This is my first lit exterior photo. I was using one BRAUN flash that has one power level. I then layered the best ones in Gimp and set them to lighten only. Voila.
This was a physically hard shoot because I only had my wireless trigger and the camera timer set to 10 secs. So I was running to the spot I wanted to light from after hitting the shutter to start the timer. I have gotten a remote release since then! phew... I did about 35-40. I lost a lot because of small camera movements on my cheap tripod when I would set the timer off again.
The agent really liked it. It was their first sale ever and he wanted to document it!
On a side note I also did a small couple portrait of the buyers that evening.
