I was playing with the indigo bunting and soon realised much of my image was out of sRGB gamut, so I thought I’d try perceptual intent. I haven’t used the intents in dt previously and soon realised I need littleCMS on, so did that and re-launched dt for good measure. I output 2 jpegs, one perceptual, one relative colorimetric, but I couldn’t see any difference flicking between them. There was loads of cyan on pressing the gamut button. Then I tried different display intents by right-clicking that button, but again no change. Any ideas please?
