Field notes
Postlume builds an identity kit from five to ten photos, a logo, and a colour palette, then applies that kit to three distinct thumbnail compositions: face-led, object-led, or text-led. The headline remains an editable layer and the logo is composited separately rather than rendered by the image model. Results can be judged in light and dark mock YouTube feeds, with the listed thumbnail target set at 1280×720 and under 2 MB.
