Most here are seasoned photographers and know the little tricks and tips for flash photography. But just in case someone might be helped with a tip, I did a C/P from another topic thread for more widespread reading. The tip applies to all the new flash units and not just the 800. Let me know if this was new to you. The 800 should have a white card with writing (guide info) on the back (white surface in front) that is recessed at the back edge of the flash top. If you have not found/used it before, pull it up when using flash tilted. That will throw light out as well as up. Card can be used part way up or all the way out and it helps to control amount of light that you want to throw out. Very useful when ceilings are too high or too dark to bounce the flash (use with a proper ceiling too). Also can be used for close outdoor fill flash but in all cases, it does require practice. I bounce the flash off the card in probably 90% of my indoor shoots. On rare occasions I will drape a tissue or open napkin over the flash when bouncing to knock the flash down when bouncing. Close ups of food dishes would be an example for good technique. Gives better even tones without hotspots.
