Thanks very much! If they will go for outdoor I can pick some locations..with fingers crossed for weather! I am used to using the SB800 in bounce and fill flash modes. For some reason, dof just slipped my mind totally! Shots like those shown here are so much more natural than the studio with the "grand masters" or some other background..looking so studioish. These outdoor shots show more heart in the people "as people" and not just a lineup for the studio shot. The contrast ratio is the relationship in light from essentially one side of the shot to the other. 2 stops difference...2 squared is 4. Ratio is 4:1. Maybe I should have said 1:4 Done with one light and reflectors or two lights positioned differently or at different power levels. If one side of the face reads f/11 and the other reads f/5.6(incident metering), you have 2 stops difference or the ratio of contrast shown. I can say it..have only tried using this a few times but no real experience. I would be much more comfortable with the camera and flash outdoors. We will see! Greart shots, btw. Tom.
