<p>Thanks both of you. That photo rogue kit looks useful, but I guess I would like to get a bit more into the detail and look at examples where the technique works well and I can reverse engineer how the effect I'm looking for was achieved if anyone has any links to share. Should I use gels for instance, is a small flash like the canon 580EX with modifiers capable of producing light that looks close enough to natural sunlight? Should I bounce it off an umbrella or try a small soft box. I can see how a Grid spot could work in some situations if I get one that had wider coverage. Bear in mind also that I will only have one, maybe two small flashes with me. As I'm going with film, I am going to do some experiments with a digital camera and flash before I go travelling so I can establish a few basic parameters. Thanks again.</p>
