DP2m: first images, first problems

you can enjoy (I hope) the images and stop here avoiding the bla bla about technical problems

(1) My main concern regards the purple/green areas in the clouds that I obtain in highly contrasted skies.

Hello Claudio, I'll let others respond to that. Lin Evans might be able to help.

(2) My second concern is about micro contrast. In some case it is really too high for my taste, I like better the one of the original DP2. To reduce it I decrease the contrast and the presence (in LR5), but still I’m not completely happy with the results.

How about Gaussian smoothing with a fairly low radius? Assuming that LR has it. Have you tried low resolution (never medium) mode? I use it most of the time unless I really, really need high resolution.

(3) The WB and the colors are improved w.r.t. the ones of the DP2. I use AWB that I correct to my taste in SPP, but some times it is quite difficult to find a good WB. I know that somebody hate AWB, but when I try all the other WB options in SPP they are really far from the one I like (in general they have a strong yellowish cast). I never understood if there is a difference to change the WB in SPP or to use directly a specific WB when one takes the image.

There is no difference for the review image in SPP. Either way, WB is set by the values passed as meta-data in the X3F file to SPP. All the WB values are passed so, if you change the WB in SPP, it reloads the X3F using the newly-selected WB's from-the-camera values.

The image in the camera LCD may use different (faster) parameters. You can check that by comparing the X3F embedded JPEG to a JPEG conversion saved from SPP. Someone here will know how to extract the embedded JPEG. There are several methods; I use FastStone Viewer but I think it can be done out of SPP - anybody?

We seem to differ considerably as to WB (I have the SD1 Merrill). I never use AWB, which is easily fooled by many types of scene. I shoot with the in-camera WB selected to my best guess for the scene. Then, in SPP, I color-pick a neutral object in the area of interest in the captured image. I always shoot raw.
