Well, instead of the negative effect (I need to the old negative of my parent I need to process), the new lightroom is very good for me !
The surprise is the lens correction, was not expecting this on this version, very large range of correction there available. And also a start for a bank of lenses by brand and type.
I will try the 30 days trial, and probably after that I will make my credit card working on that
First thing in addition so far, it is very fast compare to the 3.0 beta 2. Thank ! I will not have to change my pc.
I have never do correction on my picture for the lens effect ... but probably I will do start with some.
Instead of the lens correction, the rest of the application look pretty the same of the last beta version.
