The selected shutter speed should
line up with the small straight line
on the top middle of your lens barrel.
Now, look through the viewfinder.
On the bottom, there are small
weather symbols that correspond
to your Aperture setting. The
aperture is an iris-like opening in
the lens which regulates the light
admitted through it. Move the
Aperture Selection (17) to the
weather symbol that most
resembles your outside condition -
full sun (f/16), partial sun (f/11), light
clouds (f/8), heavy clouds (f/5.6), or
overcast (f/4). You now have the
correct exposure for a daytime shot!
