Let's say you want to reduce the print size of an image. By now you should be getting comfortable with the idea that as you do that, resolution will increase. So for example, if I have an image with a print size of 8 x 10 at 300 pixels per inch and I resize it down to 4 x 5 inches, my resolution will go up. It will go from 300 pixels per inch to 600 pixels per inch. Don't worry about understanding that math. Just trust me, that's how the resolution will increase. The important thing to understand is that as print size goes down, resolution goes up.

But let's say I'm giving this image to someone who says they need the image to be 300 pixels per inch, but they need it to be 4 x 5 inches. Now I have a problem, because my image has too many pixels. At 600 pixels per inch, a 4 x 5 inch image has 2400 x 3000 pixels; at 300 pixels per inch, a 4 x 5 inch image has 1200 x 1500 pixels. So I need to throw some pixels away. Resampling is the process of taking my colle...
