Problem with Sony ARW raw Files artifacts

Postby Ninno » Wed Apr 05, 2017 2:40 pm

Versione 2.2.2
After joining 3 Raw sony 5100 camera imaging (.arw), in the left and right side are obvious artifacts. It looks like a knitted wool.

Attached screenshots and original arw file to replicate the problem.

The problem does not occur with jpg files

These artifacts generate the dcraw converter. I have seen similar artifacts on the images from the Hasselband. You convert images to TIFF format in Sony converter if you can.

Sebastian...

FYI... ...even the RAW Noise Reduction option of SNS-HDR v1.4.22 would cause color cast and pixel edge problems when converting Fuji X-T100 RAF files and the minimum setting of "1" would over-soften Canon EOS-350D CR2 file conversions... ...these deficiencies were avoided when RAW conversions to tiffs were performed with a non-dcraw based converter prior to using SNS-HDR for image or image set, merging/tone-mapping.

The non-dcraw converter also gave me the opportunity to address excessive: (1) interpolation artifacts; (2) chromatic aberration/purple-fringe artifacts; and (3) chroma/luma noise.

...just a little more feedback... ...SNS-HDR is my goto for image blending and realistic tone-mapping...

Thank you for your creativity and work...
