Hi everyone

I'm getting a few problems with my otherwise beloved 1DS & wondered if
anyone else has experienced or managed to resolve them...

1. I process Raw files with Capture One DSLR & since upgrading from v1.1 to
v1.2 I've found a lot more "unwanted colour" in dark areas of continuous
tone. It's not fine grain noise, but rather a blotchiness. If you look at
the red channel then you really see what's going on. Reverting to v1.1 is a
problem as it's not compatible with mac OSX 10.3 (Panther).

2. Vertical lines in shadow areas - I think this has been discussed before,
but of course I'd never seen it in my files then, but I've had a few
instances of it recently.

3. Colour horizontal banding across frame seen in dark areas. Red or green
stripes across the entire frame. This isn't random & is is the same position
each time & I've even shot a dark grey card and seen it there.

It's a bit hard to discuss things like this with seeing the images, so I've
put some example files at:

I'd really appreciate any feedback, and other users experiences.

And yes, I've spoken to both Canon & Phase One, but haven't yet got any
comprehensive response.

Thanks

Matt
