    The trouble with these strong reds. With some to and fro with Andreas the conclusion is that the sRGB Gamut is just not wide enough to accommodate these reds
    so they become thoroughly blocked each end of the histogram even though they are not blocked in Photoshop.
    I have posted both here. RGB histogram is as was in Photoshop. Can't find anything that can be done about that problem!
    This is sRGB.

    I am a little unsure Colin you refer to sRGB and RGB.
    In ACR is the Color Space Prophoto and you have subsequently produced a jpeg with or without converting to sRGB? Or and the second image Color space RGB and you did convert the jpeg to sRGB?
    The first image the reds appear to be clipped, I don't understand why you could not make it not clipped, i.e. less compression of the histogram? (Contrast Saturation)

    Jon, I can't make the histogram not clipped without losing the natural richness of the reds.
    In PS I use Adobe RGB and convert to sRGB on export for web.

    As for my second image it looks like it is automatically converted to sRGB on posting so can't show an RGB but show the histogram
    which is the same as in PS

    Hi Colin, which Color Profile are you using in ACR. In Lightroom which is the same as ACR I always begin with Camera Neutral. I think Canon had one called Camera Faithful. The profile sets up everything that follows. It is easier to build up the reds than to try to lower the saturation later.

    This is a nice effort Colin. I do not understand the difference in the various color spaces, so I'm unable to comment or offer advice on that front. I do think the reds look saturated. As I'm unfamiliar with these birds
    minus a single and distant sighting in Queensland in 2010, I looked them up to get a sense of their color. Your blue seems intense compared to most other images, so I'm curious if you've generally pushed the
    colors? Regardless, I'd move the bird right in the frame so that there's more room on the left.

    I usually close down to maintain DOF across the face and head on portraits like these. I know you were at ISO 6400, but you could have easily dropped your shutter to 1/1600 or even 1/800 for a static subject
    like this.
