Severe banding in Pentax K10 d photos

Chilichoco · 03-23-2007, 07:29 AM

Hi everyone..

I had bought a k10 d about 10 days back,and took some really amazing Night shots. However, when they were printed at a3 size, there were severe vertical bands all through the photo.I had only read about this issue but was since some people also said they had no such issues with the K 10 d,I was hoping to get lucky too. Could anyone advise on this please. Also, the day shots of a building had some strange green vertical lines running parallel to windows and wall depressions. What can I do?

POst the photos with EXIF and you will get more info and or direction.

Make sure you're on firmware update 1.1 or later. The green bands were a known issue addressed in the upgrade.

and in addition, here is refernece to a toolset in Photoshop which helps with the banding if it will still be there after the firmware upgrade, so if you still see vertical pattern noise with 1.1

This whole issue of banding with the K10D makes me think that my purchase of the K100D prior to knowing that there was even going to be a K10D was a good thing.

Vertical Banding is usually only seen in underexposed photos that were pushed way past the point of reason.

I too would like to see the photos, both original untouched and final PP.

I find that some banding is still evident in 1.1, but its not green. I'm just used to it as ISO1600 noise (theres still less noise at 1600 than 400 on my Panasonix FZ30!).

Zubati Kit · 03-23-2007, 04:57 PM

cannot see it on this resized web shot, but if you have Photoshop that tool I linked to earlier could be handy for you in order to elimitate the banding to a great extent

The shot was a JPEG, NO PP DONE.

Exif :
Mode ; Shutter and aperture priority

Focal L : 28mm

Sh Sp : 30 sec
Ap : F16

EV 0.0

ISO 100

The problem with posting the pic is that it is not visible AT ALL on the computer screen. As I said,I could not see it at all till the prints as large as A3 came.
I am really wondering if the upgrade is going to be any help really.

Time for the really dumb question. (I'm good at these)

If you cannot see this at all on the computer screne, I assume you mean, even when you have the same image size as the printed version?

How do you know this is not an issue with your printer?

Hey good thought. And it does seem a possibility....
To Chilichoco. Bring your jpg into a photo editor and crank the heck out of the contrast to check the photo as well.
An example is below: With 30 sec (as you stated) night shots I've seen a lot worse. You can also split the channels to RGB and do the same to each to see if any pattern noise is there. Adusting the gamma brings it out a bit.

Chilichoco · 03-25-2007, 12:48 AM

I know it's not a printer issue since all other shots that were at fast shutter speeds did not have the vertical stripes in prints. They were only present in the long exposure shots.

jeffkroll thanks,but my Silkypix photo editor does not work. I can post the green lines shot though,if you look close you can see them running parallel to windows,or you can zoom in on them.
