D1h RAW file lines?

Hi, Roey,



I don’t have the issue with mine, but is this what you mean?

Early users of the D1 often complained about several specific problems in their D1 images: magenta color cast, a band-like pattern of noise at higher ISO values, and sometimes excessive red channel noise (which shows up as slightly mottled skies). With a correctly profiled monitor and NEF files rendered by Bibble, I haven’t seen the magenta problem others have noted. I have seen it in a few JPEG images, but it is easily correctable, and I suspect that better attention to white balance might have produced less drift. The banding noise doesn’t appear in the recent D1 I’ve used, and owners who’ve complained about it to Nikon and had their D1 serviced seemed to have oscillators replaced in the camera, which mostly fixes the problem (at high ISO values, there is still a faint pattern to the noise). Software products have appeared to take care of the problem, but, at this stage, I’d have my camera serviced if I found this problem in my D1.

Looks like there are filters in programs like Qimage to take care of the problem too:

hmm. i’m not sure if this is noise banding or what…the photos were shot at 1000 asa, so that may have something to do with it. but the image quality of the D1h is much much better than what the D1 could produce…i’m not sure if the problems correlate to one another. thanks, Wayne.

I’ve never seen anything like that, very strange, what lens/aperture did you use? Did you get your white balance and exposure bang on? – both of these thing are critical with this speed in particular. if you check out my gallery, you’ll see a boxing pic that was shot jpeg at 1600iso. Very weird effect in your pic…

no Sean, it was maybe half a stop underexposed, and the light situ was messy, half tungsten half flourescent. white balance was for flourescent. in the conversion window opening the NEF file in photoshop the lines are barely visible, but when toned they’re right there. they’re there on a lot of photos from this wedding…luckily they’re not visible except at 100%.

Hi, Roey,
I use my D1H for three years now but never noticed such image problems. Did you clean the sensor recently? Maybe you caused those streaks accidentally yourself? Perhaps it has do with lense flare? Sometimes strange things happen shooting in available light.

The lines are regular yet have that curve going on. Might it be a lens (internal reflection) or a filter causing a strange refraction? Sorry I can’t be of any more help.

I posted a couple more shots with these lines on them, these full frame and sharpened. you can see the lines a bit more clearly here, and actually follow their pattern, which is just wierd to me. i can’t come up with an explanation for this, but its definitely not optical – seems magnetic, if anything. http://www.rohai.com/nikonshot.jpg . and http://www.rohai.com/nikonshot1.jpg . they were shot with a D1h, and an old Nikkor-S 50mm f/1.4, on a Sandisk ultra II 1Gb card. anyone see anything like this before?
