Yeah Yeah it still snowing here from time to time (like yesterday AM). And El Mirage Dry Lake is one of the places I like most. My good friend Kwan Kim has a house about 10 minuets from Dry Lake. I did my daughters senior portraits there and Lake Arrowhead(we are in northern New England no other kid in her high school had portraits like hers). We used a wood straping for a frame
(3/4" x 2 1/2" x 8"), white nylon for the diffuser (we had made this as sleeping bags to use when we were camped in the desert & and shipped them ahead of time). The only problem that we had was that the wind wanted to carry away the poor little korean boys that were holding the scrim in place. The scrim being 8' tall made a very delicate transition out of the shadow, so there was not a very hard line where the scrim stopped and sun hit the ground in back of the shadow. The sunset is dynamic there as well, watch the Faith Hill music videos the name of it eludes me now. Good luck and bring heavy guys to hold the scrim in place.
I have no online photos of my daughter except her bridal portrait.
