How does the quality of digital compare to film?
It compares very well. The quality of a great film generated photograph depends on the same principles as a great photograph generated by digital capture. The skill of the photographer in artistry, the mastery of lighting and equipment, and a reliable lab are all paramount issues regardless of the source of image capture. In the case of digital, the photographer needs a high degree of computer mastery and considerable skill in the photo software industry standard, Adobe Photoshop. When you can see beautiful photographs from film and digital sitting side by side in the same size and not be able to tell which camera system produced them, then your choice is based on preference and the skill of the photographer, not because one camera system is better than the other.
