26 High-Res Watercolour Splatter Brushes for Photoshop CS3. A variety of splatters with round, directional, globs, fine mist and dots. High-Res source files provided in tonal greyscale PNG format with transparency (RGBA) for maximum flexibility. If you have a newer or older version of Photoshop you can easily recreate the brush set from the included source files. These brushes have been painstakingly crafted to avoid hard ‘square’ edges and to preserve fine details.
