How I Sharpen – An Overview

7 Comments

(I originally wrote this article way back in 2009. Some portions were revised in February 2019 to reflect changes to sharpening tools and some different ideas I have developed regarding sharpening settings. It was updated and modified again in 2023.)

I just posted something elsewhere about how I sharpen for prints and I figured I’d get some extra mileage out of it by posting it here as well. First, few disclaimers…

  • The title of this article originally referred to a “quick overview.” Clearly, it is too long for that! But there are whole books on sharpening, so by contrast I think this qualifies as a quick description. In fact, I’ve left a lot out of the description!
  • There are people with far more expertise on this topic than I have, and I have no illusions that this description represents the “right” way to do this, much less the “best” way!

The subject of how to sharpen photographs in post for print or electronic output is one that confuses many people… and a subject to which many books, online articles, and forums posts have been devoted. There are any number of ways to get the desired results via sharpening, and different techniques are called for depending upon taste, the nature of the image, and the final form of presentation: size? print? jpg? etc…

Here is a general description of what I do when I print. I’ve left some variations out of this description. The description also covers software that I use in my workflow — you might prefer something different, but you might still be able to adapt these ideas. You’ll note at least one controversial method later in the list, but try it before you dismiss it. The approach I use could well be “over-kill” if you just want to pump out a bunch of jpgs to share with friends and family or if you want to make some small prints — my end goal is good sized prints, and I work on each one rather carefully rather than mass-processing them and printing a bunch at one time.

And please understand that I’m most certainly not implying that my way is the right way. It works for me, and that people who view my prints often remark on their sharpness and detail. (And a few other things, too, I hope! :-)

Commentary

A Couple Quick Updates

PeterP wrote left a “comment” asking how I do black and white conversions. I replied with a brief overview of my approach to using the “Black and White” layer in CS4 and then working with multiple masked curves layers to fine tune the resulting image.

I returned yesterday from a four-day pack photography backpack trip into the Young Lakes area of the Yosemite back-country out of Tuolumne Meadows. I’m currently going through a few hundred RAW files and beginning to work on a few of them. Conditions in the Sierra this past week were “interesting” – meaning some pretty good sized thunderstorms every afternoon and lots of interesting light somewhat marred by occasional smoke floating up from a wildfire burning lower in the Tuolumne River drainage.

Some Thoughts on Black and White Conversion in Photoshop

2 Comments

Every so often you run across an article that offers some unfortunate advice on an important subject – perhaps it offers outdated advice or suggests a less effective technique. I saw such an article today on methods for converting color digital images to black and white in Photoshop. Sometimes seeing such an article encourages me to write something about the same topic as a counterpoint – and that is what led to this post.

I cannot claim to be the master of this conversion process, and I recognize that there are several ways to do it that are both effective and different that what I’ll describe. In addition, this will be more or less an overview rather than a detailed tuturial. IN any case, I want to offer some ideas that might be a bit more contemporary, flexible, and powerful than those I read about in that article.

Plastic Covered Window

Plastic Covered Window

Plastic Covered Window. San Jose, California. January 10, 2009. © Copyright G Dan Mitchell – all rights reserved.

Plastic covers the window of a stucco house being remodeled in San Jose, California.

This photograph was taken literally within walking distance of my home – I know this because I walked there! At first the slanting shadows dropping from right to left across the wall caught my attention. Then the interplay between the shadows and the deep textures of the stucco wall caught my eye. Eventually, I began to like the plastic sheet (obviously put there to protect the glass from paint) and the way it obscures the interior of the building. In the end I can’t make up my mind whether the photo is simply a geometric/texture study or perhaps something a little more mysterious.
