often push the contrast ratio beyond the 30:1 limit.
This extreme contrast
would cause background overexposure.
If you cannot avoid the bright
background, you may have to shoot the scene anyway. If this is the case, be
sure your subject is exposed properly, by using the manual iris control on the
camera, and allow the background to overexpose.
c. The dense shadows (fast falloff) on bright days can be lessened (slow
down the rate of falloff) somewhat by using a reflector. The reflector bounces
back some of the sunlight and renders the dense shadows more translucent (fig

5. When shooting in inadequate outdoor illumination, try to keep the camera as
steady as possible in order to minimize lag and comet-tailing.
It is also
important to note that when you are shooting under low light conditions, the
camera iris must be opened much wider than when shooting under adequate
critical than when shooting in bright sunlight. This is because the amount the
iris is open directly affects depth of field. When the iris on the camera is
set to a wide opening, the depth of field is shallow, meaning that some parts
of the scene will be in focus while others will not.
In good lighting
conditions, the iris will be set to a smaller opening, which increases the
depth of field.
If this knowledge is combined with the fact that the focal
length of the camera lens also affects depth of field, (the longer the lens
focal length the more shallow the depth of field will be); you should be able
to shoot under low light conditions and still keep the important parts of the
scene in acceptable focus.

However, you will recall that most lighting instruments
illuminate a color temperature of 3200 degrees kelvin.
