The following is a photo mosaic image created using a movie brush in the paint synthesizer. In a previous post here we described how to build a black and white pantograph effect. This post will discuss how to fill the white interior cells of a black and white pantograph image with photo mosaic blocks. This effect creates a nice organic tiling effect, where the tiles ebb and flow with the source features of the image as opposed to being laid out in a regular grid.
The effect shown below requires a 2-dimensional black and white grid to be defined by the pantograph effect. There are several of these available in the Pantograph Etching PASeq preset category. All of these PASeq presets require 2 layers. I picked the SimpleLumPanto1C PASeq preset to work with, as shown below.
