Ken Rockwell has responded to Nikon D200 banding issue by saying:
“It’s such a non-issue I’d never have found it if I hadn’t tried to repeat it out of curiosity. I’ve made over 3,000 shots with my D200 and have never seen this except for when I tried to reproduce it.
The D200’s non-issue happens if you severely overexpose (blow out) a large portion of the image at ISO 400. When viewed at 100% there may be a mild vertical striping, banding or corduroy effect in moderately exposed sections. You have to blow out a large portion of the image in exactly the right way to cast exactly the right striped veil over the darker parts of the image. Images that show this striping are so blown out that my grandma would be smart enough to delete them in the camera before she ever got to looking for this nuance on her computer at 100%. Even then these bands only appear under just the right combination of bad exposure. “
Bjørn Rørslett has recently commented about the banding issues on Nikon D200 in his review:
“I have identified three different kinds of striping, such as they appear visually. Now, I do not know whether they all originate from the same source. In fact, I haven’t any inside information to the underlying cause(s). All I do know is that we see a real, existing issue with some cameras. Is it serious? Maybe not on a general level, but a troubled camera could be annoying for some shots, more so because the presence of striping seems to be very unpredictable. Now you see it, now you don’t. However, when striping do occur, it typically is one of the following,
* Type I. A comb-like pattern of short, alternating very light and very dark lines surrounding smaller and often intense highlight areas, some “combing” seen also at the boundary between high-light and darker backgrounds. Often needs 200% magnification to show up clearly. Different post-processing can reduce the visibility of combing to a large extent.
* Type II. Alternating light and dark lines occurring in shadows, where they may extend across the entire area, but highlights are clean and show no trace of this. Contrast difference between lines less than in (I). Seen with studio portraits, against-the-sun shots, and suchlike setups, in which there are significant areas of highlights. May be seen already at 100%.
* Type III. Striping across the entire image frame in a very regular pattern, often clearly visible below 100% magnification and starts to show up at 33%. Less contrast betwen stripes than in either (I) or (II). Can occur with night exposures, severely underexposed images, or more unpredictably for quite normal scenes although these tend to have some contrast in them.”
