SLR Camera notes

The slower the shutter speed the the more light that hits the film.
The smaller the aperture the less light that hits the film.

Shutter Speed
Slow- 1 Second
1/30 second
V.Fast- 1/1000

The lower the number is the larger the aperture and the higher, the smaller.
(a low aperture will be blurred)

1/4 sec' + f/2.8 = white
1/4 sec' + f/4 = too bright
1/8 sec' + f/4 = too bright
1/8 sec' + f/5.6 = too bright/blurry
1/15 sec' + f/5.6 = too bright/blurry
1/15 sec' + f/22 = too dark

Depth of Field
-Foreground
-Backround

The smaller the aperture the greater the depth of field.
