How do you get from photo to canvas?

[Allan Rahbek]

I have made my Proportional Dividers from two flat beech sticks ( for stirring paint ) .1" wide x 3/16" thick x 12" long. Total length, including the iron nails, is 13".

7 different positions for the axis, to measure from 1" : 1 3/16" to 1" : 3 1/2"
Hole NR. 4 measures 1" : 2" and it will reach 15" with the long legs.

Hi Mike and Allan,

I thought I'd add my 2 cents worth. Here are a pair of dividers I made specifically to copy from fired clay scale to wet clay scale, about 12.5%. They will take inside and outside measurements. The wood is basswood model making stock from an art supply store. Length: 23 inches. Maximum measurement: 23.5 inches.

Same principal as your divider examples, just larger and for 3-D work.

Conceivably, although I have not tried this yet, these dividers could be used for painting from a live model/sitter, either to copy in direct scale, or 112.5%, or 88.8%.
