[QUOTE="thegaffney, post: 229540, member: 12353"] Oh cool, read your article about flash freezing the subject, I knew flash did that, but never really put 2 and 2 together to try in for indoor pictures with a lower shutter speed. I was playing around right now on my 70-200mm, got these results The first one was at 1/10 a second, just to test it at a speed that I would obviously get camera shake It did pretty good, i turned the flash off and did the same exposure, and it was black, so the only thing lighting it up was the flash. This was ISO 400 f/11 and 1/10 second, I think the flash was like 1/16 power [ATTACH type="full" width="30%"]62162._xfImport[/ATTACH] Then I turned the shutter speed past the sync speed to 1/500 f/11 and ISO 1600 looks sharper than above and not too bad for ISO 1600 [ATTACH type="full" width="30%"]62161._xfImport[/ATTACH] Then I put it down to the sync speed at 1/250 f/11 and ISO 800, looks about the same as above just less noise [ATTACH type="full" width="30%"]62160._xfImport[/ATTACH] My question I guess, on the first one, why was it not as sharp as the other 2? If the flash at 1/16 power went off at 1/11100 sec according to the manual, and that was the only thing lighting the room, the camera shake shouldnt of mattered right? All of these were bounced off the ceiling, would that of made a difference? [/QUOTE]
