I saw a Shake demo. There, they made a branch,

8bit BW image -- blur -- emboss

the result image became ugly.

and they connected "byte node" and changed mode 8 bit to float - it's just bit depth converter in cbn2 - between image and blur, Shake created very beautiful gradation.

but when I tried it with cbn2,

8bit BW image -- bit depth converter (float) -- blur -- emboss

I could not find any difference between 8bit and float.

anybody knows why?

Thank you,

Well I will let the Shake manual explain it

Shake recognizes and maintains the bit-depth of incoming images ?

Thank you for your info.

But Why combustion cannot do the same thing? combustion also has "bit depth converter", almost the same as Bytes node.

I don't know exact reason but after upgrading to 2.1.1, I could get suitable results.

any way thanks all.
