Adding Noise: Smoothing Out Repair Jobs
Elements also gives you a filter for creating noise. Why do that when most of the time you
try to get rid of noise? One reason is when you're trying to age a photo: To make it look like
it came from an old newspaper, for instance, you'd add some noise.
Another common use for noise is to help make repaired spots blend in with the rest of an im-
age. If you've altered part of a photo in Elements, especially by painting on it, odds are good
that the repaired area looks perfectly smooth. That's great if the rest of the photo is noise
free, but if the photo is a little grainy, that smooth patch will stand out like a sore thumb. Ad-
ding a bit of noise makes it blend in better, as shown in Figure 13-6 . Also, if you see color
banding when you print, adding a little noise to the photo may help fix that.
