I was thinking about the following: I have trouble taking sharp handheld shots with my camera + grip + a heavy lens at shutter speeds around 1/60. (Now, I know need to improve my handholding technique, but that's not where this is going). My question is: if I use a flash in a dark setting (specifically, an evening wedding reception with very dim ambient light) then can I get away with lower shutter speeds that would normally give me blurry pictures? Logically, it seems like since the flash will provide an instantaneous burst of light on my subject, then even if the shutter speed is a little slower, the blur caused by my poor handholding technique will not be captured since the burst of light is what will really be freezing motion. In this situation, I am assuming that if I take the photo without the flash using the same settings, there won't be enough ambient light to capture any details at all. However, I would like a lower shutter speed so ambient light can help contribute the tone of the evening. Anyway, this will be a situation I'll be facing in a few weeks for the first time, so your experience and input will be much appreciated!
