What is the additional area of control on a aperture, shutter and ISO of a camera?

Answer 1

The focal length of the lens has an impact on spatial relationships. When shooting a portrait for example, a normal or wide angle lens setting will distort facial features, especially the nose. A slight telephoto setting will provide a flatter image, and in the case of portraiture, more realistic proportions.

Answer 2

The use of a camera on full manual is for a photographer who understands the interrelationships of these controls. A photographer can use aperture and shutter to define the area of focus called Depth of Field. This is very critical in my area of photography. The three things you look at in a photograph is the most in-focus part of the image, the lightest area of the image and (if there is a person in the photo....portrait) the eyes. With Depth of Field I can make you look at the area I believe has the most importance in the photo. Aperture, shutter and ISO are critical in determining this area. This understanding of photography can make your "vision" have a more predictable result. Auto settings or alright for most weekend photographers. As a professional you would be expected to know how to control these setting and put them to their best use.

Answer 3

The only additional area of control is the manual overide of a human being. Knowing when to lose a half or third of a stop to saturate colour, knowing where to point the camera to achieve effects, (contre jour etc.), knowing how to follow, or "pan", and why. It is worth taking a basic course in photography just to get a few of these tips.

Answer 4

they are: aperture, shutter and focal length of the lens you use; however you also can change the DOF with the distance lens-object, the closer you are, the less DOF.
