St Pauls Cathedral Birmingham
|1/200 sec f5.6 16mm ISO 200|
The repetition rate on the stained glass focuses the eye directly to follow the line up and across. There is no differentiation or interference in the rhythm as it flows through the frame up to the opening window at the top where the rhythm is interrupted.

Rhythm helps to make the viewer feel comfortable with a busy and full framed composition by ensuring consistency and instant recognition of the subject. It invokes peace and helps to attract instant attention by its sense of order. I would imagine this would be the format that advertisers would follow to market their product.
Pattern to add interest and depth with a little touch of realism by creating visual activity beyond the flat composition.
