![]() Option 3: If the "R" swatch is blue, the "G" swatch is green, and the "B" swatch is red - stop using that application to look at photos. ![]() It should be OK, most colour-managed applications do it this way. Option 2: If the "R" swatch is green, the "G" swatch is blue, and the "B" swatch is red, your application reads the ICC profile, but it isn't aware of the WCS tag in it. Option 1: If the "R" swatch is shown as red, the "G" swatch is green, and the "B" swatch is blue, your application reads both the embedded ICC profile and the WCS tag in it. Watch out for swapped channels in this one if your application doesn't respect ICC profiles, and it isn't aware of the WCS tag. I've used one of my ColorChecker photos and embedded that special ICC profile in it that swaps a couple of things in order to demonstrate colour management failings of some photo-related programs. It's based on an ICC profile made by Microsoft (you might have come across it as the Red Ducati test which is no longer available online). Additionally, some photo applications may also be aware of the WCS device model profile that can be contained within the MS00 tag of the ICC profile.īelow is a photo which can help you test this. Do the photo applications that you use read embedded ICC profiles? They should, if they are of any value, but strangely enough there are some that don't do that.
