Photographer Maciej Pietuszynski has posted what we desperately hope is a humorous blog post — actually it's hard to tell if it's serious or not — about using tweezers, scissors and tape to give your DSLR a square aspect ratio.
Be warned: it involves removing the (highly delicate) focusing screen, applying tape, and reinserting the thing, all without damaging your precious camera. So probably don't bother. Unless you want to, you know, take cool photos instead of super-serious ones. [maciekpp via Peta Pixel]
