Hi Dick, your post is really about 2 completely separate topics. The color profiles and noise reduction parts of image processing are nearly completely independent, so the new color stuff has minimal impact on noise and vice versa. What you're saying here is that you're pleased with how the new profiles are impacting color, which is expected because that's what they're designed to do, but that you're not seeing improvements in noise reduction, which is also expected since we haven't changed any of the NR code and the new color profiles don't have anything to do with that.
Eric: Thanks for the response. As I read it, there is no intention to 'add' a noise reduction element to specific camera profiles (like say D3, D700 and future v. high ISO models). If I read this wrongly, please feel free to correct. Otherwise I am now happy on the subject, and can operate accordingly for any future shots of this type. Again thanks for your time.
Hi Dick, I did not intend my post to give any indication of what the future may hold with regards to the profiles. At the moment, the profiles are only concerned with color.
Eric Re: Color profiles,
I hope you can answer my question regarding initial rendering on import for my D300, which I asked in another post but got no replies. Previous versions of LR imported my raw's by first displaying the embedded preview, then to my disappointment, applied its own rendering. Now ... the initial preview is indistinguishable with the post rendered preview on import. While I'm happy with this (I like the previews - they match in camera previews), I'm confused as to what is going on and what has changed? Is it possible that the embedded preview is never displayed, and that LR instantly displays its own rendering on import?
>Is it possible that the embedded preview is never displayed, and that LR instantly displays its own rendering on import?
The embedded preview is still displayed, it is just identical in color appearance to the Lightroom/ACR rendering. I checked this by shooting RAW and jpeg. Lightroom's RAW rendering using the camera matching profiles (I used standard in Lightroom and in camera) is identical to the camera's jpeg. This is only true if you do not have extra options turned on in the camera such as the dynamic range reduction or changes to the picture style. The profiles are very good. They do have a small issue with highlights but you won't notice that when you import.
> Whilst the conversions at 'normal' ISO ratings are - as I said - stunning; the same cannot be said of those for the very high ISO numbers available with the D3; compared to the conversion of the same in View/CaptureNX. Applying LR noise reduction - by the bucket load - cerrtainly aids the definition, but has little effect on the colour differences
1. Can if you can provide a documentation for such color differences in form of a raw file and pointing out some differences caused by the conversion?
2. "Very high ISO numbers" is not very specific. I wonder if you are aware of the fact, that your camera's highest real ISO setting is 6400. The settings 12800 and 25600 are eye-wash, meant only for those creating JPEG in-camera.
