You can see the difference in the preview box when compared to the previous example without resampling - that preview box looked the same as the original. If instead, you Enable Resampling by clicking on the Resample box, you will be "stretching" your image as you resize, causing it to lose quality. That is because the number of pixels hasn’t changed, but the pixels are now closer together. Notice in the image below how the image width and height are smaller by changing the resolution, but the image size and dimensions remain the same. If the Resample option is disabled, Photoshop WILL rearrange the existing pixels. To get started, open the dialog box Image>Resize Image and input the values you need. Each resample method takes a varying amount of time and offers a more or less precise result - try them out and get to know them.Īn image size adjustment is the most commonly used resizing option. Another option, Nearest Neighbor, works well for preserving hard edges. Bicubic works well when there are tonal gradients in the picture. You can also select the Preserve Details or Bicubic Smoother options to enlarge an image and the Bicubic Sharper option when reducing an image. The Automatic Resampling option usually does a good job. By default, it will be set to Automatic, allowing Photoshop to analyze the image, how you want to resize it and automatically choose the best resampling method. In the Resample menu, you will find all of your choices. When you ENABLE Resample, the lines will disappear, and the drop-down menu will become active. You can tell when they're linked because lines will connect all three values.
