Free PS Elements: Project St Imre Part II (removing color noise) in Elements

Version: Adobe Photoshop Elements 5.0


level: easy

Last week we started retouching the photo of a statue (of Prince St Imre of Hungary, hence the weird title) in Photoshop Elements, step by step. Each step includes learning a new trick, until—at least we hope—the result will be appropriate for publishing in a hobbyist photographer's web gallery. This is step two of the series.

Elements Tutorials - Project St Imre Part II (removing color noise)

1.Load the photo
The one we started last week by covering up the car sticking out of the bushes in the lower left corner. Today, we take up arms against chromatic aberration, mainly visible where shadowed and lit areas meet. In our case, the problem is comprised of purplish edges, primarily on the pedestal of the statue.

2. We need a fine tool!
In similar cases, when the aberration appears on less detailed areas, e.g. the edges of buildings or statues, and the saturation of the surrounding areas is low, you can safely rely on the desaturation method discussed in an earlier Photoshop article. On shadowed areas containing less colors, such as statues, shadowy tree branches meeting a bleached sky, or buildings that are grey or not too colorful, the method surely brings good results, even if not very quickly.

Select the Sponge Tool (press O) from the Tools palette. Set the Mode setting in the upper option bar to Desaturate. Yes, we'll simply desaturate these purple edges. Set a size of approximately 10 to 15 pixels, and a Flow of 100%.

3. Use the sponge
Select a sponge size of about three times the size of the problematic discoloration. You can work with such a sponge comfortably enough, particularly if you set a zoom size of at least 100% on the Navigator palette. This way, you'll notice the defective parts more easily, and you can do more accurate strokes with the sponge.

Simply start painting over the purple edges with the sponge. You'll have to paint over the areas more than once as even a Flow setting of 100% won't make all the colors vanish in one stroke. If you reach more colorful parts (such as grass, foliage, or the sky), take care not to desaturate them as well. You might want to select a soft sponge in the dropdown before the Size field. The effect of soft brushes weakens outward from the center, and therefore it doesn't mess up more colorful areas at the first touch.

This job takes more time than the automated or the filter-based features for removing chromatic aberration do, but since you're the one in control, it is much more accurate than the dumb machine. With a little practice and patience, you can get pictures totally free of color defects.

4. The difference...
...is obvious. Or so we hope. On the left, a part of the original photo, with an easily visible purplish color defect along the edges. On the right, the enhanced version. The sponge nicely made the problematic purple along the edges go. As the pedestal is almost free of colors itself, the illusion is perfect.

We’ll continue from here next time. The statue photo still has a handful of surprises. You'll still need to do quite a few things with it.
