You can read all the details in this blog post from the ACR team explaining what it is and how they developed it.
There hasn't been much in the way of advancement until last week when Adobe released an update for Photoshop and Camera Raw that included a new feature they are calling Super Resolution. The upsampling tools available to us reached a plateau over the last few years. Both do a fairly decent job of making enlargements with minimal quality loss. Genuine Fractals was later purchased by OnOne software and this excellent upsampling algorithm still lives on today as part of On1 Resize and On1 Raw.Īlien Skin (now rebranded as Exposure Software) has their own upsampling plugin called Blow Up and Topaz has one called Gigapixel AI. The results it produced were far superior to the native ones in Photoshop like Bicubic and Bilinear and it really was a game-changer at the time it was released to the public. This program used a branch of mathematics called fractal geometry to create an entirely new algorithm for enlargement that was capable of scaling images up or down with minimal loss of quality. The first great leap forward in enlarging software came with the release of a plugin called Genuine Fractals Print Pro from Alatamira Software all the way back in 1999. We need a better way to make bigger images! But they all have their limitations and the larger you try to go with an image, the more you will begin to see flaws like jagged edges and blurred details. "Preserve Details" works best for enlargements. "Nearest Neighbor" works well for hard edges. They have names like "Bicubic", "Bilinear", "Nearest Neighbor", and "Preserve Details" and each one is designed to work with different types of images and for different enlargement (or reduction) tasks.
Photoshop alone offers quite a number of different enlarging algorithms you can use when resizing an image. Software makers have created a variety of solutions over the years in an effort to solve the inherent problems of upsampling. In order to make digital photos larger, images must be "upsampled" using a software algorithm to add more pixels.īecause most digital photos are made up of a grid or "bitmap" of pixels, enlarging these images frequently results in either blurry or jagged results as the software is forced to either increase the size of the pixel (which produces jagged results) or "guess" what additional pixels should look like (which produces blurry results).
One question I get asked frequenlty by photographers of all varieties is: "How can I increase image resolution without losing too much image quality?"Įnlargements are something we deal with every day in the world of digital imaging and output.
