It’s surprising how often a brilliant idea is missed out on until years after the fact. In this case the concept was seen publicly within ten years, but the brilliance of the inventor has been appreciated once again after 110 years. It’s a color movie which was filmed around 1901 or 1902 but it sounds like the reel wasn’t shown in its full color grandeur until 2012 when the National Media Museum in the UK started looking into the history of one particular film.
The story is well told by the curators in this video which is also embedded after the break. The reel has been in their collection for years. It’s black and white film that’s labeled as color. It just needed a clever and curious team to put three frames together with the help of color filters. It seems that [Edward Turner] patented a process in 1899 which used red, green, and blue filters to capture consecutive frames of film. The patent description helped researchers put image those frames — also using filters — to produce full color images like the one seen above.
The press release on the project shares a bit more information, like how they determined the age of the film using genealogical research and the fact that [Turner] himself died in 1904. The process didn’t die with him, but actual evolved and was exhibited publicly in 1909. This, however, is the oldest known color movie ever found.

With digital cameras in everything and film slowly disappearing from shelves, everyone loses an awesome way to learn about photography. Pinhole cameras allow anyone to build a camera from scratch and also learn about those crazy f-stops, exposure times, and focal planes that Instagram just won’t teach you. [Matt] put up a great tutorial for building your own pinhole camera, and the project looks easy enough for even those who are still playing around with their cell phone cameras.
For film, [Matt] used 120 film, a medium-format medium that is sill available for purchase and processing in some areas. Because [Matt]’s pinhole is relatively large and made out of very thin material, the camera could take very large pictures – much larger than standard 35mm fare. If you’re using a smaller camera projecting a smaller image onto the film, 35mm would be the way to go as it greatly decreases the difficulty of finding film and a processing center.
[Matt]’s camera is constructed out of laser-cut plywood. Because he’s producing extremely wide images with his camera (6 x 17cm), [Matt] needed to curve the film around the focal plane of the camera to keep the entire image in focus.
The mechanics of the camera are simple – just a pair of knobs to wind the film and a small metal shutter. [Matt] added a shutter release cable to open and close the aperture without moving the camera and had a wonderful camera perfect for capturing either sirs and madams or Civil War battlefields.
A little bit of technology goes a long way when it comes to stop motion animation. In this case it’s a trio of simple camera dollies built during production of a short film called The Maker.
A Dolly is a method of mounting the camera so that it can be moved smoothly during a shot. Of course with stop motion the movement actually happens between the shots so it’s even more important that the camera be moved accurately. The video after the break shows off how they added CNC control for the camera. The first dolly was built from a pair of PVC pipes with a sled that moves along them. A motor moves a loop of 35mm film which is attached to the dolly. This is a great choice of materials since it doesn’t stretch and it’s free (one of the filmmakers is a projectionist). The next dolly is made from a flatbed scanner, and the final offering is seen above. Built from a bicycle wheel it provides a stationary platform above the hub for the models, while the camera rotates on an arm attached to the wheel. You can watch the complete film here.

This beautifully crafted device is a timer used for getting the perfect exposure when making film prints of photos. But in addition to keeping time, it also does logarithmic calculations that are based on the f-stop values used for each exposure. It does this in 1/100th of a stop increments. While he was at it, [William] also decided to pack in a bunch of other features like dry down correction, and support for making test strips. This is a little hard to understand when discussed in the abstract, but just take a look at his video after the break where [William] walks us through an example exposure and all will become clear.
You can see from the construction page that the device is basically an Arduino shield. It provides a relay for controlling the exposure lamp, a keypad, rotary encoder, and character LCD. Slap it in a fancy case, connect it to the equipment you’re using, and you’ll be creating perfect prints in no time flat!

This flimsy case isn’t going to protect your Raspberry Pi if you knock it off the workbench. It will provide a level of protection against shorting out from contact with metal objects, or from liquids spilled in the near vicinity. [CGPatterson] ended up making this case from a single sheet of transparency film.
The project is basically papercraft. He started with the dimensions published on the Raspberry Pi FAQ, which turned out to be wrong. Not having a caliper available to help with the precision of the measurements, he grabbed his ruler and did the best he could. The first two cases were a poor fit, but as you can see the third is like a glove. Luckily you don’t have to go through this same trial and error as he release the design. Both A4 and US Letter sized PDFs are available for download. Print them out on the transparency, cut along the lines, apply transparent double-sided tape to the tabs and you’re in business. If you wish to alter the design he has also posted the SVG source he made in Inkscape.
This is certainly a good option for those of us without the ability to produce laser cut parts.
A picture’s worth a thousand words so what is a hat that can take 360 degree pictures worth? Just make sure you put it on whenever leaving the house and capturing that next memorable moment will be just one click of a button away.
[Mikeasaurus] recently put together this… special… headgear. He used film-based disposable cameras and this choice presented a few interesting challenges. But the choice is not necessarily a bad one, as you can get six of these without really blowing your budget. He cut the top off of a plastic garbage can to serve as a headband on which to mount the hardware (zip-ties to the rescue). But things get hairy when it comes to triggering all of the shutters at once. These are spring-loaded shutter releases and you can’t just patch into them electrically like you could a digital camera. His solution is a group of six servo motors which do the button pushing for him.
A thirty-six exposure trial run turned out okay. Several times the shots didn’t come out, but at the end of his post he shares a few of the good ones that did. We’re going to stear clear of this one as we can’t abide manually winding all six cameras between each shot. But it does give us an idea for a single-camera hat that uses a 45-degree mirror which swivels. We’ll just put that one in the growing pile of ideas we need to make time for.
For camera fanatics the acquisition of an old camera is a thrilling event. But if you’re going to collect them, you’d better have some repair skills so that you can also use them. [Fernando’s] latest find was this Minox 35mm camera. The aperture needed cleaning, and after reassembling the unit he realized the he had not marked the focus ring when taking it apart. This is not a reflex camera, so you can’t look in the view finder to adjust focus. He came up with his own method to get the focus ring calibrated.
The focal point needs to focus on the film. He simulated this plane using some magic tape, which removes easily without leaving a residue. When the shutter is open, you can see the image projected on this translucent surface. He then set up the camera with the lens 90 cm from a bright light bulb. By adjusting the focus to create a sharp image on the temporary screen, he knows the focus is calibrated, and can reset the focus ring to the 0.9m mark.
