Lots of good advice/info in this thread.
Here is one item I consider well worth every penny of the $49 it costs, which I alluded to earlier.
Darrell,
You put this on an SB800 or any good digital flash and you will shoot like a Pro.
Not one indoor shot needing flash should ever be without this device.
Lots of other variations in the market but I truly like this one.
What most photographers accomplish with multiple lighting and 2 to 1 ratio for portraits, this can accomplish almost the same look, without the multiple lights.
Knocks out any harsh glare on subjects, eliminates shadows cast by the flash, eliminates red eye as no direct light to eye to bounce off iris, opens up the background to simulate what the eye sees as opposed the darkness when flash straight on, etc.
