New 5D mark ii profiles
New 5D mark ii profiles
i just received my new 5D and will be anxiously awaiting the new profiles for this camera! anyone using it yet?
I have a Canon 5DII, downloaded the NI calibration images yesterday and took photographs of them from ISO 100 to ISO 6400.
I will be building a set of profiles for testing the new 64-bit NI plug-in with Photoshop CS4 16-bit images.
My goal will be to determine if NI still does a better job at noise reduction than CS4's native noise reduction routines.
I do not believe anyone has done that yet... I will report my findings here.

I finished creating camera profiles for the 5DII for all ISO values from 100 to 6400 made from a printed NI calibration chart that I photographed in RAW. There are 19 profiles in all.
The images were converted and opened in CS4 in colorspace ProPhoto RGB and as 16-bits.
I have the profiles zipped and you are certainly welcomed to them but I am uncertain of their value to you given that you are using a different plug-in from the one I generated mine.
Email me at azleader@yahoo.com if you would like me to send them anyway.
Here is what I know so far:
1- 64-bit NI outperforms CS4's native noise reduction routines.
2- In pure default mode 64-bit NI does a visibly better job at noise reduction than CS4.
3- 64-bit NI runs 7+ times faster than CS4. CS4 is dog slow!
4- The 5DII has noise at every ISO level that benefits from NI.
These conclusions are based only on runs I made against the idealized NI charts and not against "real world" images. I don't really expect there to be much difference but that is a test I have yet to perform.
I might also add that the amount of noise at low ISO levels for the 5DII is quite low, but that there is enough that I could see minor improvements when NI is applied while being viewed at 100% crop. Most of the time, though, in practice you probably will not need to run NI against ISO images below 800 or 1000.
