One of the problems with film as compared to digital photography is that you have to keep forking out funds for film and processing. Lomography's color negative film, however, is extremely cheap and surprisingly pretty good. It can't compete with something like Portra in terms of consistency or color accuracy, but I have found it to be better than the drugstore stuff.
It becomes even more of a deal if you're using a Lomo camera. For those who might be unfamiliar, Lomography involves shooting with eccentric or toy cameras, which often introduce elements of unpredictability into the shooting process. Things like light leaks and plastic lenses that love to flare often don't look much better on expensive film than they do on the cheap stuff.
Plus, Lomography is a cool company, so supporting them is a good thing.{C}
