JimKasson Posted September 24, 2013 Share #81 Posted September 24, 2013 Advertisement (gone after registration) Well, I thought I had a solution to the green shadows problem. I figured, if it is a result of the M240's nonlinearity for really dark tones, then I could put a filter on the lens so that the green channel didn't outweigh the other two. I tried a CC30M, and found that the results, while somewhat improved, were still problematical. I looked at the raw files and found that the green channel was still higher than the other two, although the red had come up some and the blue had come up a lot (this was in reflected, diffuse sunlight). It sounds like I'm on the right track, but a stronger filter will swallow up even more light than the CC30M, and this is about low-light performance. Back to the drawing board...

jaapv Posted September 24, 2013 Share #82 Posted September 24, 2013 Isn't it simpler to correct in Photoshop? A couple of layers, a blending mask, and you are done. Link to post Share on other sites More sharing options...

That certainly works (you could probably even create a Ps Action), but I was looking for a way to get good images out of Lightroom, without the extra step. Either method will only work if the shadows are fairly monochromatic, but then, unless you're into five-stop pushes, you'll probably only notice the problem if the shadows are fairly monochromatic.
