SNS-HDR Forum

I'm just experimenting with SNS-HDR lite 1.4.22 as a preplacement for enfuse. I found strong vertical banding at an 8 pixel interval in cloudy sky regions. Since it is very severe in slightly misaligned images I suspect this is simply due to misalignment. Source images are 16 bit TIFFs converted from EOS 5DII raw files. No banding is visible in these files not even at strong contrast. Parameters are -da -natural -tiff16. Using -dd sometimes improves the situation but only gradually. I also tried feeding raw images directly to SNS-HDR using raw noise reduction with same result.

Is this a known problem? If needed I can probably prepare a test case...

If this could be improved SNS-HDR would be the very first choice for all kind of bracketed shots.

Please show me the sample images.

Sorry for being late...

Here is a 100% crop of the (otherwise unmodified) result. Source images are in 16 bit TIFF format.

Show me also 100% crop of the original image.

These are 100% crops of the three source images

Hi Erik,

i take this Source Pictures and change the exposure.
For example i take the Image _MG_1272.jpg and use with FSViewer the Autocolor.

And also there i see this vertical Banding, SNS-HDR reinforced therefore they are not visible failure of the source images.
