Going through my catalogue of photos, those that were taken before LR had lens correction capability have this disabled.
It would seem that enabling this is something of a challenge - just clicking "enable" does not fill in make/model, so I need to select the make.
At this point, LR can usually get the model right. Good so far.
This doesn't work if I've got 2000 photos selected because it's only available in "develop".
If I copy the develop settings, LR will copy enable, make and model of the lens. Oops.
Is it possible to *only* copy enable and make, leaving LR to properly determine the model for each lens itself?
