I find the holga to be a tool to use when a "distorted" or "dreamy" look seems suitable. I find it very useful for old things, especially buildings. Industrial subjects work great too. When printing, using heavy sepia toning or lith printing can result in beautiful prints. Alot of times I'll throw my holga in my bag along with my Mamiya 6 (real camera) and Bronica RF645 (also real camera... haha) and then I have a nice 3 medium format camera system all in one bag. Adding the holga doesn't add any weight either! Take it along more often and you'll find subjects that just scream HOLGA!
