Alright, you took the shots last night. Hope everything went well!


For future shoots, I would suggest removing any filters.Long exposures generally pick up any dust spots or smudges on the filter. Oh, and by the way, make sure you have a tripod. I have taken night
shots at 12mm at 1/30, but the results are somewhat dodgy. A good
tripod will give you flexibility to do whatever you need to do to get the shot. Set Av (Aperture Priority) and set your aperture to f/8-f/16. A narrow aperture will not only improve depth of field, but also give light sources a spectral look. ISO 100 is good like you mentioned. Try to focus with the centre point on a light source in the scene, and then recompose.
