I've got a completely manual camera, flash ( Sunpak 422 D), and a flash meter. I am shooting outdoors at high noon in strong light which means areas of highlights as well as shaded. My subject is in partial shade (letsay under a tree) and I want to set my flash to properly fill in the person's face without loosing exposure in the lighted background. I also want to avoid making it obvious that a flash was used (I'm not a big fan of flash). The flash has the ability to adjust from FULL to 1/16th power. Indoors relying on flash, I have no problems. Outdoors using no flash (which is what I usually shoot), I have no problems. Using a manual fill flash, I can't seem to get consistent results.. either over or under exposing the subject. Normally I'd use a reflector of some sort but this is not a photoshoot and thus I don't have a reflector nor an assistant. Just a candid shot. How would you go about setting up for a fill flash properly?
