I’m finally starting to slow down a little bit and try to concentrate on learning more about the software that I use to process my photos. Rather than cranking out a lot of so-so shots, I’m trying to pick one shot (or one set of brackets) and play around with the various options in Paintshop Pro to compare the results of various techniques. Tonight I started trying to figure out how to use adjustment levels in my processing.
I ran across a great blog called HDR Cookbook that is authored by Klaus Herrmann, who turns out some of the most beautiful HDR images I’ve seen. The HDR Cookbook is filled with some very useful information that is very helpful to beginners like myself. One of the first chapters discusses workflow, and I found some extremely helpful information in there about using levels to separate each tweak to the image so that the original image is untouched. The tutorial is written for the Photoshop products (including Adobe Camera Raw), which I don’t own, but I was able to translate a lot of the information to Paintshop Photo Pro with no difficulty.
One thing that the Cookbook talks about at the very beginning is a phenomenon called “chromatic aberration” (CA). This is the purple fringe that sometimes shows up when there are areas of high contrast in a photo. I hadn’t had to deal with that problem until I started processing HDR’s from the snow shots from this past weekend. The Cookbook recommends using Adobe Camera Raw to remove the CA. Since that software isn’t in my arsenal, I tried using the Photomatix option “Reduce Chromatic Aberration” during the HDR process, but it didn’t appear to have much of an effect…the purple was still there. Of course, you have to zoom in close to see it, but now that I know it’s there, it will haunt me.
Anyway, I did the best I could with this shot, playing with separate layers for Topaz Adjust, DeNoise, Curves, and Saturation. I couldn’t figure out how to create a separate layer for sharpening, so I applied that step after I merged the layers. The great thing is, I still have all the original image files and I can go back and try this over and over until I get it right as I learn more about the process.
So, here’s my shot for today…snow on the roadside rocks. Enjoy!
Nice image, Zann. I like the warm color of the rock against the surrounding whites, grays and greens.
