Here's a couple of pages that I used in class last week, coming back to revisit perspective...
Showing two simple methods of finding a correct square, in a one point set up and a two point setup.
Nothing new here - this is all in Loomis and others, but I find that sometimes the knowledge has to be winkled out and the step by step isn't always completely clear... ah well, that which is worth having, is worth working for, isn't it?
These are done FREE hand ...well, a little help with the shift key after i took to Photoshop, but don't use a ruler with the initial sketch!
Please vet these for me - are the instructions clear? Easy to follow? I'd like to use these in the BOOK when I get it OUT!
