Is it really necessary to perform lens correction manually on every image in Lightroom4? I have checked the enable box and also included lens correction in my set up file. It seems to me that when photos are downloaded or even after they are downloaded the lens correction should be automatic across the board, especially since I primarily use only three Canon L lenses for 80% of my shooting. Yet, no matter whatI do, I cannot get the correct lens recognition and adjustment automatically and am forced to do each photo one at a time which is seriously time consuming. Suggestions and solutions would be very much appreciated. And, yes, I have read Adobe set up instructions, etc. but there does not seem to be any description of how to accomplish this. I am using DNG files.
No, it is not necessary to do this individually. You can do it automatically in two ways.
One is to use a custom camera default. You turn on "Enable Profile Corrections" for 1 image, then choose Set Default Settings... from the Develop menu. Then all future images will have the Enable Profile Corrections box enabled by default (and hence profile-based lens corrections). This is what I do.
A second way is to use a Develop preset (in which the Enable Profile Corrections box is enabled), and choose that when you Import (in the Import dialog).
