Anthony,

many thanks...

My experience when starting with the Merrill was that it took a long while to change habits from the pre-Merrill cameras and I still there is a way to go to get the best out of the Merrill files.

With regards to the blotching - I use ISO 100 and with careful exposure find that I can now have the chroma in SPP down/off (slider moved fully left) and have very little purple green noise.

I'm not referring to the purple noise in the shadows, I'm talking about quite huge purples areas in the skies. The chroma noise in LR5 does not affect these purple areas.

If I need to I will use the colour noise reduction (slider moved to about 15) in ACR or Lightroom to fix.

Micro contrast can be too high with some subjects - my approach after all else fails in terms of good exposure, reduction of contrast, levels adjustment etc is to increase the luminance noise reduction in ACR or Lightroom which smoothes the image.

thanks, I will try that, I always set the luminance noise at 0

WB is generally best, I find, if I make a Custom WB using an Expodisc.

I know, but I'm not a photographer, I'm a walker with a camera, I'm outside for walking and enjoy the landscape not for taking pictures, and the Expodisc starts to become too elaborate for me.

Many thanks again

I am reawakening this thread as I have just made an image that, I think, has the problem you experience with discolouration in the skies only and that is not purple/green colour noise. More curiously it is not visible n the 16 bit TIF but becomes visible when exporting the JPG from the TIF in ACR even at max 12. Curiously it seems much better if I export a JPG straight from SPP. I need to do more examination before posting findings.

Could you you post the X3F somewhere like on your site or DropBox?
