Notes

Composition Rule of Thirds or Golden Ratio So, the first "golden" rule is the "Rule of Thirds" or "Golden Ratio". It affects the ratio (1:1.618) of a picture size, as well as the placement of the main subjects in the photo. This ratio is close to the 35mm ratio, so you don't need to change the size of the photo in most cases. But you need to consider the composition: main subject should lie on one of the four lines or four intersections (subject's eye for example). Truthfully speaking, these rules are not always the same. Rule of Thirds is a simplified version of the Golden Mean.
	Golden Triangles Another rule is the "Golden Triangles". It's more convenient for photos with diagonal lines. There are three triangles with corresponding shapes. Just roughly place three subjects with approximate equal sizes in these triangles and this rule will be kept.
Golden Spiral or Golden Rectangle And one more rule is a "Golden Spiral" or "Golden Rectangle" (you'll see why it's a rectangle in the toolssection). There should be something, leading the eye to the center of the composition. It could be a line or several subjects. This "something" could just be there without leading the eyes, but it will fulfill its purpose anyway.
