I have a problem with the way my Nikon D3, bought in 2008, records green hues, most noticeably in grass and other vegetation. These areas, particularly expanses of grass, tend to turn into a sort of uniform mush of a rather implausible colour. I use CS3 (mac), doing most of my processing in ACR 4.6.0 with the Adobe Standard beta One profile. My monitor is properly profiled, as is my printer. Everything else looks fine, it's just this grass issue. It's only fairly recently that I've started to notice it - a change of subject matter, perhaps. Can anyone advise? Is there some upgrade I should install that might correct this?
I don't know what camera profiles are available in your version of ACR, but with my D3 and the Camera Landscape profile in ACR 6.4.1 (running with CS5), the greens are quite vivid and have an appearance similar to what I used to get with Velvia. Perhaps you could make a custom profile with your existing software, but IMHO an upgrade to CS5 would be well worth the cost. Many improvements in PS and ACR have been made since CS3.
