And what better you can say about a graphic software? As an Hypercard user I remembered this dithering vs. the PC squared-pattern, but always think Photoshop's was the same. Wrong. Pattern in PS has a smaller grain, but tends to "blur" and loss details. HyperDither gives a more contrasty but richer in midtones image. It's a beautiful tool for image workers. Thank you! (An idea coming off my mind is to convert this to a PS plugin, but this little thing is so quick that I don't know if it is really a good idea...)
