Figure 17.22 The Emboss effect
The Find Edges Effect
The Find Edges effect only creates these weird (dare I say ugly?)
patterns by exaggerating edges, and brightening and fading
nonedge pixels. Not an effect you should approach without your
creative hat on. But used intelligently, it can yield interesting results.
Import the video clip CJ121.mov from the Artbeats folder in
the Media folder of the exercise fi les. This footage contains some
sweet CG motion graphics (Fig. 17.23 ).
Figure 17.23 The CJ121.mov
clip, at 0;00;01;16.
Apply the Find Edges effect to this footage. It will be desecrated
temporarily. But have faith, we'll overcome this visual vulgarity
very soon (Fig. 17.24 ).
