Yes, in the case of images no.2 and no. 4.
The image has the correct colors in SNS when you save image in PS in a TIFF 16-bit format?
I've saved the same 16-bit image as a TIFF in Photoshop. One copy I tagged with the sRGB profile, the other I've saved as untagged.
Both images look IDENTICAL in SNS, the way it should be.
In the case of the tagged image, SNS recognizes the embedded profile and maps the pixels into the corresponding colorspace which is sRGB.
In the case of the untagged image, SNS does not see any associated profile and automatically assigns sRGB to it, which just happens to be the correct colorspace for the actual pixel values. That is why both images look identical. This is the expected (and correct) behavior.
I've also converted the same image into ProPhoto and saved it with the profile assigned. When I opened it in SNS, I got the tones/colors that I was expecting.
I have also saved the same ProPhoto image as untagged. When I opened it in SNS, the image looked darker than it should and the colors were off. In this case SNS assigned sRGB colors to ProPhoto pixels because there was nothing to tell it what actual colors those pixels should be. Again, this is the expected behavior.
SNS-HDR knows how to read, recognize and assign appropriate colorspaces with 16-bit files. When there is no embedded colorspace, SNS maps the pixels into sRGB (the way it should).
With 32-bit TIFFs it's a different story. If the image file HAS an embedded profile, SNS recognizes it as something else, or some other weird stuff happens but I can NEVER get the correct (or even 'acceptable') tones/colors if I save the 32-bit TIFF with an embedded profile.
Funny enough, if the pixel values belong in sRGB and there is no profile whatsoever, the colors and tones appear correctly in SNS.
However, if the 32-bit, sRGB TIFF does have an embedded profile (sRGB) the tones in SNS are way out of whack.
Maybe SNS isn't to blame. Maybe it's Photoshop's fault. I wish someone tried this on their system.
