Digital Photography Principles

This is an informational page and it contains a variety of interesting photography-related articles.

The first article focuses on optical and electronical principles of modern digital single-lens reflex (DSLR) cameras. The second article describes the technology used in camera lenses and related mechanics.

The third article describes how technical know-how can be combined with general rules of photography. My experience has shown that understanding technical principles of DSLRs really make a huge difference on how your photos turn out. The article also offers tips and tutorials on how to achieve professional results.
