God, Aggie switch to decaffinated. The magic is still there with knowing what the outcome might be with regards to film speed and film development. (It might make the printing of the image you have in your head easier that is all) Besides you don't need to carry a densitometer into the field. Mine sits on my desk. Mostly it is in a case. There is no mystery here. It is a tool just like that fancy light meter you got. It does not rob the soul of an image just because you took the time to learn something about the materials you chose to work with. Senitometery has been part and parcel to photography since the beginning. Light strikes the film and excites the photons. That is all.
