Older Sigma lenses that were designed for Canon EOS film cameras often don’t work correctly when mounted onto a new EOS digital SLR, even though the newer bodies still use Canon’s EF mount. If you’re an owner of such a lens, you might have heard that you can send it in to Sigma’s service center for them to rechip it in order to make it compatible again.
Did you know that those of you who are handy with electronics can actually do the rechipping yourself at home? Photographer Martin Melchior recently did this with his Sigma 70-210 f/2.8 APO lens, and says that anyone with basic soldering skills can do the same.
Want to create a long exposure photo but don’t have a camera that can keep its shutter open for extended periods of time? Mansour Moufid of Elite Raspberries is working on a script called “Hipshot” that can take ordinary video footage and convert it into a faked long exposure still photo. He writes,
Long-exposure photography is a technique to capture dynamic scenes, which produces a contrast between its static and moving elements. Those parts of the scene which were in motion will appear blurred, creating a nice effect.
[Above] is a long-exposure shot of a stream I took recently. It is technically not a long-exposure photograph, but a simulation; this image was actually generated from a video recording taken with an old iPod, which was then processed in software into a single image. (Forgive the poor quality, I don’t own a good camera. Nonetheless, this image demonstrates the desired effect.)
You can check out the technical details of how the Python script works here. If you want to try it out for yourself, you can download Hipshot over on Google Code.

Yesterday I wrote a post showing the high level of image quality you can achieve by scanning film using a digital camera rather than a film scanner. This post will describe my personal technique for digitizing film using a DSLR and a macro lens.
Wet plate photographer Ian Ruhter has received a good deal of attention over the past year for using a custom camera van to create giant collodion process metal photos. When he’s not turning large sheets of metal into photographs, he’s sometimes working on the opposite side of the spectrum.
One of his recent interests has been shooting pint-sized photos using a Holga toy camera that he converted into a wet plate camera.
If you have an old plastic kit lenses lying around, something that you are not using for anything serious, you can give it a new life as a macro lens by removing the front element.
Have an old Polaroid camera lying around collecting dust? Did you know that you can use it for wet plate collodion photography? AlternativePhotography writes,
Most collodion photographers are using dedicated wet plate cameras, because wet plates are not nice to put into any ordinary modern cameras. There are instructions on how to use some normal medium and large format film cameras in the wet plate process. Most modern large format cameras are readily usable; only a special wet plate holder is needed. The drawback is the silver nitrate, possibly dripping from the holder inside the camera and eventually ruining it.
There are, however, certain types of cameras that you can use as is, without any modifications. Polaroid 100 – 400 series cameras were designed for Polaroid instant pack film, and the empty film holder can be converted to an excellent wet plate holder.
Once your film holder is modified to hold wet plates, you’ll also need to give the camera a makeshift “bulb mode” by covering its ‘Electric Eye’ light meter with black tape. The tutorial also discusses how you can expose wet plates using an enlarger and/or digitally printed film.

Digital view cameras can be quite pricey, but if you have an old analog view camera and a DSLR sitting around, you can combine the two cameras to make a DIY frankencam. Northlight Images has a tutorial for doing this with Canon DSLRs, and Nikon Rumors has a tutorial for Nikon shooters (either tutorial should work for you regardless of which brand you use). The resulting rig allows you to take advantage of the tilt and shift features of view cameras.
For those of you amateur photographers out there who like shooting film, sometimes old cameras don’t have the right light meter for getting the correct exposure. Sometimes they are faulty, inaccurate or have no light meter at all! Photographic light meters can be pretty expensive but analog foot-candle meters are cheap because they don’t really have any photography purpose, until now. This guide will show you how to put it to work for photography.
Camera bags can get pricy, and when it comes to camera bags that travel well (i.e. on wheels) prices can really skyrocket. In fact, if you type “Rolling Camera Bag” into Amazon your first three options will run you $262.54, $171.07, and $249.00.
So if your idea of prepping for a vacation with your camera doesn’t include a hefty bag budget, Jerrit Pruyn over at FStoppers has a great solution: take your ordinary rolling carry-on bag, buy a matching Calumet Padded Insert for about $30, and put the two together. The result is pretty indistinguishable from some of the rolling camera bags you’ll find on the market.

If you have an old mount for attaching a GPS or cell phone to your windshield, you can upcycle it into a suction cup tripod for your camera (just make sure it’s not the flimsy kind that falls off on its own). What you’ll need to do is flatten the mount surface and then install a tripod screw. Nano_Burger has a step-by-step tutorial on how he did this conversion over on Instructables. The resulting tripod allows you to fix your camera in locations that aren’t accessible to tripods that don’t suck (hah, get it?).
