If image appears too sharp, Bicubic is recommended. By selecting a Resampling Method, we are telling Photoshop to alter pixel information in a way that will produce the best results when reducing image sizes.īicubic (best for smooth gradients) - Very precise method that calculates the averages of surrounding pixels.īicubic Sharper (best for reduction) - Based off of Bicubic sampling and works best when reducing images while keeping detail sharper. What does this mean? Basically, Photoshop will discard any unused pixels in order to reduce the image. First, we can change the resolution by typing in 72 and then, we can change the pixel dimensions by entering 600 x 400 as the width and height.īefore hitting OK, we will want to select our resampling method. Let's say that we want to put this image on our website, so we want it to be only 600 x 400 pixels and with a resolution of 72ppi.

By selecting bicubic smaller, we are telling Photoshop to interpolate (or create new pixel information) that will produce the best results when enlarging images.īicubic (best for smooth gradients) - Very precise method that calculates the averages of surrounding pixels.īicubic Smoother (best for enlargements) - Based off of Bicubic sampling and works best when enlarging images that have high image noise. What does this mean? Basically, Photoshop will have to create new pixel information in order to enlarge the image. In this example, we increased the document width from 10" to 12" and the height from 6.667" to 8".īefore hitting OK, we will want to select our resampling method. We want to keep the 300 resolution, so all we need to do is type in new pixel or document dimensions. Lets say we wanted to enlarge this image to a 12" x 8" so that it can easily be printed and framed. Enter new pixel dimensions, document size, or resolution. An Image Size dialog box will appear like the one pictured below.Ĥ.
