SteveUK said:Great writeup Clive I've had an SLR for a while (300D) and I usually shoot on manual, but I tend to guess settings more than anything (though I sometimes get a good picture).
Depth of field and controlling it is my next nemesis

ceg4048 said:All modern cameras have an automatic exposure control. They sense out how much light is streaming through the lens and they can figure out the combination of aperture and shutter speed fills the bucket exactly. The camera also allows you to pick say, an aperture and then figures out what shutter speed to use to fill the bucket exactly.
This is true only if you are shooting subjects that are far away, like landscapes. If this is the case then most of the image is in focus. If you are shooting close up and macro such as plants in the tank where DOF makes or breaks the composition then the preview button is enormously useful. :idea:saintly said:TBH the depth of fiel preview button is a waist of time IME but it's there. over time you'll just kinda know roughly what exposure settings you'll need for certain situations.

Thanks for everyones help
