Calculating Levels in Lightroom

Saturday, June 26th, 2010

Suppose I edit a raw file in Photoshop with levels as follows:

black 5 midpoint 1.61 whites 171

Adobe Development and Auto Tone Algorithms

Sunday, June 20th, 2010

I shoot raw, and develop in Lightroom. (Version 2; just haven’t upgraded quite yet but I suspect the questions are the same for the recently released version 3.)
