Above we have both a greyscale image and a height map from the hand of a Sulawesi lined gliding lizard (Draco splinotus). For two or one-dimensional measurements, greyscale images can be valuable because of their high contrast. Gel-based profilometry produces grayscale images at a range of sizes, comparable to low to medium magnification scanning electron microscopy.
