Gee. I didn't think of that. In the days of film, I always carried a little folding flash unit with aluminum fan blade reflectors, and taking those little Acorn flash bulbs to add small amounts of fill. We had a half million circulation at our two magazines --- Trailer Life and MotorHome.
I was a managing editor, and when I took some outdoor camping shots in daylight and used multiple lighting (optical slaves and an onboard and off camera backlight flashes) my publisher couldn't believe it. But in thinking about it, all those tricks seem so complicated with Digital.
Maybe it is my age. But I used to perform fill-flash magic without thinking. Not so easy now. Oh, and where did I put my car keys? And my wife? Haven't seen either for 8 days.
Okay, so the lesson is: 1 -- underexpose for sky 2 -- use ND filter 3) -- fill flash for foreground subjects
Do I have that right? I've never actually seen a color shift using AD-L. I just read about it somewhere.
