Hey Ralph,


I ussually point the flast straight up (if inside) with a +2 FEC, or straight at the subject for fill flash with a -2 FEC in lower lights and maybe -1 if outside in brighter lights. The 580 has nice manual controls but i preffer to keep in on the auto ttl and control it in the menu with flash exposure compensation.


I would recommend never using a flash on the camera pointing straight forward as your primary light source. This will lead to bad shadows and poor lighting ratios between the background and the subject.
