You don't mention what format you shoot, but I think the large formats can be very restrictive for many people. It is a rare photographer who can compose ULF with the skill of a Kenro Izu; most ULF shooters, I think, "why bother?"

Medium format and smaller can be very liberating, allowing you a lot more room just to play and see the world without every frame having to be a masterpiece. Changing formats can have an extremely refreshing effect on your vision.
