Digital vs Film
Here are a couple of conclusions I have come to, in camparing film to digital. The first is that film is still capable of giving the best and most natural imge quallity at the highest resolution. This should surpise no one, and is an assumption which most serious and professional photoographers operate under. The second conclusion is, that most of the time film doesn't deliver on it's potential, and that it generally doesn't matter. This is particularly true, in the case of 35mm film photography. This should come as some surprise to many serious photographers, and certainly caught me unawares.

computer can save, and display can show more colors than on printing (subtractive vs additive).
