The web site that I found my information on was http://photoinfo.com/general/navy/photographic_composition_balance.htm
This particular article (and there are so many on a lot of photographic subjects that I bookmarked it for a later time and/or future reference) said, "The way you arrange the elements of a scene within in a picture, catch the viewer's attention, please the eye, or make a clear statement are all qualities of a good composition. By developing photographic composition skills, you can produce photographs that suggest movement, life, depth, shape, and form, recreating the impact of the original scene." The web site has 7 lessons (brief but informative) and an appendix that explains how the following principles and elements used can achieve a "pleasing" composition: center of interest, subject placement, simplicity, viewpoint and camera angle, balance, shapes and lines, pattern, volume, lighting, texture, tone, contrast, framing, foreground, background, and perspective. I have read through them all, and decided to share what I learned. Simplicity was very interesting because it mentioned a lot of the other elements to consider while composing a shot but stated, "The primary object is the reason the picture is being taken in the first place; therefore, all other elements should merely support and emphasize the main object. " Another piece of good advice that I have picked up along the way is while composing the photo in the view finder to look beyond the subject(s) to make sure nothing is growing from them off in the background. For example, Grandma is sitting by the beautiful apple tree peeling apples, but in the background there are two limbs that look as if Grandma has grown antlers. It may not be obvious at the time because the focus was on how wonderful Grandma looked sitting by the apple tree full of apples.
