I have an old Nikon D80 with me. When I shoot with higher ISO, like 800, vertical color bands are produced in the image.

Why does it happen and is there any way to eliminate it?

Example with high ISO | Image taken at f/29, 1/160, 44.00mm High ISO Example

Example with low ISO | Note: no color banding. Low ISO Example

  • \$\begingroup\$ And have a close look at your low iso images as well (especially the darker areas). I'd expect the noise to be there as well, but of course at a lower level. \$\endgroup\$

  • \$\begingroup\$ No it's not, I'll get noise band even when I shoot at 1/00s 800 iso 4f \$\endgroup\$

Based on what I've read, CCD's are prone to producing excess noise with high ISO and long exposure. The effect you are observing may be blooming or smearing of the CCD. According to Wikipedia:

When a CCD exposure is long enough, eventually the electrons that collect in the "bins" in the brightest part of the image will overflow the bin, resulting in blooming. The structure of the CCD allows the electrons to flow more easily in one direction than another, resulting in vertical streaking.

You can see examples of blooming and smearing on Google Images. Most appear fairly obvious and extreme, but some are similar to what is seen in your sample image.

Avoid the problem by avoiding high ISOs and long exposures.
