I've heard many extol the virtues of off camera flash, but this mostly pertains to studio work. Does this also apply to just holding the flash away from your body as well? I have started taking portraits at events, but only with a flash mounted on my hotshoe. Will a small, bare, manual flash held away from me at arms length get me better results? The sunpak flash I'm thinking of getting weighs just under 4 ounces and is tiny. Despite this it allows for manual power output up to 1/16. What does everyone think?
