• Snapshots now auto name with a time/date stamp.
• The White Balance Selector Tool’s sample area is dependent on zoom level. (Zoom in to sample a smaller area.)
• Noise reduction adjustments are always displayed (regardless of the zoom viewed).
• The Navigator panels in both the Library and Develop Module have two new options for zooming 1:8 and 1:16.
• This one isn’t new, but when using the Adjustment Brush, clicking on the disclosure triangle to the right of “Effect” displays an amount slider to increase/decrease all of the adjustments applied to that adjustment at one time.

A little confused on the wording of the last one; is that the same as hovering over the control point for a brush and dragging right/left to relatively adjust all of the sliders used with that brush?
Thx,
Mike.
Exactly Mike!
excellent ! i have not seen such idea of article before ! excellent !
White balance is awesome, I just wish there were a way to tell what colour tempuratures you were using with the tool.
For example if I shoot at night, and there is a street light that I know will be tungstun, and an interior light, and I know it’s flourecent. I can easily adjust for either one of those colours with the global white point tool, but now it’s a guessing game how to balance the other colour…. if only the local tool were more like the global tool!
David, I think you will be very happy with LR4 as there is the ability to paint color temperature with the Adjustment brush. You can check out the beta here: http://labs.adobe.com/technologies/lightroom4/
