I’m going to be working as an AC on an upcoming real-film film (more on that later) and decided to bone up. An L.A. cinematographer friend of mine said everyone out there is rocking a palm pilot program that obviates the need for flipping through the fat little book of focus charts. A quick Google search netted me this, which looks great:

David Eubank’s pCam and pCine programs for Palm OS.

It’s offered as shareware, so I’ll pony up if I end up using it. Right now though, it’s fun to play around with.
