I'm not that new to photography, but new to studio lighting. I have a client that has a beautiful Victorian gown that she would like photos of with her wearing it. The location is Banff Springs Hotel. I only have one strobe (AB800) and a shoot thru umbrella. My question is, considering she wants a full body photograph, should i use window light and the strobe for fill or just use the strobe? If I just use the strobe im worried about fall-off. Also what kind of set up should I use? I would love some feed back on my dilemma. Thanks.
