Nicholas A Micros Posted April 7, 2010 Share Posted April 7, 2010 I need help finding my CoC with an odd medium. Shooting 1920x1080 with a 1/2 sensor (EX3 6.4mmX4.8mm) and the film is intended to screen on an 30' - 60' projector. There is not an sure answer for uprez. So I want to play it safe and say 4k. Giving the frame a 2.8444 magnification. Thanks Link to comment Share on other sites More sharing options...
Premium Member John Sprung Posted April 7, 2010 Premium Member Share Posted April 7, 2010 This is a case where theory math are probably going to be a waste of time. There are too many variables. You'd do better to shoot a diagonal newspaper test, and pick your circle size based on that. To calculate DOF tables with the circle of your choice, try this spreadsheet: http://www.auner.net/misc/DOF/DOF.xls -- J.S. Link to comment Share on other sites More sharing options...
