So, I'm a bit lazy, having a hand held viewfinder with lines for composition without beating the tripod and camera silly just seems like a good ides. So, and the analog component of the post is an old Nikon F and a 4x5 Linholf, but I just picked up an app for my android phone, the Artemis Director's Viewfinder.

Anyone have any other apps like it that you use, and any comments would really be appreciated. (or even setups for various large format lenses).
