When using the Image Size dialog box in Photoshop, there are several different resampling options including those used most by photographers — Bicubic Sharper, Bicubic, and Bicubic Smoother. These different options have an impact on the perceived sharpness & smoothness of the resulting image. When changing image size relatively small amounts (say scaling up or down less than 10%), it may not be necessary to change the default setting of (Bicubic), but when making large changesbe certain to choose the appropriate option for the maximum quality. For example, if you have a high resolution scan and need a low resolution version to place on the web, make sure to use the Bicubic Sharper option. If you have a low resolution capture from your phone and want to resize it to print as a poster, use the Bicubic Smoother option.
