you find yourself at this stage of your 3D printing career, there’s something of a fork in the road. The most common path is to design parts which are printed and then assembled with glue or standard fasteners. This is certainly the easiest way forward, and lets you use printed parts in a way that’s very familiar. It can also be advantageous if you’re looking to meld your own printed parts with existing hardware.
The other option is to fully embrace the unique capabilities of 3D printing. Forget about nuts and bolts, and instead design assemblies which snap-fit together. Start using more organic shapes and curves. Understand that objects are no longer limited to simple solids, and can have their own complex internal geometries. Does a hinge really need to be two separate pieces linked with a pin, or could you achieve the desired action by capturing one printed part inside of another?
If you’re willing to take this path less traveled, you may one day find yourself creating designs such as this fully 3D printed turntable by Brian Brocken. Intended for photographing or 3D scanning small objects without breaking the bank, the design doesn’t use ball bearings, screws, or even glue. Every single component is printed and fits together with either friction or integrated locking features. This is a functional device that can be printed and put to use anywhere, at any time. You could print one of these on the International Space Station and not have to wait on an order from McMaster-Carr to finish it.
With such a clever design, I couldn’t help but take a closer look at how it works, how it prints, and perhaps even some ways it could be adapted or refined going forward.
Although Iceland is now a popular destination for the day-tripping selfie-seeking Instagrammer who rents a 4×4, drives it off road onto delicate ecosystems and then videos the ensuing rescue when the cops arrive, there are still some genuine photographers prepared to put a huge amount of time and effort into their art. [Dheera Venkatraman] is one of the latter and produces composite photos using a relatively low resolution thermal camera and DIY pan and tilt rig.
Whilst we don’t have the exact details, we think that, since the Seek Reveal Pro camera used has a resolution of 320 x 240, [Dheera] would have had to take at least 20 photos for each panoramic shot. In post processing, the shots were meticulously recombined into stunning landscape photos which are a real inspiration to anybody interested in photography.
If you do go to Iceland you might find the traditional food a little challenging to those not raised upon it, nor would you go there for a stag night as beer is eyewateringly expensive. But if you enjoy uninhabitable, desolate, dramatic landscapes there is a huge range of possibilities for the photographer from rugged, frozen lava flows to extra terrestrial ‘Martian’ crater-scapes, if you know where to find them.
