Build a Photo Mosaic From Scratch Using Lightroom and Photoshop

Build a Photo Mosaic From Scratch Using Lightroom and Photoshop

Every few months I get a message that starts with something like: “I have 200 employee headshots and I want to do something interesting with them.” I used to have no good answer for that. A slideshow felt lazy. A contact sheet felt clinical. But a photo mosaic - a single image built from dozens or hundreds of smaller photos - that actually makes people stop scrolling. This technique landed on my radar through Aaron Nace’s tutorial over at PHLEARN, and I want to walk you through what he covers because the workflow is genuinely clever.
