If you own a Single-lens reflex camera, whether it’s a camera with film (SLR) or a digital one (DSLR), it’s a pity not to use the different possibilities.
Of course, I set my camera on full-automatic too at times, but the only advantage then is the speed of taking a picture.
If you want to have special effects like depth-of-field for example, you have to put the camera on half-automatic or manual.
The manual use of your photo camera will improve your creativity and expose a whole new area of possibilities.
