I couldnt even imagine spending time shooting film anymore. I think it would be a step backwards, putting me at a disadvantage. The ability to preview images with a DSLR has become invaluable to me, allowing adjustments in composition and exposure instantly.
Please dont get me wrong about the process of film and developing, its a beautiful thing but its old. I cherish the memories of time spent in the darkroom but I feel that this time, in this day and age, would be better spent learning photoshop (the new darkroom).
If you want to read something good, there are three books "The Camera", "The Negative" and "The Print" by Ansel Adams that are definately worth reading.
