Lightroom: upscale cropped photos with Topaz Gigapixel

This tutorial explains how to use Generative Upscale with Topaz Gigapixel inside Lightroom after cropping a photograph. The example starts with a 7,952 × 5,304-pixel egret photo and crops it to 2,074 × 2,592 pixels. Choosing 4x enlargement brings the longest side to 10,368 pixels.

The presenter accesses Generative Upscale through the Photo menu or the image's right-click menu, then chooses 2x or 4x. The tutorial states that processing consumes 10 or 20 generative credits depending on the final file size, with a maximum of 65,000 pixels on the longest side. It contrasts these choices with Super Resolution's 2x enlargement.

Although the source image can reside in local storage or the cloud, this workflow processes images in the cloud and requires an internet connection. It is not an offline method. The output is a new DNG with Lightroom edits permanently applied, so the presenter recommends upscaling at the end of editing. The original remains available for further changes.

The final comparison examines feather and eye detail at 100% zoom. The presenter reports good results but cautions that extreme crops of less sharp originals may fare worse. He suggests the process for printing and considers it less useful for images shared only on social media.
