Differences between film and digital. The top photo was shot with 35 mm film and flash. The bottom photo was taken with a 16 MP DSLR cropped sensor using flash. You notice the film photo has a more raw and engaging feel, while the digital photo looks cleaner due to noise reduction and image processing. By default there are certain subtleties present in film that are not found in digital. (Photo Credit: Vicente Tabora Photography)
