What Is Color Temperature ?

Of the three elements of color (luminosity, hue, and saturation), hue is the one most closely associated with temperature.  This is a psychological temperature not a physical temperature. Most people associate red with fire or blood (warm things) and blue with sky, water, and ice (cool things), where physically a blue flame is hotter than a red flame. You can identify which hues are warmer and which are cooler by their proximity to the absolute poles of red (warm) and cyan (cool) on the color wheel. When comparing any two hues you can always ask, “Which one is warmer and which one is cooler?”. Even when comparing two variations of the same hue, very often one will be slightly warmer or cooler. Color temperature is part of what creates color variety, which is one spice of life, a very important one, especially when it comes to visual communication.

The Things You Can You Do With Temperature

Many photographers think of color temperature as something to "get right" during exposure but you can also use color temperature creatively in post-processing. You can produce many compelling color effects with color temperature. You can make distant close layers feel closer by warming them and distant layers more distant by cooling them. You can make object feel more three dimensional by warming highlights and cooling shadows. You can add a warm glow that simulates early morning or late evening light. You can  You can even make day look like night, by dramatically cooling it. And every one of these moves will change the emotional tone of an image. Temperature is a critical element for communicating with color.

Lightroom & Photoshop

There are many color adjustment tools in Lightroom and Photoshop that adjust hue. Having used them all since the day they were released (or before) I regularly use four and consider them go to tools worth mastering.

Constellation XLI


Constellation XXXVII


Constellation XLVII










This is a selection of my top images of 2019.

Check back later – there will be some late entries.

This selection doesn’t reflect sales, publication, or activities on the web. It simply reflects my opinion.


The locations include Antarctica, Scoresbysund Greenland, Iceland, and Namibia.


Continuing the momentum from the previous year's experiments I combined more images from the Hubble telescope (in the public domain ) with my own exposures, expanding my series Constellation with new images of deep space as well as stars observed with the naked eye.

Fog and glassy smooth waters in Scoresbysund Greenland offered surprise "straight" additions to my series Revelation. There are many other successful exposures waiting to be finished as composites. The images I released in 2019 all have a primal quality, a felt sense of being in the presence of another consciousness.


Ideas about a living earth have been expanded to a living universe.

Where images in my Land In Land series present married views of the same land in both an overview and a detail seen by looking very closely, images in Constellation present married views of lands and the stars that surround them offering a glimpse into deep space and time. What’s beyond the object, behind the surface, and perhaps even within it shows through.

Magic Moments

We had ten straight days of full sunshine in Antarctica. Amazing!

Still waters and thick fog persisted for several days in Greenland’s, Scoresbysund.

Standing out the door on the rail of a helicopter above Icelandic rivers was thrilling.

It was a very productive year; more than 75 new works released; more than 150 new studies made.

It’s challenging to choose so few images from so many – but it’s insightful. Try selecting your own top 12 images. Try selecting the top 12 images of your favorite artist(s).
