Maintaining Sharpness When Resizing Images
If you want to resize a large photo you have to take the correct precautions to prevent losing too much resolution. Making an image smaller can make it appear blurry if you don’t do it right. This can make the picture less clear than it should be.
This is a fairly common issue when resizing images, but with Photoshop there’s a solution.
This method will only work in Photoshop CS and CS2. These versions are more powerful in a lot of ways, so if you don’t have them I’d recommend that you invest in a copy as you may find that you will need the more advanced features.
To reduce the size of a picture without losing too much resolution go to Image> Image Size. Click on Resample Image and then pick Bicubic Sharper from the options. This will produce the best results when resizing an image as it significantly reduces the blurring of the image when you change its size.
If you want to enlarge a photograph without losing too much resolution select the Bicubic Smoother.
This tool is so useful for resizing that you may want to select it as the default so that it is automatically selected when you start your Adobe Photoshop up. To do this go to Preferences> General where you can select Image Interpolation. Here you just choose Bicubic Sharper from among the selection and it should be set as your new default.
It is important not to perform multiple resizing on an image. To experiment with image size, use a copy of the original image as many resizings will reduce the resolution of the image more than is needed. Use the copy to find out what size you want then use the dimensions on the original to keep resizing to a minimum on the image you will finally use.
