If you were to enlarge a TIFF file that has layers, then the layers will be merged. In addition, it doesn’t support TIFF layers. If you want to enlarge a RAW file, I suggest saving the image as a TIFF file then use Gigapixel to upscale to TIFF. I tried correcting the color and contrast by playing with the color settings and spaces in Photoshop but it didn’t work. The color and contrast look washed out once completed to a TIFF or JPEG file. The software will not output a RAW file.Īlso, Gigapixel’s RAW rendering is not good. So, you can’t enlarge everything by 6 times. When enabled, this feature will enlarge small faces (16×16 to 64×64 pixels) with more detail and sharpness.Ī few important notes about Topaz Gigapixel AI: Gigapixel caps the upscale by either height or width to 22,000 and 32,000 pixels for TIFF and JPEG outputs, respectively. Topaz Gigapixel AI also has face refinement. Not only was the final image still sharp, but the noise was also reduced. Cropped JPEG image sample I used for the TIFF scenario.
Lastly, I used a 5496×3670 TIFF image (originally a DNG image) and expanded it by 400%. The enlarged photo is a whopping 183 MB which I’m not going to load on this blog post. To compare the images yourself you’ll need to see the original and expanded files. However, this image is good to set a floor quality for Gigapixel AI. I did take it with a mobile phone while on a boat (think moving platform). Keep in mind the original image quality is not great in terms of professional photography standards.
On the other hand, when you zoom in to the same area on the upscaled photo, it looks painterly. Before image.Īnother thing I noticed is when you zoom in on the original photo, it looks pixelated - as expected. But it is only noticeable when you really zoom in. I did notice halos along the horizon on the enlarged photo but there were already some artifacts in the original horizon. I was surprised by the quality it’s actually good. I enlarged the image by 600%, which is the largest size the software can produce. To test Gigapixel AI, I first used a 4032×2268 JPEG image that I photographed with my Samsung Galaxy S8.
