For photo-realistic images

I imagine a lot of users will want to use this side of the Firefly plaform to create research imagery for campaign shoots. It would be good to have some variables for the 'photo' option. It would be good to give DSLR camera options (type of lens, ISO, shutterspeed etc) to help generate a more accurate representation of what is in the users mind.

It might be good to add lighting options too...
