I'm shooting a firework display tonight, and i've been doing some reading about it. I want to make sure what i read is correct, and I need some help as well. I should have low ISO right?? 200 is the lowest my camera will go (nikon d40) Landscape is the nicest way to shoot i believe? (manual focus obviously) now arpeture and shutter speed are my questions... arpture i believe should be somewhere betweek 8 and 16... arpeture is the first number on the display right for instance right now my camera says 10 F8 I understand that 10 is the arpeture.. what is the 8 and where should it be for fireworks> shutter speed... i'm not sure i know how to change this on my camera? any help would be appreciated. also what about white balance?? should that just be on auto???
