Colorful Skies (edited)

On the blog


Sometimes simple tweaks result in amazing improvements to an image. The photo above was the result of putting an original exposure through a simple 'S' curves adjustment, adding a very small cyan, blue, and yellow saturation boost, sharpening the edges of the wispy clouds, and a spin through noise reduction in Noiseware. That's it. The curves adjustment by itself brought out a ton of color, especially the touch of red on the bottom of the darkest clouds. This edit was all of 5 minutes and 4 minutes of that was just experimentation.


I was going to try tonemapping a single exposure as well as tonemapping three bracketed exposures but there was no need (at least not for what I was after). The clouds were moving so fast that a 3-exposure HDR would have required the whole sky to be masked from one exposure anyway. I would have been left with a tonemapped mountainside. Instead, I opted for the mountain to be a silhouette in order to put the focus on the sky.


Compositionally the image is not all that great. However, I was at my widest setting (18mm at the time) and didn't want to chop off any more blue sky. I have other exposures in which I placed the sunrise in a more ideal spot but I'm not sure I like the overall image any better. Maybe I'll post one at a later time.


This photo was taken last year in Davis Mountains State Park in Fort Davis, TX. During our week there we saw some of the most amazing cloud formations in the bluest of skies. The night skies are void of light pollution, providing beautiful views of the stars above. This of course is why the McDonald Observatory (part of the University of Texas) is located near Fort Davis. The weather is also very nice due to the high elevation (the town is about 5000' and much of the park is higher). We were there in August and it got a touch warm in the hottest part of the day but it was very pleasant otherwise.


The original exposure is shown below for comparison.
