Yes, and even if you have the additional bg samples behind your
defocused foreground bokeh is not using them.

This isn't too surprising. Your original deep data has discrete color
samples for each deep sample in places where objects overlap, but your
flattened color data has no "samples" to speak of. Thus, when you apply
your DeepRecolor, Nuke has to basically take each pixel and spread its
value out across all the deep samples at that pixel's coordinates with
no knowledge of what the original sample colors would have been.
Also, keep in mind that deep data isn't a silver bullet for depth-based
defocusing. It's important to remember that even deep images have blind
spots (unless you use tricks like telling the renderer that every object
is semi-transparent), so at a certain radius, your blur will start to
break down around the edges of overlapping objects. I'm guessing your
artifacts are the result of a combination of these two limitations.

Hi,
we are testing peregrine's bokeh in our pipeline. I would like to use
deep input for perfect defocus. With connecting the original deep read
to the node's deep input it works perfectly indeed. But when I do a
deep recolor, putting the comped rgba data to deep branch, it produces
a little halo around the sharp area, and other subtle imperfections.
The edges of the rgba look the same as the original deep input, no
blur or reformat happens there. Even if I just deeprecolor with the
flat beauty rgba, without any color corrections or other stuff, has
these halos. Anyone has idea what could be the difference? Or how to
solve it?
Thanks
Gabor
