Originally posted by cats_five OK, having downloaded Fastone and had a little play I'd say that is where your problems are. I altered the RAW settings (F12) and when I reloaded having choosen the 'slow' versions, it no longer displays the banding when the image is shown full-screen. You also want to look at the JPEG quality it's showing at the bottom of the 'save as' dialog - the default seems to be 90 and it saves a lovely smooth image. However if you go into the Options for the JPG Save As and fiddle with that quality, you can make the banding come back.
NOTE: Altering the settings didn't seem to improve things until I reloaded it.
Cats5--thank you, once again, for the amazing & generous effort you have given me here. I did check settings for jpg save, which were @ "90," but I upped them to a 96. The banding still there, but the good news is I'll be loading CS 4 soon, and the problem, hopefully, will be all gone.
Quote: Schraubstock Hi
Mysteriously, I had the pixellated steps appearing in some of the clear and bright blue sky portions of some of my shots (taken with the K-7) also. At the time I remembered that the previews on the camera screen as well as the thumbnails showing on computer are actually highly compressed JPGs. I shoot raw and did not worry about it because I knew once the raw files are converted to an 8 or 16 bit per channel colour space this problem would disappear. (And it did)
Than I started to wonder why some pictures taken only seconds apart of the same sky display this phenomenon and others do not. So I started to experiment and quickly found out that (from my front door) if I point the camer in a certain direction to the sun (bright sunny day) the sky would be pixllated but if I turned on my heals away from the first shooting position by approx. 90º the sky was rendering perfectly. I could reproduce this (with the K-7) from my front door on a clear and sunny day every time.
So I think this phenomenon, which by the way seems to be to a certain degree lens dependent has, as far as the K-7 is concerned, a lot to do with the position of the sun relative to the camera sensor plane.
Now I have the K-5 and from the same position at my front door I can not replicate this strange phenomenon.
Hi Schraubstock! Thank you for this very interesting explanation. What you have written seems to best describe what I have been experiencing, off and on, for a few years now. I am grateful you took the time to relay your experience here--thank you for your help. BTW, which lens caused the problem for you?
And THANK YOU to everyone else who reached out to help me--mucho appreciate.
