I agree with all the 'plus' points you make for digital, and I am not knocking it.
I just have a personal desire to improve my skills before I convert to the dark side.
But then again, playing with diigtal to learn the skills is going to be less costly and I can see when I am making mistakes earlier, rather than waiting to get the film back.
I beleive effective use of phot shop is the new skill to photography, and something no doubt I will end up converting to also.
I think the main problem with motorsport photography is that you cannot always get that close, that is probably my biggest disapointment with my photos.
But hey I'm not moaning, I enjoy what I do.
And I love looking at some of the great results that other people get.
