I don't know about you, but I can never remember when to use bicubic sharper and when to use bicubic smoother. Here is a mnemonic I came up with to help me remember:
- Bicubic smoother is better for upsampling and it comes first in the menu. It's up above sharper.
- Bicubic sharper is better for downsampling and it comes last in the menu. It's down below smoother.
In Preferences > General, you can specify which interpolation method is used as the default when images are resized through the image size command, or when transforming layers.
