To locate the center of interest with the Golden Section: Divide the height of your canvas by 2.62 and determine a horizontal line through this point.
Then divide the width of your canvas by 2.62 and draw a vertical line through this point.
The intersection of these two lines is a magical spot for your center of interest.
For example, the center of interest on an 8 1/2 x 11 inch standard sheet of typewriter paper would be determined thus:
8.5 divided by 2.62 = 3.2 inches and 11 divided by 2.62 = 4.2inches.
The intersection of the two lines described above is the exact point of the kiss in this painting above.
