Smoke, thanks for the info on skin, I learned something. Yes, using a gold reflector adds a color cast, but for my taste, it looks great. But you are absolutely right, silver or white is more neutral. A zebra, silver/gold stripped falls in between. I actually use it on the white birds in my back yard and the color cast is minimal but I get the power of 2 metallics rather than white which isn't strong enough at the distances the egrets and wood storks maintain. I also have tried plexi mirrors on them but it tends to be to strong and hard. Outdoors, I usually bang it through a diffuser in close. In your second shot with one with dark and the other light skinned, the inverse square rule is your friend. I would put the main on the side of the darker skin and as intensity falls off, the light skin doesn't blow out. Same principle with grooms in black tux and bride in white gown. This is a powerful shot and captures the joyful and uninhibited personality. It has meaning to even a casual viewer and probably lots of meaning to the family. Great job.
