Finally an app for for AC's and other filmmakers to stop wasting time with paper camera logs. No-one reads them anyway if they have 100's of paper logs to sort through. Use this app and get rid of all that paper waste and make it easy to share these logs with the whole camera team and any producer, editor, director, and of course DP. Also stop refilling the same info over and over again, the app fills out the generic info for you right away, you just fill it out for one log only once, and it recalls it for you each subsequent log and increments the Take field for you as well. Any field you want to change just change and it will be remembered again for the next log. When your all done with the day, just email the logs to the producer. Its as simple as that. The app also allows you to hide fields you don't want to see. So its very flexible for every filmmaker. Email us if you want to see something else that would be useful to you as well.
