Photographic guru's... I need your help... I have recently bought the Fuji Film HS10 bridge camera. It has all the functionality as a DSLR, shoots in RAW etc. etc. Here's the spec: FinePix HS10 / HS11 | Fujifilm Global Now, shooting the kids whilst busy pulling the dog's tail etc. is one thing, but taking photos of gorgonian polyp's is another. I am really struggling to get my head around this whole ISO, Apperture and Shutterspeed thing. I have seen the movies, read google but there are no real advise out there on how to take good aquarium photos. Taking into consideration my water is much more blue than it is white due to more actinic light, what are the basic rules then of taking nice photos of coral, and then of fish? Should I use Macro Functions, what ISO should I use, Shutter Speed etc? I know there are no real ABC answer here as there are many factors, but where do I start. What is a good average ISO, average apperture etc to use? Thank you!!!
