Hi guys... I'm doing a shoot for someone tomorrow. Basically it's a quit portrait. It's in an office, but I'll go outside also. Got any tips? I'll be using a hotshoe flash, d80, 50mm 1.8 (also have 18-200vr) If I'm in the office building, any quick tips for best flash? Should I let it be on auto, or should I manually set the flash power. Deflect? Outside... fill flash tips? Anything you could give me would be great, Thanks, Bill.
