Automatically Fixing Lens Problems
Earlier versions of Camera Raw have had lens correction features, but Camera Raw can
now automatically apply corrections for common lens problems (like barrel or/and pin-
cushion distortion, or edge vignetting). It does this by reading the embedded camera data
(so it knows which camera and lens you used), and it applies a profile to fix the problem.
It's amazingly fast, and it takes just one checkbox, but what if there is no profile for your
camera/lens,orthere'snoEXIFdataforyourimage (maybeyouscannedit),orifyoudon't
like the profile (it was too little or too much)? You're about to learn all of that.
Step One:
Open the image with a lens problem in Camera Raw. Now, if you've been using Photoshop
for a while, you already know there's a Lens Correction filter found under Photoshop's Fil-
ter menu, and they've updated that with pretty much the same features as the Camera Raw
version, but it's better to do the correction here because: (1) it's non-destructive, and (2) it's
faster. So I always fix lens problems here, rather than using the Photoshop filter.
