Question about Canon 5D Mark III’s Multiple Exposure, which combines shots in-camera. I realise one purpose could be a moving subject. But I was thinking about it mainly for high contrast highlight/shadow scenes, taking the 1st shot perfectly exposed for the bright parts and another exposed for dark areas and then combine (in a sort of HDR way). But then I thought that still wouldn’t work, as my perfect highlight areas from shot one would be made brighter by the addition of shot 2. Similarly, the perfect shadows would no longer be perfect when the very dark shadows of the other shot were combined (although theoretically the combined shot should still be better than an individual one with lesser bad extremes).
The other thought related to perfect focus through the landscape scene. Rather than use f8 or f11, I thought of perfectly focusing using f4 or f5.6 with the multiple exposures first for nearby in shot one, next focus on middle distance in shot 2, and then focus for further away in shot 3. But again my hope of getting the whole distance range sharply in focus once combined I presume wouldn’t work? - because although I’ve taken every distance in perfect focus in one of the shots, that perfect bit would be blurred once I combined it with a shot where somewhere else was in perfect focus. ie an area that comes out perfect in one shot (focus or exposure) is combined with the same spot where it appears blurrier or wrongly exposed in another where somewhere else was perfect.
