Colour profiles is one area where I always felt Adobe Lightroom and Camera Raw could be improved a lot. Rawshooter Premium had the brilliant ColorEngine plug-in with colour profiles from colour wizard Magne Nilsen. I was never able to quite repeat these colours in Lightroom or ACR.
Until now. Fortunately Adobe Labs have come to the rescue with their much improved color rendering package. Have a look at this comparison of my Hawk Dreaming landscape, the top photo is the new Adobe Standard beta profile, the bottom photo is the standard Lightroom ACR4.4 profile.
The rendering of red and orange hues is much improved in the new profiles so if you’re a Lightroom 2.0 or Camera Raw (you need to get at least version 4.5) user waste no time, download the profiles and follow the instructions from the Adobe Labs page and enjoy much improved colours! I recommend using the "’Adobe Standard beta’ profile in the package but try them all and see what you like best.
