![]() ![]() That should turn all the colour blotches to black if they are identical in the two layers. The colour blotches are identical, but since half of them are surrounded by white and the other half by black, those Photomatix processes that treat colours dynamically (depending on pixel surroundings) will produce different colours for each identical pair.Ī simple verification procedure is to position the white half on top of the black half in Photoshop and set the top layer to Blend mode Difference. To identify those settings that behave predictably we need to create two versions of the reference chart, namely one with black and one with white background. No surprise, Detail Enhancer can be one of these. Other settings produce dynamic colour shifts depending on the surrounding pixels. Long story short: Some settings in Photomatix produce consistent colour shifts and can be calibrated. Then I tried another setting and calibrated that one.I converted the TIFF output to DNG in Lightroom and calibrated that file in Photoshop as if it were a raw file from a camera.Then I simply ran this triplet through Photomatix. ![]() Note that this combination has -2 as the middle and presumably “normal” exposure.
