Banding: causes other than camera/lens?

zfi, thank you, but i dont quite understand the use of the term 'saving' in this context. this is what i view upon download, raw or jpeg. nothings been 'saved' only 'imported'.

having said that, is this a camera issue, a LR issue, a monitor issue or some combination?

if its a LR or monitor issue, what specifically can i do to correct? ive looked through my LR preferences and dont see any reference to 'bits' at all, whether 8,16 or32...
 
I'm not a lightroom user. If I edit an image its in photoshop. There are prefs there to change and customize the bitrate.

you are shooting raw out of camera? Is there an option to set the bitrate of your jpgs? The other thread I saw was also a ricoh user. He mentioned that he didnt see any banding when shooting raw. try shooting raw, processing, then exporting 16bit png's if possible.
 
well, i just downloaded to Aperture a jpeg picture i took today that exhibited this 'banding' in LR. i fully expected not to see the problem in Aperture, but i did! same problem to the same degree in a different program!

sooooooooo.....now i think we can eliminate LR, no? is it my monitor? could it possibly be the camera?

i'm not definitive on this, but it seemed to happen today only in shots i took directly into a bright sun....
 
Somewhere along the way, did you by any chance set your jpeg output to 8 bits per pixel rather than 16?

This seems like a jpeg artifact to me. I would be interested to see if a screenshot from lightroom or aperture of the raw file shows the same banding. Also, if you output to TIFF in 16 bpp, does the banding still appear?
