White Point, Dark Point, Auto Tone: The Simplest Move of All (The MIT 5k Dataset 5)

by Dan Margulis December 10, 2017

“And yet,” I wrote in my first book 25 years ago, “most color correction could be handled by monkeys…a numerical, curve-based approach calling for little artistic judgment…all the advanced techniques are inevitably based on these surpassingly simple ones. The by-the-numbers rules can be stated in a single sentence: Use the full range of available tones […]

The MIT 5k Dataset 4: More on Averaging

by Dan Margulis November 28, 2017

The previous entry described giving each of five independently corrected versions 20% weight to create a new, “par” version.

by Dan Margulis November 18, 2017

Those interested in quality have always been willing to spend time to get what they considered the best possible results. For some years now I have been suggesting that this is not the best approach in our field. Instead, I have been preaching that it is a better use of time to do the initial […]

by Dan Margulis November 13, 2017

The following details the procedures used in evaluating the images in this study. It is posted separately so that I do not have to repeat it every time I discuss results in the future.

The Presentation of Data: When Red and Blue Are Opponent Colors

by Dan Margulis June 3, 2016

The U.S. presidential campaign offers an interesting insight on opponent colors, and on how best to present data. The conventional way of doing it leaves much to be desired. Residents of other countries have difficulty understanding the American system, where in effect the election is always decided by voters in a small minority of states. […]

Applied Color Theory Classes in 2016

by Dan Margulis January 30, 2016

In September 1994, I took three days off from my day job in New York, and spent them teaching color correction to six people in Atlanta. We were using Photoshop 3, with no adjustment layers, no multiple undo, no actions, and computers with 16 mb RAM. Sterling Ledet gave the name “Applied Color Theory” to […]

I will now show a related use of it that can really help out certain product shots. […]
