      Nope, everything set to zero with linear tone curve in ACR. These are Pat s files, but they were raw files. I remember having ACR problems with blue LEDs

I remember having ACR problems with blue LEDs inside the Dragon SpaceX capsule when we were shooting a pano there and when I tried it in Silkypix everything came out fine. But I do not have Silkypix at my current location.

            I recently had that problem when stitching images from a customer who had set his white balance in the camera to auto. If you use your own ride value in ACR everything should be fine.

              You do not say what camera you use. In ACR you can change the profile. Standard is usually set to Adobe but most cameras has several different profiles to choose which give very different colors.

              Also what version do you use. The CS6 ACR 7.1 is fantastic for highlights. No clipped highlights any more like you have in your test if you use the highlight and the white sliders correctly.

                  Hans,

                  I have not upgraded yet and use CS5 at the moment. This was from a bracketed series. In this particular example I can ignore this over-exposed one, but in others that Pat shot I will need the over-exposed brackets and the sky looks the same on all the over exposed skies. He was using a Canon T3i and the Sigma 8mm I gave him a few years ago.
