Photoshop’s Content Aware Scale tool doesn’t get much headline time thanks to other popular features like Content Aware Move and, of course, the vilified Liquify tool, but it can come in extremely handy in a few situations. Read more…

When it comes to the type of glass used in still photography, versus the glass used in motion picture, there’s quite a dramatic difference in design, quality and price. Quite often, it’s the last of those differences that is the most inhibiting for photogs who want to dabble around in motion picture.
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.)

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.
