Hi there... and good evening... humm... i'm workintg on a Palm Proggy that keeps track for you of these infos. It's a very easy to use database that syncronize himself with your desktop computer. Maybe if someone is interested i could use the community for beta-testing. Works on Mac and PC and under PalmOS or PocketPC platforms. so everytime you are outside you can record every single aspect of your shots and films in real-time. Keeps track of all your data to remember when you work with the Zonal System.
