Because I am new to LR, I had not noticed this post before. Or I did not go search for it.
Scott Kelby is THE reference for LR.
Yes, I like Martin Evening and his book “The Adobe Photoshop Lightroom 3 Book: The Complete Guide for Photographers“, but he does not get as much exposure as Kelby.
Scott Kelby’s post is (or course) dead on what Lightroom 4 should be.
That’s not to say that LR3 rocks as it is – and I can humbly say this as a former Aperture 3 user.
