You can choose between four different sizes (1x, 2x, 4x or Max). This being said it’s a very useful tool to 1) recover older pictures from lower-resolution cameras, 2) to allow for larger print sizes, 3) to allow for extreme cropping even with high-res shots from modern cameras (particularly useful for wildlife shots) and 4) to increase the size of AI-generated images (which have as of now a very low resolution). Most likely you’ll only increase the artifacts. If you have an image shot with a smartphone don’t expect miracles. Keep in mind that this tool works well with files that have a lot of information and are not too compressed, like those generated with a mirrorless or DSLR camera. Most likely you will use it with the Enhance Resolution Tool. Upscale is the last section and is not applied automatically. Just like the Sharpen tool, it can actually fix an image or completely ruin it, especially if the face is rather small and doesn’t have many details. If the AI doesn’t detect any face, the Recover Faces tool is locked. The Recover Faces tool is similar to the Sharpen tool but it focuses on faces and it works very well only if the faces are slightly out of focus.The motion blur setting can often help recover unusable pictures. There are three settings: Lens Blur, Motion Blur, and Standard mode. The AI automatically detects the subject, creates a mask, and then improves the image. Sometimes it enhances greatly the image, some other times it simply ruins it. The Sharpen tool is a kind of hit-or-miss thing.The only downside is that if you apply a very aggressive noise reduction, the image can have a “plasticky” feeling. I think this is where Topaz really shines. In the Image Quality section, you can find 5 tools: Remove Noise, Sharpen, Recover Faces, and Enhance Resolution.
