SLR - single shot reflex.

Apperture- one way of controlling the intake of light by widening and shortening the lense. widening the lense is used in dark areas or night to help gather as much light intake and shortening the lense is or lighter or day pictures for less light intake. sizes between 2.4-22

Shutter speed- the slower the shuter the shutter speed exposes mored light to the film and the faster exposes less. speeds between 4 seconds and 1/4000 of a second.

if using hand held you have to set the speed as 1/25 of a second as minimum as the natural shake of the hand causes bluring on anything slower.

DOF depth of field the ower the F no. the smaller the DOF and vice versa.
