My involvement in photography is both work and personal. Most of my work is done with digital cameras. Most of my personal work is done with film cameras. Digital cameras have changed the way I work (I’m talking about work-work). Once I deliver a job, I have little need to archive the work images, unless they have value for me beyond my client’s needs. Anything I photograph with film is of personal value. I like the film process, the simple cameras; the ease of using film over digital for extended travel (no rechargeable batteries, uploading, laptop, chargers + cables, finding a source of AC power, the extra weight of the cameras and zoom lenses, sensor cleaning). If I were to retire today, I would have some kind of small, quality digital camera, for quick snaps, photos to illustrate design projects and for email. I agree with “peterm1” that, digital cameras are great tools for experimentation. They provide quick feedback and allow the photographer to test ideas, on the spot, that otherwise might be kept on hold until thoroughly tested.
Digital photography is an especially good tool for learning composition. If, however, you can previsualize, you don’t need the visual feedback that digital provides. For the kind of personal snapshots I take, that are free from complex artificial lighting, film is my choice. If I were doing a portrait requiring a number of flash heads, that don’t have modeling lights, I would use a digital camera. The feedback provided by the LCD and histogram, is a much better tool for me than a flash meter and Polaroid film. If given an image of value, I would rather the image be on film than a digital file. I process my b+w and send my K14 & E6 to a lab. I guess I should add, that I scan most of my film, though I still own an enlarger.
