Originally posted by Not a Number Alright, I'll give it a go in PDCU5 (which I use for the K3) although I might have encountered something similar in the past (and just I remember) with just the K5+DA*16-50 RAW files "viewed" in DCU4.
On the other hand, once the files are processed, the banding is gone in the final TIFF/JPEG image.
I'll also check for this bicubic/bilinear compression.
Thanks !
Edit: I checked the forum thread and read:
"The banding has little to do with JPEG compression and a lot to do with the 8-bit/channel color limitations of the JPEG format. Normally it is not much of a problem, but with large regions of primary color and a shallow gradient (such as the sky), 256 shades just ain't enough. Gradients appear as discontinuities.

Now, how do I know whether there has been "downsampling" or is it even important to know that.
All I know is that once the files are opened/processed via CS5, no banding shows.
Only in both PDCU 4 and 5.
