Sorry to tease but if you, like me, were about to give up on your CV15 because of the odd colour shifts it creates on the M9 then I have a reasonable solution for you.

 

Go to the following URL and mouseover the top left of the image there, select Download Original>This Photo and get that image open in Photoshop.

 

Open any CV image taken with daylight WB and F5.6 on the M9. It must have had no filter on it and the camera needs to have seen it (whether via Auto or Manual lens selection) as a 16mm WATE shot.

 

In your image, create a new layer above the background layer. Copy and paste my image onto it and then inverse that layer (CMD I on a mac) then set the layer mode to Color Dodge. You will probably need to then go to Levels for that layer only and in the top pane drag the black triangle to the exact left edge of the histogram's black area, and the gray triangle to the right side of it. Don't worry about the white triangle or the output levels.

 

Now your image should look pretty well corrected. You can set up an action to do this easily.

 

To make it more accurate, get a totally opaque translucent white sheet such as those sold to make Lens Cast Calibrations on technical cameras and shoot frames into a bright sky at about a + 2 EV so the result is 'just' not clipped on the whites. DO this for all apertures you often use. Then use those images like you have just used mine. This will not only make your process exactly right for your aperture but also for your particular camera and lens combo.

 

It seems to work but I have asked Phase One to open up the LCC feature in C1 to Leica DNG files so you can do this automatically in C1.

 

Enjoy

ps the saving is the cost of a Leica 18mm!

Sorry, but which URL?

Which URL might that be?

 

I'd like to try this, as I like the 15 and often carry it instead of the WATE.

 

Thanks.

Sorry guys, elementary cut'n'paste error

Considering the asymmetry in your picture, I would say that it's likely to work only with your CV15 . My CV15 is even more asymmetric (visible even on the M8) and I would need to take myself the white wall picture in order to be able to play the same trick.

 

The CV15 seems to have huge sample variations . Mine is terribly soft in the bottom left corner by ex, and that affects vignetting and color drift as well.
