17 - Tactile Texture

Tactile texture is texture that can actually be felt. In a painting, the artist can use a technique called impasto where the artist uses thick paint so a rough, 3D surface appears. Collages can also be used to create a tactile feel.

This image has tactile texture because you can clearly see the build up of bark. The rased bark is rough and riged adding to the tactile nature. However, because this is just an image of the actual image, this image itself is not tactile. Therefore, if you touched it it would be just a smooth surface.
