P3D DrT's Lectures on Stereo Photography

["Dr. George A. Themelis" <DrT-3d@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

I had a great idea!  You know how Piper started writing the "Technical 
Page" for the newsletter of the Stereo Club of Southern California 
which then became a celebrated reference in stereo photography?  

Well, I plan to do something similar with our newsletter, starting 
with Stereogram 3.1 (this is the newsletter of the Ohio Stereo 
Photographic Society).  How about this:  "DrT's Lectures on Stereo 
Photography"?

Drawing from my 50 years (I wish!) of experience in stereo, I will 
explain concepts like:   exposure, "sunny 16", lightmeters, 
bracketing, shutter speeds, camera shake, minimum handholding speed, 
lens' aperture, f-stop, depth of field, focus, hyperfocal distance, 
sharpness, film speed, depth range, stereoscopic deviation, stereo 
base, ortho, hyper, 1/30 rule, hypo, focal length, stretch, squash, 
cardboard cutout effect, PerPax principle. (This order is not 
random... I have already written most of the text!)  All these 
concepts explained in very simple and practical terms.

And, how about this:  Advice on how to use your (fully-manual) stereo 
camera to take stereo pairs in ample light, low light, close-ups, with 
flash.  How to use a slide bar, how to do the "cha-cha", how to use 
two cameras.

A good guide for beginners and... not so beginners!
