Hot off the presses!
Gigapixel 7.1.2 was just released.
Topaz says, "This release of Gigapixel increases the stability and usability of the application across the board. We have added a camera profile for the Sony ILCE-9M3, and also fixed an issue where certain DNGs would cause a crash. Lastly, we updated the EULA for Gigapixel to bring it in-line with our other apps for commercial applications.
"This update for Gigapixel also brings a number of fixes related to rendering statuses, zoom, crop, display, and memory issues. We fixed an issue with TGA files sometimes not being able to open due to a mis-match in format."
Screenshots show upscaling a previously reduced-in-size iPhone pano 4X, upscaling a low-res logo image 4X and a quick full-autopilot 4X upscale of great-grandma.
