Introduction to three-dimensional photography 
									 
Personal history 
At tender age of 13, I was given my first camera by an old man living 
on other end of village. It was this 8 x10 inch glass plate camera 
which started my journey. I never had my plates or films developed 
by lab, did all by myself and ruined much of it. But I learned 
	When graduating to colour, it was Agfacolor. If I remember 
correctly, the main ingredient in their developer was di-ethyl 
paraphenylendiaminsulphate. Later in Canada, in an art studio of 
my own I blossomed into three-dimensional branch. I was 
proficient and had experiences, so I was able to teach 3-D course at 
the renown Sheridan College. However, despite my expertise and 
fully equipped photo studio I was not interested in starting a 
business. The cost of material was prohibitive and I did not have the 
conscience to charge the customers more. Besides, I had well paid 
and steady job. This applies equally to all other art. When moving to 
Philippines I lost most of my equipment to evil people, some gave 
away virtually free. My knowledge nobody can take away from me. 
 
Lesson 1 - Three-dimensional vision. 
Humans have two front-facing eyes with distance between some 2 
and half inches. This is the basis of our perception of space. Second 
important input for our brain to work with is ability of our eyes to 
accommodate, change curvature in eye’s lens in order to focus on 
near and distant objects.  Changing curvature of lens accomplished 
by different tension in the lens muscles is simultaneous with 
convergence, which is ability to move, change direction the eye axes 
point from acute angle employed in looking at close objects to 
parallel when focussing onto horizon. 
	In taking and viewing three-dimensional, also called “stereo” 
images only the first two requirements, distance between camera lenses 
and between our ayes and eye convergence are functional. 
Next, lesson 2 - how the pictures are taken. No big deal.
