Develop focal points
The first thing people notice in a picture are human faces, so they become natural focal points and should, as such, be placed carefully. There are several ways to accentuate them or shift the interest towards other areas of the image. One is manipulating light, such as keeping most of the image relatively equally lit and have strong light hit the area we want to stand out. Variation in brush strokes or colours can also be used, rendering the focal point and keeping the rest of the image rougher and more desaturated.
