PJ Palomaki Posted August 8, 2015 Share Posted August 8, 2015 Hi, I recently had an opportunity to shoot on film for the first time in my life (crazy, I know) and a question came up which left me thinking.. Apologies as it's probably a very noob question: When I shoot slow/fast motion on digital, I change the shutter speed to maintain the same motion blur as for the 'normal' speed, i.e. shooting on 25p, 1/50 'normally' and then do 50p for instance, I shoot at 1/100 to have the same amount motion blur. Assuming you want the same motion blur, how would you do this shooting on film? I am right in understanding that 180 degree shutter angle will remain 180 regardless of what frame rate you shoot? I.e. shooting 25fps and 50fps means that the shutter turns twice as fast to maintain 180 degree shutter angle? I hadn't noticed but was told that Red has an option for shutter to have either a shutter speed (1/xxxx) or angle (degrees), does this mean if you want to shoot everything at 180 degrees, you don't have to keep changing the angle for different fps? But surely, even if you can capture everything at 180 degrees, in playback, there will be variations of motion blur as the angle was relative to the fps? I.e. 25fps has 180 degrees and 50p has 180 degrees, but compared to each other, they don't match? I would've automatically calculated the difference between the degrees when under/overcranking and changed the shutter accordingly, but I was told by two working AC's that this is incorrect... If anyone can shed any light or knows of any resource on this, I'd really appreciate it! Thanks, PJ Quote Link to comment Share on other sites More sharing options...
