Art Lesson: Balance and Symmetry. Balance provides careful consideration to the placement of objects according to their weight. The elements of line, form, color and texture all help determine an object's visual weight, which is the amount of space it appears to occupy. Balance also refers to how and where you place the elements (line, form, color and texture). Symmetry creates a mirror image effect, as seen with Wyland's kissing dolphins. Wyland Tip: Most dolphin species are about 6 ft in length, the males averaging 4 to 8 in longer than females. The largest is the killer whale, which can be 19-22ft long and weigh between 8000-10000lbs.
