Adobe released its new LightRoom 2.0 for digital photo management and post processing earlier this year. One of new features is the Adjustment Brush. I was trying it on a Dell Laptop E1505 with 2GB memory, the performance was unbearably slow rendering the feature useless, IMO.
There’s a fix 2.1 RC1 available for download at Adobe’site but it’s not fast enough to use the feature either.
