About interpolation methods


When an image is resampled, an interpolation method is used to assign color values to any new pixels it creates, based on the color values of existing pixels in the image. The more sophisticated the method, the more quality and detail from the original image are preserved.

Photoshop Elements provides three interpolation methods:
  • Nearest Neighbor is the fastest but least precise method. This method is recommended for use with illustrations containing non-anti-aliased edges, to preserve hard edges and produce a smaller file. However, this method can result in jagged effects, which become apparent when distorting or scaling an image or performing multiple manipulations on a selection.
  • Bilinear is the medium-quality method.
  • Bicubic is the slowest but most precise method, resulting in the smoothest tonal gradations.
