I have noticed something odd with the new demosaicing methods RCD+VNG4 and AMAZE+VNG4. It’s not necessarily a problem, I am more curious as to why I observe the following phenomenon: When using one of the +VNG4 options I notice the colors become less saturated, and sometimes, of a different hue. Furthermore, if I push the threshold to 100% I would expect the result to be the same as just using VNG4, but this is not what happens.
Now, this may be by design I realize, but I am curious as to why , if so. Or is this a side effect of how the mixing is implemented? I suspect it relates to the camera having an atypical color filter array, but not sure why RCD+VNG4 at 100% doesn’t just look the same as VNG4. Again, it’s not a complaint, as it can be a useful feature when adjusting the threshold to taste. Just wondering why for the sake of knowing. Also enabling match greens doesn’t affect the outcome.
(The photograph itself is nothing special, just a random test shot I took one evening a little while before sunset)
Pictures are attached below.
RCD+VNG4, but with the threshold set to zero. Looks identical to RCD.
50% Mixture of RCD and VNG4
RCD+VNG4, with the threshold set to 100%. I would expect it to be the same as VNG4, since setting to zero makes it the same as RCD. However this is not what happens
