I'll use this image so we can see how good of a job Preserve Details 2. You can get the latest Photoshop version here. Preserve Details 2.0 is available in Photoshop CC 2018 and later so any recent version will work including Photoshop 2023. This is lesson 8 in my Resizing Images in Photoshop series.ĭownload this tutorial as a print-ready PDF! Which version of Photoshop do I need? In order to fix this problem, there is a parameter in the TensorFlow bilinear resize that will do the half-pixel correction. This adds up the difference in the resizing method outputs. And if you still believe that you can't make an image larger without it looking terrible, Adobe and Photoshop are out to prove you wrong. This happened because OpenCV adds half-pixel corrections to the image while resizing. Preserve Details 2.0 is by far the most advanced upscaling technology that Photoshop has ever seen. It's the sequel of sorts to the original Preserve Details algorithm that was added in an earlier release of Photoshop. But Photoshop CC 2018 introduced a brand new upscaling algorithm known as Preserve Details 2.0. Depending on which upsampling method you used, your larger version usually ended up looking soft and dull or chunky and oversharpened.Īt least, that was the way it used to be. All Photoshop can do is guess at what the new pixels should look like, and then it tries to blend the new pixels in with the originals. And if that sounds like a bad thing, that's because it is. But when the image is zoomed, it is similar to the INTERNEAREST method. It may be a preferred method for image decimation, as it gives moire’-free results. Photoshop needs to add pixels to create detail that wasn't there before. INTERLINEAR a bilinear interpolation (used by default) INTERAREA resampling using pixel area relation. The smaller version usually ends up looking sharper than the original.īut making an image larger than its original size is a whole other thing. It sounds like a bad thing, but the result is just the opposite. To make an image smaller, all Photoshop really needs to do is take some of the pixels from the original image and toss them away. Or at least, you can't make it larger if you care about image quality. If omitted, or if the image has mode 1 or P, it is set NEAREST. The new file size for the image appears at the top of the Image Size dialog box, with the old file size in parentheses. Under Dimensions, enter values for Width and Height. When it comes to resizing images in Photoshop, the general rule has always been that you can make an image smaller than its original size, but you can't make it larger. This can be one of NEAREST (use nearest neighbour), BILINEAR (linear interpolation in a 2x2 environment), BICUBIC (cubic spline interpolation in a 4x4 environment), or ANTIALIAS (a high-quality downsampling filter). To maintain the current ratio of Width to Height, be sure the chain icon linking these properties is activated.
