The first bit of feedback on the Lightroom 4 Beta I wish to share is to just give me back what I had in Lightroom 3.
The new automatic chromatic aberration removal option is not good enough. It hardly does anything. Please give us at least the option of using the manual controls that are found in Lightroom 3.
This could really be a reason I would not upgrade. Or maybe keep LR3 around for chromatic aberration removal in really bad cases.
Please, please, please bring this back into Lightroom 4.
I would send it to his yahoo account with and explanation. If it's large, you could use yousendit or similar. It's email@example.com.
I suspect that it's actually axial (longitudinal) CA, since the new system is so good at getting rid of lateral (transverse) CA. Neither the new or the old system attempts to remove the axial type.
I concur. I have already run into several situations where the automatic CA control was not able to correct for CA in extreme corners. It does a pretty good job, but we definitely need the manual correction controls back, maybe even a third one like in Photoshop>Lens Correction filter, i.e., red/cyan, green/magenta and blue/yellow for even more control.
