Some D1h Images heavily .Posterised

Dave R
I was recently looking at some old images shot with a Nikon D1h and for some reason Capture One 8 heavily posterises some of them. Here is an example
http://m9.i.pbase.com/g9/05/376205/2/158026069.zMKiW2DM.jpg
One thing I notice is that if I examine the histogram of the affected images the red channel shows as pushed hard to the right and saturated, in unaffected images the red channel shows normally. If I examine the affected images in RAW Digger the red channel is not saturated and is in fact futhest of the four channels (Red, Green 1, Green 2, Blue) from saturation. This behaviour only shows up in Capture One 8.
Anyone know what is going on?
Is there a cure?

    I have no idea. I just imported a couple of folders of D1H images and saw no issues. Is it possible some other program modified the original files?

    Similar looking images have been posted in earlier thread. I'm not a Nikon user so have no link for them saved.

    Try a search of some sort to see what comes up - there may be some guidance in the accompanying posts.

    HTH.

    That is a good point, I did try out NX-D on a few files and after discovering that it was a total load of rubbish rapidly removed it from my machine. I don`t know if these files were amongst those I tried but I get your point that NX-D writes thing to the RAW files and could corrupt them.

    Ureka!! I just happened to have backed these files up to DVD years ago. I have reloaded the original files, deleted the capture one subdirectory launched Cature One and the problem has gone away.

    Conclusion beware Nikon software especially when Silkypix is involved.
