One of the useful recent technology previews Adobe has added into photoshop is the new algorithm for scaling images up: Preserve Details 2.0
As you can see from this 400% increase sample the new method makes for a much better image compared to the traditional bicubic smoother interpolation. On some images there can be added noise but this can be controlled with a preview for feedback in the Image size window.
Im very impressed with this new tool and there will be uses for this for my clients who require very large prints or need to get the best out of a cropped image over a double page spread. Credit to Adobe for adding this.
You will need the current 2018 version of Photoshop CC to use this tool, if its not visible as an option in the image size dialog then go to the “Technology Previews” tab in Photoshop preferences and tick “Enable Preserve Details 2.0 Upscale”Share this with others on your social media:
