I’m in the process of researching the jump from Lr Classic to C1.  I only just downloaded the new C1 Pro 20 yesterday, but I did watch a few videos.  I wanted to test an adjustment that I just couldn’t do to my satisfaction in the Lr/Ps world.

The attached image shows before and after C1 adjustments.  It was shot with an A7R III with a Zeiss Batis 18mm lens.  The images cropped to the area of interest.  The problem was a bright green flare you see clearly near the tree trunk on the right, but also in the triangle formed by the horizontal trunk and the two vertical branches in the upper center-left side of the image.  This is a difficult adjustment because the scene is complex (tree bark, twigs, …) and while the desired result is to eliminate the bright green flare, the scene also contains greens that you don’t want to distort.  Heal and clone tools are useless here.

I tried for hours to do this correction in Lr.  In this instance, I needed to adjust a very narrow hue range (the saturated green flare), but Lr HSL has only 8 fixed hue ranges.  And worse, color adjustments for colors that fall in the boundary of two of those pre-defined ranges are addressed by ganging together two adjacent hue ranges.  So you are now adjusting a broader hue range, when what you might want it to concentrate on a narrow range of hue.  That just can’t address my problem:  get rid of the highly saturated green flare (a narrow hue range) without distorting the other greens in the image.

I quickly realized how to do this with C1.  Step 1:  Create a color adjustment layer.  Step 2: Use the eyedropper to sample the most saturated part of the flare.  That defines an initial “color wedge” for the adjustment.  Step 3: Set the layer mask.  In this instance, I used 100% flow for the bright spot on the right, and a 30% flow with a light touch in the center-left region.  Step 4:  Desaturate (the green color wedge) a lot, and reduce the lightness a bit.  Step 5:  Tweek!  I adjusted the hue range of the color wedge for the best results.  That was important because I wanted to kill the saturated green hue of the flare without distorting the other greens in the image.

I can’t say you can’t do this in the Lr/Ps world.  I can only say that the C1 tools were designed in a way to lead me straight to the solution I desired.  This is a tough adjustment, and yet I got it within days of the C1 learning curve.  Bravo C1!

Another way around this is to use the color editor. Make a new layer. Brush in the area that you want to change. Go to the color editor – advanced tab.  Then pull down saturation and adjust lightness or darkness.  You can even adjust what color is affected by narrowing down the selection with the handles on the pie that is displayed.

Yes – that’s exactly what I did (not exactly in that order).

The cool thing is how immediately obvious this recipe was.
