This results in smaller retinal images for infants. The vision of infants under one month of age ranges from 6/240 to 6/60 (20/800 to 20/200). [4] By two months, visual acuity improves to 6/45 (20/150). By four months, acuity improves by a factor of 2 – calculated to be 6/18 (20/60) vision.

The maximum contrast of an image is termed the contrast ratio or dynamic range. In images where the contrast ratio approaches the maximum possible for the medium, there is a conservation of contrast. In such cases, increasing contrast in certain parts of the image will necessarily result in a decrease in contrast elsewhere.

Van Gogh used heavy outlines in blue around the images of mother and baby. [3] To symbolize the closeness of mother and baby, he used adjacent colors of the color wheel, green, blue and yellow in this work.
