What's funny, is that you can practice "lomography" with any camera.
Sometimes I do it with my Rolleiflex, sometimes I do it with my Hasselblad.
I even do it with my Leica, Nikons, and Pentax 6x7 occasionally. Lomography is simply the overcoming of obsession with technical limitations and theory, and just giving plain old serendipity a chance.
Sometimes I shoot my 6x7 without the lens mounted, just held in front of the mount, so that I can tilt and shift as I please. A shroud of black duct tape is a serviceable enough bellows. That's pretty f*cking lomo, if you ask me.
