At times, placing natural elements of a composition along a diagonal makes the picture more pleasing and dynamic. However, the diagonal line doesn't have to be an actual line or straight one but should have most elements along the diagonal.
THIS TECHNIQUE of photography in which some elements of a composition are placed along a diagonal is called the ‘diagonal method’ and is treated as a rule of thumb by many hobbyists to make pictures dynamic.
By visualizing lines with an angle of 45 degrees from the corners or sides of an image, one can find out which details to emphasize in the photograph. Many photographers after practice become intuitive in creating dynamic compositions through diagonal method.
Even while taking the important details on paintings and on etchings of an art work diagonal method is helpful. For taking the picture of rivers, this technique is often used.
