Or maybe I don't understand the apparently erratic operation of the camera: it doesn't respond in the same way to settings depending on whether I'm testing at home or out. Regardless of whether you are using M or A modes, with a fixed aperture (e.g. your favourite f0.95 maximum aperture) and when working with DNG (RAW) images, for any selected ISO and shutter speed combination, you'll see the same histograms in both A and M modes. Varying the shutter speed and / or the ISO, can change the shape of the histogram. Optimising the histogram for any exposure situation should optimise the actual exposure. How you 'optimise' the histogram (i.e. determine/select the best shape) depends on personal preference ref control of highlights and shadows. One of the EVF's live view screen modes shows the histogram. On my SL 601 the live view histogram is shown in the top left hand corner of the EVF monitor. It's also worth checking the exposed image's histogram which can differ from the live view histogram. A very 'awkward / odd looking' histogram can be adjusted by use of graduated filters.

Yes, thank you. What you are teachning me is not that different from what I already know. But, as mostly a street photographer, I don't look the histogram before to shoot. I will take of it when shooting for landscapes...😉 Edited January 29 by Kostia 1 Link to post Share on other sites More sharing options...
