As it happens, the sunny day rule is equivalent to using an
incident light meter, which is better for slides unless one
is Ansel Adams (or more or less as good). I would add a few
lines having to do with the time of day:

1/100   f16      0      Sunny and bright, your shadow half your height
1/100   f11     -1      Sunny and bright, your shadow same as your height
1/100   f8      -2      Sunny and bright, your shadow twice your height

This is often given according to time of day, but then the season has
to be factored in, which gets complicated.

Good luck -- George Gioumousis
