SLR 35mm are a type of camera that have a built in reflected light meter
(This meter gives an indicated exposure that assumes everything is middle
gray.
meter cant distinguish
between a light &
dark subject
will give medium gray
You must make an adjusted reading
tone image
if subjects are too dark/light
photographic Gray card 1 white Balance card can help with this issue
Averaging system can help too: take a meter reading in the dankest area &
another in the lightest then average the 2 readings
Modified zone system (exposing negative film): meter for the darkest shadow
area you want detail in stop
down twice
Relationship between: f-stop, shutter speed, $film speed
I Key to understanding film exposure
shutter speed dial: usually on top of the camera
The higher the fractional number, the sharter the exposure/length of time
similar to opertures only half Idouble the amount of light of adjacent setting
is allowed
