This is a lengthy process of feeding the application thousands of images with normal and downscale resolutions. With Topaz ‘Gigapixel AI’, this also involved machine learning.

Up-scaling engines like this have evolved in the past few years. Take a gander at this letter ‘W’ that I processed so you can understand what ‘Gigapixel AI’ does at a most basic level. The software does this by filling in the blanks, so to say. In comes ‘Gigapixel AI’ to upscale that crop up to 6 times. Details looks fine at first, but when you zoom in you see that it looks blurry. You cropped the hell out of that 16 MP sensor image and now you’re left with a 1,2 MP cutout. Say you’ve gotten a fantastic image of a bird-in-flight, but your tele-zoom just wasn’t long enough. Since printing images is more or less going out of fashion, maybe a better, more modern use case would be up-scaling a cropped image. It’s always possible to export an image to a larger size in an application like Lightroom, but you’ll notice a loss in sharpness and overall quality. You can use it to enlarge full-sized images to print them larger or to upscale your low resolution images.

Topaz ‘Gigapixel AI’ is an application made for photo enlargement.
