[QUOTE="WayneF, post: 227391, member: 12496"] In dim light (where you need flash), camera A or P modes will switch to a 1/60 second Minimum Shutter Speed With Flash. That is not a correct exposure for anything, its just that if you are using flash, it doesn't think you need some slower shutter speed for a dim ambient. But there are a couple of exceptions. If your flash sync mode is Slow Sync or Rear Curtain Sync (D5100 manual page 51), it will retain whatever slow shutter speed that it meters for the dim ambient. Sounds like you must have that selected, but you want the default Minimum Shutter Speed With Flash, which is 1/60 second (some top end models have a menu to adjust that Minimum). So just set Flash Sync mode to be normal mode (called Fill Flash in D5100), which is just regular front curtain sync. (instead of Slow or Rear Curtain sync). And avoid the Red Eye Reduction, it causes extra flashing and a one second delay you don't want. That should get you a shutter speed of 1/60 second (with flash in dim ambient), in camera A mode. Or... considered better by some - You can simply use camera M mode (manual) and set any shutter speed you want. In M mode, you still set aperture just like in camera A mode, and the flash works into that. A TTL flash is still fully automatic flash exposure in ANY camera mode. Manual just adds setting shutter speed. The flash is not affected by shutter speed, which is only for ambient continuous light. You can set it up to the Maximum Shutter Sync Speed, which is 1/200 second. Shutter Priority mode S sets any shutter speed, but in dim ambient, it of course ensures the lens is wide open. You may much prefer it to be stopped down at least one stop. Since the flash is not even affected by shutter speed, the other modes are better than S mode. [/QUOTE]
