Resampling changes the number of pixels in a photograph.

You can add or subtract pixels.

This tutorial explains resampling.

For specific instructions, go to:

• Camera Phone Resampling/Resizing: Make It Bigger

• Save for Web Resampling/Resizing: Make It Smaller.

Add Pixels

You can add pixels—upsampling.

Upsampling is also called interpolation.

For example, if you cropped a photograph, you may need to add pixels to make a quality print.

Subtract Pixels

You can subtract pixels—downsampling.

Large files take a long time to load on a web page.

Likewise, a large file in an e-mail takes a long time to send and open.

You can subtract pixels to make a file smaller for web pages and e-mails.

Next, let's look at an example of upsampling—adding pixels.
