Ray Equis Posted July 6, 2014 Share Posted July 6, 2014 When trying to recreate shots for practicing purposes lighting is surely one important part of the equation the other being the lens choice. while lighting schemes and aperture used might be approximated by eye reflections, shadow detail/placement and depth of field, i am wondering if there are any equally useful hints that allow for an educated guess as to which lens focal length was used. I am aware of the influence of crop factors induced by film format, sensor size and post-processing but these could be corrected for by apps like pCam, together with the info provided by the technical specs infos on sites like imdb.com or theasc.com. I nevertheless continue to run into difficulties when trying to recreate shots while using a digital aps-c sensor size or a 6x7 format film stills analog camera. Any useful guidelines would surely be appreciated!. Ray Link to comment Share on other sites More sharing options...
Stuart Brereton Posted July 6, 2014 Share Posted July 6, 2014 An APS-C Sensor is close enough to Super 35mm that focal lengths and field of view are roughly the same. To convert 6x7, this chart shows the equivalent FF focal lengths http://www.bhphotovideo.com/FrameWork/charts/comp_mamiyamed_10.html which can then easily be converted to APS-C http://www.abelcine.com/fov/ Link to comment Share on other sites More sharing options...
Ray Equis Posted July 6, 2014 Author Share Posted July 6, 2014 thanks Stuart, but as i mentioned conversion factors can be solved by apps or (for 30 euros less) by free websites. maybe i should rephrase: you see a particular shot you want to reproduce, now how do you gauge if the lens used was 27 or 35, or 35 vs. 50 mm?. FWIW i concede a tele shot should be easily differentiated from a wide angle shot. regards, Ray Link to comment Share on other sites More sharing options...

Ray Equis Posted July 6, 2014 Author Share Posted July 6, 2014 thanks for the input guys, since gladwells 10000 hour adage has recently been challenged :) (http://www.businessinsider.com/new-study-destroys-malcolm-gladwells-10000-rule-2014-7), i was hoping for some kind of shortcut. the notion that some day i will be able to "see" the focal length is comforting although a bit frustrating for a newbie like me. maybe posting a few examples and asking for advice might be a more useful approach in the short term. kind regards Ray Hannover, Germany Link to comment Share on other sites More sharing options...
Brian Drysdale Posted July 6, 2014 Share Posted July 6, 2014 Seems that to get the unpredictable aspect to work, you need to have the 10,000 hour people surrounding you. Richard Branson had recording engineers and an obsessive musician, plus others in his various businesses, while Sid Vicious had an experienced publicist visual artist, performer, clothes designer pushing the project. Best way with focal lengths is to get a stills camera and experiment with it. Link to comment Share on other sites More sharing options...

'that was shot with a wide/normal/telephoto' is usually good enough to under stand what the cinematographer was doing for the shot. These days, at least for stills, a photographer can shoot with a zoom lens, and have the focal length used recorded. The exercise then would be to shoot a bunch of shots at different focal lengths of a subject or series of subjects, then review the images with a mind for the focal length. For self-home work, I find trying to figure out lighting, quality and position, to be more useful. Edited July 7, 2014 by jeclark2006 Link to comment Share on other sites More sharing options...
