I've noticed blotchy shadows on the pictures taken with M8. Firmware 2.002. IR-cut filter has been used.

A sample could be found here:

Flickr Photo Download: shadows-1000243

 

RAW file was converted to 100% quality jpeg in Lightroom. No adjustments have been made.

 

Does anyone have similar experience? I can not recall this problems with older versions of firmware.

Stanislav,

 

I'm afraid I don't see any blotchy shadows in your enormous picture. :o

 

You say that the "RAW file was converted to 100% quality jpeg in Lightroom" so that is where I'd expect the problem to occur - from quantising errors/artifacts during the jpeg compression process. Especially in continuous shadows where small steps in levels will be emphasised.

 

Do you get the same blotchiness using Capture One?

 

Pete.

Here is a smaller crop of the original image.

Converted to 16bit TIFF.

The same problem. It looks like banding.

Another image and its crop:

I have not noticed it before. I'm not sure why. One possibility is that i used to use older firmware.

I, too, have a hardware-calibrated LCD and while in some areas I see what seems to be a flattening of darker tones similar to posterization, it's difficult to tell whether it's just the way the sensor rendered the stucco wall with the available light. It's definitely not something I'd worry about unless you force people to look at your images at 100% on your monitor. And if you do, don't invite me to any of your parties :)

 

I don't remember if Flickr performs additional image enhancement at original size--I know they sharpen images at smaller sizes.
