The resolution of Digital Single-Lens Reflex (DSLR) cameras is very close to 35mm Single-Lens Reflex (SLR) film cameras. The overall image quality can be spectacular because of excellent color quality and very little noise. In fact, the noise level in DSLR cameras is much lower than the grain associated with SLR film cameras.
In addition, digital image processing is not subject to the generation (quality) loss that occurs when processing a film image. Each step when processing a film image introduces the probability of some image quality loss; light dispersion during exposure and inaccurate color interpretation by film dye are just a couple of possible causes of image-quality reduction. Alternatively, a digital image does not have to go through these processes.
