Note
Make sure Resample Image is enabled, If you leave this option unchecked
in the Image Size dialog box, changing the dpi (dots per inch) does not al-
ter the pixel resolution of the image (or its storage size on disk). It only af-
fects the size of the image when it is printed.
Adjusting an image to 72 ppi usually gives an acceptable result. When you need to work
with a better, more detailed image, play around with the ppi until you have something ac-
ceptable. I recommend using a lower resolution in order to consume less memory on your
machine, but you do not want to end up with an image so small that you can't make out
any details. See Figure 2.3 for an example of a good and a bad reduction.
