Re: High Key Imaging
Bobby,
There is a law called the law of reflection. This law states that the angle of incidence is equal to the angle of reflectance. What this means to the photographer is that if you place a light off at a 45 degree angle on one side of a background (and level) it will strike the background and reflect back at a 90 degree angle (45+45=90. This will be on the opposite side of course. With two lights (one on each side) you will have twice the amount of light each bouncing off and being reflected at the same angle back. If that happens to be directly bounced into the lens you will get flare.
In my set up the lights fire straight up into my box and is then bounced straight down. I simply cannot get lens flare. BUT if my lights were at 45 degrees to the background there is a good possibility that my lens could get flare. So, I would place the lights so they are not level with the background, but are up high and then angled down. That way any bounced light will be reflected down and out rather than straight out and possibly into your lens.
