For some time I have a problem with the before-after comparison in the development module of Lightroom. My suspicion of something “funny” going on dates back quite some time, way before LR Classic I think.
Lately, working on images with a lot of dark tones, I got worried.
I use the before-after comparison – either the sequential comparison using the “\” key or the side by side “Y” key - a lot when making the last subtle adjustments to an image.
I turns out that using the before-after comparison between two identical development states, the comparison shows a difference. I have tried to make this visible with the attached figure.
Left is “before”, i.e. the original image, right is “after”, that is after pushing the development reset button. The dark tones in the before image are noticeably lighter than in the after image. The tones in the after image seem to be the same as in the original.
I suspect that something similar goes on in the softproof mode.
Has anyone seen this kind of effect? What is wrong with me or with my system? Any ideas?
Configuration: LR Classic 7.3.1., Windows 10, display Eizo CX271 calibrated with i1Display Pro, set at 5500K, 80 cd and white-black ratio 250:1.
