Hi Richard.
No Redefine doesn’t Upscale Images it quite literally Redefines the image and has been designed for very low resolution, blurry, extremely cropped or heavily compressed images, and AI-Generated images plus anything else you can think of that is of low quality.
The recommended workflow for Redefine is to use or reduce your image to one megapixel 1024 x 1024px or smaller to get the most optimized result.
Then, apply either the Redefine or Recover Enhancements before Upscaling your image using one of the methods below
As I’ve already mentioned, Redefine quite literally Redefine plus add definition and texture back into all types of images.
Redefine also, has a Creativity slider with six levels of enhancement,
Creativity Level’s 1 to 2 are best suited for adding definition and texture back into images that are soft, blurry or low quality and can also, be used with Face Recovery.
With Creativity Level’s 3 to 6 Face Recovery is disabled because, at the higher level’s the image will start to be transformed by, generating and adding information into the image that wasn’t there before and the higher the number the more surreal the image will become hence, the name Creativity.
In addition, from level 2 to 6 you’ll have access to the Advanced Settings where a text prompt box will be provided for adding information about your image or otherwise basically, you can take your imagination to the next level.
Topaz Photo AI’s Super Focus on the other hand, has a similar process when Focus Boost is applied by Downscaling the image then, applying Focus Boost before Upscaling the image back to its original size again.
But, unlike Gigapixel, Photo AI, will Downscale the image apply Focus Boost and Upscale image back to its original size automatically during the Rendering process.
Hope this helps
