I'm wondering if there is a way to enable automatic correction of chromatic aberration by default in ACR, while leaving distortion correction and vignetting correction disabled. Thanks,
Yes. I have something similar set up myself - I have just CA and Vignetting Correction on by default.
Check the box [ ] Enable Lens Profile Corrections, then turn the Correction Amounts for the features you don't want down to 0.
Then in the Setup field, select Save New Lens Profile Defaults.
