so I am doing a trash the dress later this week. We will be downtown (alleyways, streets buildings etc), but the only time she can do this is on a weekend or at night...since I have weddings most weekends the night it is. Any one have any examples of lighting this. I have done many engagement sessions in the dark in the city but want a different look....more sexy and fashion like but want to have some great lighting....I usually have an off camera light and can bring an umbrella if need be. I also have a video light that I received recently and am getting used to that. I have a few of these coming up but this is the only one that is at night. The groom will be there as well....

Thanks!
