The link below is a video on 'smart objects' in Photoshop – skip it to 43:00 mins and you'll find a really useful way of seeing what one of your photographs might look under different colour conditions.
Basically, you can set up a file in Photoshop that acts as a template into which you can 'drop' any photograph you have and see lots of variations of it. The number of variations is up to you – after all, you set them up. The way the photograph varies is also up to what adjustments you choose – but colour adjustments are the main options.
I followed the video to create a template for lots of different black and white filters on a photo of of mine. The differences can sometimes be very subtle, but you'll find some great results – like the second one in from the left (top row). It has a really good wide range of tones and not too harsh a contrast. Photoshop does offer predefined variations but they're very basic and you don't get much control over them so this is the way to go.
