Thanks! It may be a bug in the way JPEG and TIFF are handled internally in Houdini. 


If you save the files out to .exr format the banding is gone. See screengrab; left side is exr, saved out of Nuke, right side is the Jpeg.


Probably best to submit it as a bug to SideFx on their website:


Edit The banding appears top come from the 'Linerarize Non-Linear Images' If you turn it off, then the image will be brighter but the banding will be gone.

                   Thanks marty i could not found your "screengrab" but i appreciate your support. how it could be a bug its most simple or a basic thing(importing file for com positing). and why side effects don't want us to comp in tiff or tga , its silly.


      Anyway when i am rendering image into .exr and importing in houdini, i got increased gamma and same time not getting any COPs for color space. so solution is, i should attache with nuke or fusion only.

If you get banding after linearizing (ie. applying a gamma), then it probably means that your source data had insufficient precision (8-bit in .jpeg is insufficient). I'd be surprised if you don't get the same result by linearising the same file in Nuke.
