SUNNY 16: When you're not sure about your exposure, use 
the "sunny 16" rule.  First of all, it has to be sunny, 
that's why we call it "sunny" 16.  Set your aperature to 
f16 and your shutter-speed to 1/(your film's ASA).  Most of 
the time your camera will not have a number that's an exact 
match; that's ok, just set it for the CLOSEST number.  For 
example: if your film's ASA is 400, set your camera to f16 
and 1/500 of a second.  If your ASA is 100, set the camera 
to f16 and 1/125 of a second.


  HANDHELD EXPOSURES:  If you get blurry pictures that are 
not due to focusing, your problem is probably that you are 
using a shutter-speed that is inappropriate for a hand-held 
shot.  If your shutter-speed is too long, you will actually 
record camera movement caused by small involuntary shakes 
in your hands.  The longer the focal length of your lens, 
the more this effect is noticed.  As a general rule when 
hand-holding the camera: Use a shutter speed that is at 
least 1/(the focal length of your lens) or FASTER.  For 
example: If the focal length of your lens is 50mm, you 
would want shutter speeds FASTER than 1/50 of a second.  
Therefore the slowest shutterspeed you should use is 1/60 
of a second (the bigger the lower numer, the faster 
(shorter) the exposure).  If you were using a 200mm lens, 
you should use 1/250, 1/500, 1/1000, or faster if your 
camera is capable.
