I have to take some pics of a recent project we just completed, part was low voltage landscape lighting. I plan on taking photos before sunrise, with my Canon and a tripod. What shutter speed and iso would be a good starting point to produce a picture that would compliment the lighting? Also should I use the self timer option? Equipment is a Canon T1i and lens is a Canon EF 17-40 1:4 L USM, any help would be appreciated.
