Here's a direct side-by-side comparison of the trapped leopard images, upscaled using Topaz Sharpen+Gigapixel vs a 3x bicubic interpolation in PhotoLab:Ĭomparing the AI and conventional approaches to upscaling (please view original size) Please view full-size, but be warned, this is a very large, 36mp image. Sharpened in Sharpen AI, 3x upsized in Gigapixel AI. In other words, almost 90% of the data in this 36mp image is synthetic, but would anyone guess? Could a 1200mm FF prime lens have produced a sharper image?
I then used Gigapixel to upsize by a factor of 2x, and all looked fine, so I tried a 3x upscale. I decided that camera movement was the main problem (I can't remember if the vehicle's engine was running), so I settled on that method. 100% crop of a less than super-sharp imageīefore upsizing it, I put it through Sharpen AI, trying out each of the sharpening methods. JPEG verson of the TIFF exported from PhotoLab 2. If you look closely, it's not very sharp:
Here's an old image of mine, taken on a safari. I find it's worth checking and if necessary sharpening images in Sharpen first, before feeding them to Gigapixel. For example, Sharpen has a 'Stabilize' option which corrects for slight camera motion, something Gigapixel can't do. They definitely can and should be used together. Does this accomplish what any of the Sharpen modes, sharpen-stabilize-focus, achieve? I am trying to understand if there is a functional equivalent between Gigapixel remove blur function and either of these Sharpen functions. I want to learn how these products can be best used together. I have started testing Sharpen AI and am impressed with it. I am pleased that Topaz has continued to update and refine the software since I first purchased it. I have been impressed with Gigapixel AI since I purchased it last November.
