I think you could not see the definition about the "real photography" and the reason why I call it "real" and yes with a 35mm camera you can not catch the right moment and you can not change iso you even don't know what the picture which was taken just before looks like...However i disagree with your "always rewarding" word...if you wash well you get well results or as you say rewarding but not always...as long as you are careful and wash the film well.

Have a nice night my friend...
