These brushes were made years ago using black and grey watercolor, India ink, and salt to achieve some unique textures and designs. The author uses these brushes more than the basic Photoshop ones when painting. They were created in Photoshop CS2 and should be compatible from CS2 onward. This set of 28 ink and watercolor brushes is perfect for expressive digital painting, textured backgrounds, artistic overlays, and adding authentic hand-crafted character to your work.
