This started with a photo of a model in a red flowing dress. I added a fractal background made in FraxHD, created the “melting look” with Form>Sort feature in iColorama, then finished with metal textures from iColorama layered and masked on top.
Sort is one my favorite effects to play with and several apps have some form of “sort” as a texturing or distortion style that you can apply to the right photo.
