Describes each camera setting in detail and what to use it for. Scroll past all of the basic stuff and it gets into Histograms, Metering Modes, White Balance Presets, different types of autofocus, etc. Great reference!
General Rules and tips for ISO Camera Settings: •Use an ISO of 100 or 200 when taking photographs outside in sunny conditions. • If the sky is overcast or it is evening time, then use an ISO within the range of 400 to 800. • Night time or in cases of low light you might need to set your digital camera ISO to 1600. If you don't then your photo will appear too dark if at all.
