I have been trying to find out why 35mm film (and presumably full-frame digital sensors) are actually not 35mm at all, but 24 x 36mm.
I am ready to be corrected but as far as I gather, original 35mm film stock was (is) 35mm from side to side in cine cameras (top to bottom in SLR's) but taking away the sprocket holes, the effective film width (height) is 24mm. Is it that the exposed bit is 35mm long with an extra bit to separate the frames making it 36mm?
Is this correct or am I talking b*****ks? I really should know, I've been using film since 1973.
