Photographer Maciej Pietuszynski has posted a (hopefully tongue-in-cheek) step-by-step tutorial over on his blog on how he was able to give his Canon 40D a square aspect ratio viewfinder by applying some tape to his focusing screen.
It could be a funny prank for convincing people that you have some kind of special, limited-edition DSLR, but be warned: focusing screens are extremely susceptible to dust and scratches. Unless you want to risk messing up the viewfinder of your camera, you might want to refrain from doing this mod yourself.

Here’s a primer for beginning photographers on the concepts of aspect ratios and compositional theories.
Ever wonder why most DSLR cameras capture images with a 3:2 aspect ratio, while most other cameras use 4:3? It’s because they were designed to match different things:
Common aspect ratios in still photography include 4:3 (1.33) used by most digital point-and-shoot cameras, Four Thirds system cameras and medium format 645 cameras; 3:2 (1.5) used by 35 mm film, APS-C (“classic” mode) and most DSLRs;
[...] The reason for DSLR image sensors being the flatter 3:2 versus the taller point-and-shoot 4:3 is that DSLRs were designed to match the legacy 35 mm SLR film, whereas the majority of digital cameras were designed to match the predominant computer displays of the time, with VGA, SVGA, XGA and UXGA all being 4:3.

Prints have been around longer than digital cameras, so that’s why your compact camera photos are cropped when you try to have them printed as standard 4×6 prints (4×6 prints have an aspect ratio of 3:2).

Canon may have revealed its plans for the Wonder Camera yesterday, but Olympus also quietly released something of its own to marvel at.
According to a newly published Olympus patent, originally filed in 2004, a new camera may be in development that is designed to make consumer point-and-shoots even more intuitive for casual photographers.
