"Visual weight" - the tendency of a picture element to seem heavy - is much more subtle and complex than the physical weight of an object. It depends on such things as size, tone, shape, location in the picture area, texture and "human interest". We can put a pork chop or a Ioaded truck and trailer on a scale and objectively measure the weight in pounds and ounces. But not so a child's silhouette against the sky, a fragment of shiny water, or a broken window in a warehouse wall. These or any other visual element that might go into a picture must be judged subjectively. You must experiment with different viewpoints or trip your shutter at just the right moment when everything "feels" in balance. The Decisive Moment!

However, psychological experiments have come up with some guidance. some things to look for and consider.

1. Large size.

2. Object's tone contrasting strongly with surrounding areas of tone.

3. Bright tone.

4. Light color.

5. Irregular shape.

6. Any form of human interest: child, animal, especially the face.

7. Location close to center of picture area.

8. Location in upper part of picture area.

9. Location on right side.

10. Isolated by space.

1. Small size.

2. Object's tone blending with surrounding areas tone.

3. Dark tone.

4. Dark color.

5. Smooth, regular shape

6. Abstracts shape or form, not directly related to human beings.

7. location away from picture area. The background noise.

8. location in lower part of picture area.

9. Location on left side.

1O. Crowded close to other shapes.

Make full use of the picture area. This doesn't mean that you must fill every square inch with busy detail. Areas of "white space" (a.k.a. negative space) can give the eye a rest and make important objects stand out clearly, But avoid meaningless of vacant space - especially if they are at the edge or at the bottom of your photograph.

Decide what are the most important elements in your picture and emphasize them by compositional means - value (tone) contrast, hue (color) contrast (when shooting color), placement, leading the eye to them with lines of movement, making them larger and clear, etc. Your picture may have more than one "center of interest" - but it should be instantly clear to the viewer what the most important things are.

Don't crowd everything to the top, bottom or just one side of the picture.

Avoid an arrangement that looks too scattered. Relate important objects to each other by grouping them, overlapping, or trying them together with lines of movement.

Usually it’s best not to split your picture into two exactly equal parts. either horizontally or vertically by placing the subject exactly in the middle. A varied, dynamic use of the picture area is more interesting.
