  1. newbie question perhaps. just watching The company you keep, frame right side around 1:54:20. whats up with the bench cutoff?.
  2. just watching nebraska again. i wonder if this shot is solely focus racking or a change in aperture as well - 0:51-0:54 - do you calculate this in advance or is it just trial and error?. whats up with the image compressing laterally when the focus changes back to the front seats?.
  3. Mark, so CoC being related to enlargment and viewing distance is after all the main denominator. now forgive me this newbie question: how do you gauge the DoF experienced on cinema size while looking on a small monitor, or for that matter, on that on a 8x10?. please do not tell me its solely a matter of experience?. is the difference that pronounced you adapt the aperture for DoF for the every aspect ratio you shoot?.
  4. thanks guys, ok i understood the cropping thing. now what about the depth of field?. leaving the CoC aside, would you say it relates more to the width, heigth or diagonal of the image?.
  5. Hi guys, i would like to reproduce certain shots i see in movies with my stills camera. with the lens and aperture info i get from asc mag or imdb techspecs so far i have used the frame's diagonal measurent to calculate lens equivalent and depth of field equivalents. i recently bought a mamiya rzii with polaback and the while researching the net for ideas i came across the following discussion: https://www.flickr.com/groups/polapremium/discuss/72157632750674921/. i get an 70x70mm (as opposed to the 69.5x56mm negative) image with the polaback. do you use the width or the diagonal to calculate lens equivalents?.
  6. 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
  7. 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
  8. 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
