Ring shaped haze around the sun, with color desaturation

[Andras Jacso]

Hi,

I've read a lot about SNS-HDR so I thought to give it a try.
I used one of the predefined preset (Natural) to get a glimpse what SNS-HDR could offer to the simple minded user without tweaking any of it slider.
I shot a spherical panorama in bracketed mode (-2,0,+2EV) On the zenith image SNS-HDR produced a ring shaped halo not too far from the sun with slight desaturation. Can someone tell me how can I avoid that?

I uploaded the final image and the source files to illustrate the problem.

I can't see anything in the result image what isn't in the source images already. In the middle exposure there is a turquoise ring with a less saturated center. In the low exposure it's even more pronounced. These rings are caused by your camera. Eventually they can be avoided if you shoot raw and use a raw processor with very good highlight restoration (like f.e. ACR 7).

In the case of such images is a problem with the selection of colors from exposures. Can help to use a smaller EV steps.
