This tool will calculate the depth of field for a given sensor or film type, aperture, focal length, and subject distance (the distance from the camera to the person or object you are focusing on). A lower number means that a large proportion of the background will remain in sharp focus and a higher number means that a smaller proportion (if any) will be in focus.
It also includes presets for popular video cameras. Selecting a preset will automatically change the sensor type to fit your camera.
Please be aware that this tool is designed for cinematographers, not still photographers.
"Pro Filmmaker Apps" is a curated database that can help you get a job done a little better or a little faster. This is a regularly updated resource of hundreds of mobile, tablet, watch, and desktop apps. We only include apps made for and used by film, television, and digital media professionals. Originally on FWDlabs.com — now also at ProFilmmakerApps.com.
"FWD:labs carries the most complete listing of linked professional apps I know besides of the fragmented Android Market (google play) and the iPhone App Store. I suspect it is a tenuous work to compile and link all proven working apps and much more your site offers. I thank you for sharing such complete list of iPhone and android apps for the cinematographer and the entertainment industry in general. I could not pass the opportunity let know my readers about your meticulous resource."FILMCAST
"[R]idiculously useful compendium"Directors Notes
"I thought [FWD:labs] had put together a useful list when I saw it last year, but that was nothing compared to now. If you're a filmmaker and looking for a little portable help in pre/production/post then chances are you'll find it in the [Pro Filmmaker Apps]. I know I can be a little iPhone-centric when it comes to these things, but you’ll be pleased to know the list is completely platform agnostic."Directors Notes
