Vertical Banding on an OLD 5D

jjjohn — Wed, 27 Apr 2016 11:03:46 GMT

In the last shots I've discovered the issue.
My firmware is 1.1.1 (latest) and two years ago I had no problem.

Can you help me?

Firmwares problem?
Sensor damaged?
Electronics damaged?

Thank you!

My first thought is your display. Not the 5D at all. Certainly not a firmware issue.

How do you view and/or convert your shots?

"Firmwares problem? No
Sensor damaged? I doubt it.
Electronics damaged?" Maybe.

How have you processed the image?
Seems like fixed pattern noise. It is visible on my 7D. Especially if I tonemap the image.

I have an email at my homepage under contact (kontakt) if you want to send the raw file to me.

I don't believe it is a display problem... on same calibrate display, all photos before 2014 don't show this issue

I applied one BW conversion and one curves levels
And, even on the raw file, the banding appears...

I'll send you a RAW file

I haven't got any yet. If your file is too big, use filedropper or sprend.

Give me 4 hours and I will be able to check at home.

This is a new shot (with a 100% crop image of the corner upper left), made a few hours ago.

The RAW FILE is here: https://dl.dropboxusercontent.com/u/63897897/_MG_9768.CR2

There's still the problem...

If that would have been my 7D, then I would have said that it was okey. But that is a 5D. I checked the pictures from my 5D and that one didn't have that pattern. Anyway, it is called fixed pattern noise.

Two things make your exposure "unperfect". You use wide aperture. The sensor can't collect all light at wide apterture. That means darker images and your 5D will boost your ISO around 1/3 EV or 1/2 EV without you knowing it. You can try to take another picture at f/4 and see if it helps.

The second thing is that your picture is 1 stop underexposed. Try ETTR.

I don't think you will be able to see the pattern at ISO 400. Always something...

Are you saying it's normal?

Re: Vertical Banding on an OLD 5D

It is normal on a Canon 7D. Because of the link policy of this forum I suggest you search for 7D fixed pattern noise to find more people with the same kind of problem.

At Magic Lantern forum they write this about it:

FPN varies based on your camera settings (esp. ISO) and temperature, and it can also change slowly over time.

5D is an old camera, so maybe time to upgrade anyway? 6D doesn´t have that at all and no banding either. If not, I found that the noise reduction in Darktable hides the problem pretty good. I suppose you have the similar function.

Anyway, try exposure to the right and be aware of the ISO boost you get at wide apertures.

Actually, I want to add a camera body to 5d, and one of my choices was just the 6d...

Thank you for the help!

I forgot one thing. Don´t think this is the case with your camera, but it is possible to get radio frequency interference. Especially with the 5D. Then it looks like this http://static.photo.net/attachments/bboard/00N/00NDgP-39605584.jpg
Wave pattern or line pattern.

"There's still the problem..."

Yes there is but hold on to the reigns there cowboy. I still believe you have a post problem more than a camera one.

Here is your shot done in ACR with just basic settings.

This is a 100% crop. The worse part is the gray truck box and the green cab. But it isn't really noticeable until I enlarge to 200%. Do you go that big? Ever? If I were you I would simply change my editing procedures.

I am not a fan, nor do I recommend anybody use or follow Magic Lantern. That is your choice, however. There can be pretty ugly results from doing so and Canon does not condone it either. If you screw up your camera with ML, it will have to go back to Canon to be repaired! Worth the risk? Not to me.

Second point if you are a 5D user, you are not likely going to be happy with a 6D. It is a lesser camera and of course only excels because of newer technology over your current 5D. It is not in the same class as the 5D Mk III which is the direct upgrade for the 5 series cameras. The 6D is Canon's entry level camera. The 5D Mk III is pro level gear.

Who said anything about installing ML?

I went from 5D and 5DII to a 6D. Very nice camera. Lighter, faster autofocus and no visible banding or visible fixed noise pattern. At least not from my camera. The only thing I miss is the joystick. I have a joypad instead. Not as fancy as the joystick.

"Who said anything about installing ML?"

You said ...........

At Magic Lantern forum they write this about it:

The mention of ML has a logical second step. That is installing it. Now it makes little difference to me if anybody wants to do so or even read their site for info but personally I am against it. It is my opinion for sure but has basis in fact.

"... 6D. Very nice camera."

I am sure it is. Most all new DSLR's are "very nice". It simply isn't in the same class as a 5 series. IMHO, again, it is a step down form a 5 series.

My contention remains the OP has a post issue not a camera issue. As sensor technology increases these types of artifacts are reduced or even eliminated. A newer camera should show less unwanted stuff.

It's all good. Keep shooting................

Is it a problem to gather information from Magic Lantern forum?

Re: Vertical Banding on an OLD 5D

ebiggs1 — Fri, 29 Apr 2016 00:11:26 GMT

As I stated, IMHO, yes. If you like it, use it. That is your decision. I am not a fan of it. BTW, I don't like DXO either.
