I will soon have the opportunity to visit a glass factory. Since I will likely not go there for a long time, I'd like to make sure I get the most out of my shots.
I will bring my EOS 550D with the 18-55mm/3.5-5.6 kit lens with me. Is there a particular set of options I should aim for to capture the glow of fluid glass? I'm concerned that I will rather underexpose the pictures: Glassblowers work quite hectically and my lens is not particularly fast. Will using the flash destroy the natural look of glass? Or will it yield interesting specular highlights?
Another aspect I'm concerned about is that the images will look flat since there will probably be windows letting in light, the rather dark rooms and the glowing ovens with fire in them. Is there a recipe to maximize the details in each of the wildly differently luminated areas applicable in this scenario?
