Here is one of the photos I took as a demonstration using just a single grid on an SB-800. I've ben using the Rogue Grid System for about a year now, I just love it. The grid comes with 2 different grid sizes, a 25 degree and a 45 degree grid, when both are positioned together you get a 16 degree grid. If your looking for a cool grid system, check them out, I carry two with me.
I position her under in front and below an airplane which was fitting for that time period. The first exposure shown here is what the camera deemed normal.
I might also add that I'll be teaching at the Santa Fe Photographic Workshops August 5-10, 2012. I'll be teaching a course titled Corporate Photography and the Annual Report.
