Using Aerial Perspective to Create Depth in a Botanical Sketchbook

Aerial perspective is commonly used by landscape artists' to create distance - but did you know that it can also be used in botanical work to solve some of the problems that plants create - especially when painting overlapping parts of the plant. Objects that sit further back in space appear lighter, less saturated, cooler, and less detailed because of light scattering. In nature this is caused as light passes through the particulate atmosphere which contains many dust and moisture, the short wavelength of blue light means that it is scattered more than the other colours - think about how blue the the distant mountains in a landscape appear. In botanical art, we can use this same approach to create the 'illusion' of distance and to create clarity. Although the plant in front of you doesn’t have the same atmospheric distance as mountains, your eye still benefits from a visual hierarchy. Aerial perspective gives you a controlled way to create that hierarchy, This is especially helpful with layered leaves, overlapping stems and petals in a flower, which can merge together without any tonal separation. This is how it works: Paler dilute colour - pushes forms backwards Lower saturation - reduces visual weight so that he foreground is more focused Cooler hues - indicates distance Reduced detail - prevents background areas from competing with focal points To use aerial perspective - Identify the “planes” so, consider what's at the front front, middle and back Work out the colour shift — lighter and slightly cooler for each step further back Soften contrast — soft edges will recede and sharp edges advance Simplify texture — fewer veins, less granulation, gentler shadows
