Thomas demonstrates the whole pipeline on a yardang starry-sky photo: one-click AI Denoise in Lightroom / Camera Raw, local texture enhancement with an inverted mask, and multi-step downscale output sharpening via the TK Actions panel — the 2023 workflow takes just three steps, far simpler than the old \"three-pass sharpening\".
