Resampling an image
A.
Image downsampled
B.
Original image
C.
Image upsampled
To avoid the need for upsampling, scan or create the image at the resolution required for your printer or output device.
If you want to preview the effects of changing pixel dimensions on-screen or print proofs at different resolutions,
resample a duplicate of your file.
If you’re preparing images for the web, it’s useful to specify image size in terms of the pixel dimensions.
1
In the Edit workspace, choose Image
> Resize
> Image Size.
2
Select Resample Image, and choose an interpolation method:
Nearest Neighbor
Fast, but less precise. This method is recommended for use with illustrations containing edges that
are not anti-aliased, to preserve hard edges and produce a smaller file. However, this method can create jagged edges,
which become apparent when distorting or scaling an image or performing multiple manipulations on a selection.
Bilinear
Medium-quality.
Bicubic
Slow, but more precise, resulting in the smoothest tonal gradations.
Bicubic Smoother
Use when you're enlarging images.
Bicubic Sharper
Use when you’re reducing the size of an image. This method maintains the detail in a resampled
image. It may, however, oversharpen some areas of an image. In this case, try using Bicubic.
3
To maintain the current aspect ratio, select Constrain Proportions. This option automatically updates the width as
you change the height, and vice versa.
