Last summer, I did a portrait outside under some tree's. The light from the tree's filtered down. I did my best to avoid having those light spots hit hte subject, especially on the face, but there wasnt much I could do with that. The resulting picture did get some hot spots that was outside of the raw's file to fix. So im asking how do you help prevent this. One idea is to get a large object to block that light, but to get something large enough could be difficult, and really hard to use when its just myself. Another idea is to incrase the flash power, but this could result in a dark background since a flash light looses strength every time the distance is doubled, plus could result in some shadows from the people. I was just wondering if there was a secret photographer trick or device to get around this. Or wait for a cloudy patch or try a different location if its completly cloudless?
