I've been asked to do a lawfirm corporate shots. They had it done before in a studio and they absolutely hated it (not by me). They want to do it in the plaza/atrium in their building (pretty much almost like a glass house). My question is, shall I stick with no flash? I wanted to do at least a fill flash but one of the partners wear glasses. What do you do when someone wears glasses? Dont use on camera external flash? This is the same spot as this photo shoot. I used no flash on this shot.
