About Topaz Bloom 2
Topaz Bloom 2 is a generative image upscaler that invents new, believable detail as it enlarges, with particular attention to skin and facial detail. Steer the added detail with a prompt and adjust how much is invented.
Use it to creatively enhance and upscale portraits and other images where realistic skin, hair, and texture matter.
