Its OK talking about filters and RAW files..but some of us have only got "basic" point and shoot digitals. I used to have a filter mount for non SLRs but buggered if i can remember where it is now...
I am happy with my 3 meg Fuji..and happy with the shots I get with it..not very often I print anything large so high quality don't come into the equation. Going back to the start of this thread, you don't need a super sonic 20 meg camera to get positioning right..you just need a good eye. However I do find...and this is where digital preview comes in handy...that altering the angle of the shot just slightly can make all the difference to colour tones.
Going back to B&W..if I turn a colour shot B&W in Photoshop...what colour "filter" should I apply beforehand to darken the sky?
