Davide Barranca’s ‘Decomposing Sharpening’

Dan Margulis is The Man

I’ve been dabbling in the Dan Margulis’s Picture Postcard Workflow since serendipity landed me in Dan’s session at Photoshop World Boston in 2006. Dan’s methods and his teaching style are unique in their depth, usefulness, and results. They’re not easy to pick up casually, though. Davide Barranca posted this on
Dan’s Color Theory Yahoo Group, and I’m linking it here for my own reference as much as anything.

Actually I got carried away with it and wrote a four articles series (called Decomposing Sharpening) on that very topic on my blog. Not that all that bandwidth is required to understand what I’m doing – let’s say I’ve happily dug into the subject. A schematic index is as follows:

#1 Introduction
PPW Sharpening, Halo Maps, Blending Modes

#2 Mistakes
Why the obvious (Darken / Lighten, double Smart Filters) fails

#3 Workaround
Setup for RGB/CMYK images (Subtract adjustment layers, cascading blending modes)

#4 The Lab way
Setup for Lab images (Smart filters, visualizing Threshold, Blending mode boosters)
