I've deleted the images, but I was there trying all the different speeds in S mode because the images were practically black (with Auto ISO off and adjusting values to see if it would make a difference). I kept getting the 'subject too dark' message at 1/125sec. I was shooting towards the window as the speaker had the window behind him and to the side. At 1/125 I switched on Auto ISO and the EXIF data showed the ISO was 3200 and the image was still very dark and very noisy. So I switched to A mode (played with different aperture numbers) and the camera selected around 1/20 sec and ISO 3200. The images in A mode are well exposed enough but blurry (and the moving hand is all blur, no shape). I was in a well lit room, the speaker was standing near the window so we had sunlight and overhead ceiling lights. Then I tried auto-no-flash and the EXIF data showed f/5.6, ISO 3200, 1/30 and there is some blur. It seems ISO was going right up to 3200 when I had Auto ISO on. When I was manually changing the ISO and shutter speed, again everything was dark and the 'subject too dark' was happening around 1/125sec. I understand why the camera says 'subject too dark, cannot adjust exposure' (in the technical sense)... but I didn't think I'd be getting that (and black photos) at 1/125 shooting in a well lit room. Does it seem okay that Auto ISO was going up to 3200? I will re-read everything and try again. I scribbled down notes based on the advice given in this thread but no luck. I worked in IT for twenty years and I'm quite confident the problem here is the user and not the hardware, so I don't want to say there's something wrong with the camera. The user, on the other hand... * Sorry, still can't get this to display as separate paragraphs. I tried the shift+enter tip but no change.
