Problem on image

[Franco50]

i am trying a copy of your software, but how can be seen, this is the result after having treated a single photo on sns-HDR, what happened at the sky? Thanks

Hi Franco50,

could you please share the source images?

Sorry, i don't understand what you want. May be the raw file?

[Raiko]

If you can upload the raw file, we can try to check what is the reason of your strange sky.
Only to see your SNS-HDR Results, it is difficult find the reason.

This is the RAW file

Hi, i use you RAW Image with the Night Preset.
And adjust this Profile a litle bit, and don't see any strange sky like you upload.

Noticed the following regarding your RAW file data:
...ISO = 800
...in-Camera Sharpness setting = 5

Using Canon's DPP, the un-edited RAW file image has a 16 to 237 Luminosity range; a Sharpness setting = 5; a Luminance noise reduction setting = 3; and a Chrominance noise reduction setting = 3.

As the image has significant Luminance/Chrominance noise in the sky image areas at this ISO and Sharpness settings and Version 2 of SNS-HDR no longer has a Raw Noise reduction feature... ...perhaps you could develope the image using Canon's DPP settings of:
...Sharpness = 2
...RGB Curve settings = 16 and 237, expands image to full 0 to 255 tone range
...Luminance noise reduction = 7
...Chrominance noise reduction = 4, then
...Convert and 'Save as' to a 16-bit tiff image version.

Use this image version as the Input or Source image for SNS-HDR with a preferred Preset and restore Details and Clarity to a preference with the settings possible on SNS-HDR's Home/Pro Advanced tab...

Like Raiko, a modified Night preset seem favored and I was also unable to produce the sky image area artifacts you illustrated from the RAW file posted...

Addendum:
Illustrated are Advanced Tab settings to minimize adding Details and Clarity to the image's Cyan to Blue hue range [the sky image areas]. Work Space shown at a 1:1 Zoom.

Question...

Does the SNS-HDR Pro Demo version apply a 'weave' texture as well as the program name in its watermark?

If this is the case, you could use SNS-HDR Lite, currently version 2, with a Night preset to convert from RAW and tone-map... ...then use noise reduction if desired from another image editor.

P.S. I would have downloaded/installed the demo version to see but did not want to overwrite my 'official' version... ...A 'How to' for SNS-HDR Lite is here: http://www.l7.org/IMAGEs_by_DEN/tutorials7/SNS-HDR_Lite_2/SNS-HDR_Lite_2_References_170405.pdf
