Anti-aliasing and Resolution
The scale of anti-aliasing is tied to resolution. Holding all other variables constant, increasing the
number of pixels in an image makes the effect of anti-aliasing more subtle. Let’s take a look at an
example of this phenomenon.
1. Open the file Linework2.psd from the CD (see Figure 1.8). This file is similar to the Linework.psd
image you have been working on except Linework2.psd has greater resolution.
