Photographers might be interested in this, especially if you have some low res images you want to use in a print project. I was going through some of my older railfan images for use in a writing project. I found some low resolution images I took around 2001 that I would like to use. The base image was about 3.1 mega-pixels (2160 by 1440 pixels) at ISO 100 and 1/180sec. The image was not noisy, but it was low-res and a bit soft.I put the image in Topaz Photo AI and let the software recommend improvements. It can remove noise, sharpen, and upscale. In this case it only recommended a 2x upscale. But in the process, it made the image sharper. So it doubled the resolution in both axes for an image size of 11.9 mega-pixels (4234 by 2822 pixels) and gave a sharper image. That is some black magic.
Here is a comparison of both images in Photoshop. The upper image is the original image enlarged to 200%. The bottom image is the same image after Topaz AI upscaling. Check it out.
