Ok, the title is vague at best...but after all the hard time I've given LR, I thought I needed to really commend them on an amazing job I was able to "pull" on my images....mainly with sky/clouds and some lighter scenes...WOW...makes me want to go through all my images!
(Although any time you step away from images to revisit them, you will get such a feeling as your perspective and skills have changed, regardless of the tool you use).
LightRoom 4 does an AMAZING job on developing the files.... While getting better hang of the use of White/Highlight Basic vs Highlight tone, Black and shadows......Really nice!!
So far since I started to use LR (version3), I really haven't had the application ever crash/ hang on me. I can't say that about other processors or RAW managers I've used.
And as far as the WHy part...work with it long enough and you will see why!
Enjoy!
