Banding in D30 images :-(

[OU_WxGuesser]

Ok I can see some in the original on the bro. (I lied ) Seeing its ISO 1600 though, its like asking for banding and noise. Ever use a camcorder? Turn up the exposure on those puppies at night at see how much stuff ya get its insane.

Aaron

Looking at the originals, I don't notice anything. Going out of
the way to find error and then proclaiming there is error....
If you don't notice it in the original...... who cares? In any
electronics if you go out of way enough your probably going to find
something.

Noise reduction is on for me too. But I've always had it on for as long as I can remember. I made sure it was on for taking long exposure fireworks shots.

Is my cmos sensor going bad or what? Check these pics out. They
have been cropped 100% with no modifications at all. They where
converted using Breze Browser to 8bit Tiff. Sorry about the size of
these files. I wanted them to be as pure as possible.

I don't think the banding problem on the D30 should be likened to that of the EOS-1D (as some have commented). After all, the cameras have very different sensors (SMOS vs CCD etc.). Right?

What I also find strange is that the patterns on three sets of
images (mine plus the two that have been posted) are almost

Jay mine were in photos taken outside with low ISO and mostly saw it on the 75-300 lens. It shows in the out of focus backgrounds quite strongly-- http://www.pbase.com/galleries/sasc

I called Canon again today. I had called a few weeks ago because of the underexposure problem but wanted to test the camera more with several lenses. I have the underexposure, the banding and I believe the focus is off or mirror not aligned right.

Anyway as soon as i mentioned banding he said send it in to the repair factory. I tried to get supervisor to authorize a paid pickup but couldnt get one and was refered to call factory. Its a non 800 number and of course i couldnt get through to a human being on it. I left message but no one called back. For me it is very difficult to get to a UPS mail point because of time and distance. Very aggravating with a new camera.

I agree with you. I just thought it was limitations of the equipment. And I could write it off as such. But look at the photos that started this post. They look to me like enlargements of the original image and the only one you that's glaring is the 1600 ISO. So... the question is, is this normal for the D30 when pushed, or are our individual cameras somehow defective.

Right now I'm still looking for an image taken with another lens that shows the same banding, before I completely blame the D30.

The example images I posted were from mid May(brother) and early November (dog.) I noticed the one from my brother at the time and the one with my dog just since following this post. I still looking for an image that shows the same problem, but that was taken with a lens other than the 22-55mm 4-5.6 USM. Right now that lens is still a suspect.

As time permits, I'm running experiments to see if I can reliably reproduce what I saw yesterday. So far no luck. What I did a few minutes ago was took a series of 1/4 sec images at ISO 1600 is CF 1 set off and lens set to manual focus. I made sure no light was coming in the viewfinder (covered it and stood in a dark room).

This experiment did not show the banding at least not to the degree we saw in the images yesterday. If you crank up the auto level, contrast, and then hit equalize in photoshop, there is a horizontal pattern discernable but not anything like the noise that was in Rob's samples.

I tried experiments with the Microdrive running and also with the LCD on riht before taking a shot. I thought perhaps these were introduce noise that the CMOS was picking up on longer exposures.

I have another theory but I'm not sure I want to try it again. I've been leaving my D30 on top of our entertainment center, which puts it about 6 inches about the edge of a 27 inch TV. It never occurred to me that the TV might be magnetizing the camera. In the shots I took yesterday where I saw the banded noise, I had just grabbed the camera and started shooting. Normally I'm putting the camera in a bag and don't shoot for 1 to 2 hours later, so if the camera had been magnetized it would have worn off by then.

What do you guys think? Should we be more careful about where we leave our cameras?

Interesting, at first it looks like statistical quantization with different colors causing slight chromatic abebrations in the quantization, but it's blatently obvious that this runs across the entire image irrespective of the underlying data and doesn't follow the gradient of the image.

Did you clean or wipe the sensor recently? Could it be refraction through a residue on the CCD glass cover? Alternatively could it be some kind of delamination of the CCD assembly? The fringing is the kind of thing I'd expect to see.

Were you shooting with any polarizing filter at the time?

I have never used a filter. I do my filtering in Photo Shop digitaly.

You might try cleaning the CCD glass before an RTM. It's a bit of a long shot.

It would also be an interesting experiment to see how a polarizing filter affected the artifacts at different angles. That might point towards some film coating or delamination effect.

I took some test shots at 800 and 1600 in my basement with a 50mm f/1.8 and can't find any banding...... (sigh of relief at anyrate)

[Peter Lindsey50614]

I had this problem and had a long protracted discussion with Canon over it until they finally did some tests and agreed with me.

The Canon 50mm 1.4 is one of the lenses which causes particularly bad banding problems in conjunction with the D30, especially at high ISO, but only when using continuous shooting mode, for some reason.

Canon have acknowledged the problem, in fact it appears with most USM lenses but in most cases is not noticeable. The 28-80mm V USM is another lens on which the problem often appears, as well as the 75-300mm, Canon will apply a fix to your D30 for free, to reduce the problem. They have not said that it will disappear 100%. Anyway, in your case if it's the 50mm1.4 I would avoid using it in continuous shooting mode and you shouldn't have the problem.

RobL

The banding appeared in both images, with and without USM. I didn't
use AI servo because the images in question were not taken in that
mode. I ma using the 50mm 1.4 . Thanks for the input. My biggest
problem is that this wasn't happening as of 2 weeks ago when I took
shots at an indoor basketball game.

If I were you, I'd get on the horn with Canon. I have the 50/1.4
(and just took some very nice photos with it this morning!) and
have never seen such banding. Looks like your D30 is bad.

If you just purchased it, you should return it to your vendor for a
replacement. Otherwise, get Canon Factory Service on the job.

[Peter Lindsey50614]

After having this problem I kept returning cameras, I went through 3 D30s before doing my own tests and ascertaining that it was the lens causing the problem. Since most people (even with the same lens) don't get this problem, I can only assume you've been 'unlucky' with a particularly bad lens.

To come to the point, changing the camera won't help your problem. Changing the lens to a different sample of the same model may help. Changing the model of lens or avoiding continuous shooting mode will probably help.

If you send the camera to canon for the free fix, please let me know the results. I was offered the fix, but as I don't usually use the 28-80mm on which it was a big problem and I've hardly noticed the effect on the 75-300IS, I didn't bother sending the camera in.

 

[Pic-a-Tastic]

Hi!

They are taken in lowlight... shouldn't matter but it would be interesting to see if the banding appears in say outdoors photos as well.

There are quite many options in Breeze when converting, maybe you'd try canons RAW converter on the same pics and compare the results?

I have shot about 3000 pics with my D30 and never had the banding problem, mostly I use JPG ( because I'm lazy ;-)

You should check to see if this happens with other lenses.

Could you buy that polarizing filter and see what effect it has?

This is not a filter you can apply in photoshop, or at any time after the photograph has been taken. You should have one in your kit of tools anyway and they are cheap.

It is used for filtering out polarized light in a scene, light get's polarized when reflected or refracted and you can selectively eliminate or reinforce reflections w.r.t. unpolarized light depending on the orientation of the filter.
