    Uses Upscayl to sharpen low resolution press photos and old camera shots for How-To Geek

    Running locally on an M1 Mac Mini, Upscayl took a photo from 1024x768 to 4096x3072 in about 36 seconds. The author uses 2x for article header images and the Digital Art model for screenshots, and found 4x adds distortion.
