P3D Sunny 16 chart repost

[Paul Talbot <ptww@xxxxxxxxx>]

Sunny 16 pops up on the list from time to time due to its
usefulness with the manual stereo cameras of the '50s.  For
those who may have missed it in the past, here is a chart
that DrT has adapted from "Harris Photoguide" for Existing
Light, copyright 1989.

I have printed this chart and carry it in my camera bag.  It
is handy to have, especially for those of us who find they
can't memorize very well anymore!
