Chapter 1
Resolution: The Cornerstone of Image Detail
Your first task in working with images is to always to capture the best image that you can.
Starting with the best capture as a photo or scan, instead of one you will just plan to “fix
later,” will save you time and give you more image to work with. The better the informa-
tion you start with, the more likely you’ll have what you need to make the best result with
less effort, in less time.
Images are built around resolution. There is a finite amount of detail in any pixel-
based digital image that you get from a digital camera or scanner. Resolution is a measure
of potential detail; the more resolution you have, the greater amount of potential detail
in the image. High resolution suggests that there will be intricate detail; low resolution
suggests that detail may be compromised.
While you will want to capture images at high resolution to retain detail, what you
really want for images when they are applied is the correct resolution. We’ll look at how
to leverage resolution in this chapter.
