Whenever I'm taking pictures indoors at night, even though I could still auto focus without it doing this, the flash sends strobes out blinding my subjects and confusing them into thinking I already took the picture. I'm shooting my friends wedding tomorrow, and part of it is indoors at night. I would prefer to avoid the strobe light effect. Is there some way to disable this? The people at shutterbug had no idea. The last wedding I went to I saw professional photographers shooting indoors at night, and their camera flashes never strobed. Any help appreciated.
