Is this normal? White vertical lines in EOS 5D Mark IV images

Paul76 — Tue, 11 Mar 2025 12:32:11 GMT

Started to notice issues on my photos, wondering if anyone knows what it could be or is it something more serious with the camera body?

Canon 5D IV with 70-200 2.8 IS III

Was processing a few photos i took yesterday, dehazed a few and notcied white vertical lines to one side of the image.

Took a sample photo of the current cloudy day, ISO is 6400 (which is when ive started to noticed it), there is a lot of noise, i know, done this to make it easier to highlight the issue.

Share some raw files instead.

You can share a link to a reputable filesharing service like OneDrive, Google Drive, DropBox, etc.

Is it present BEFORE you applied the noise reduction to the images?

It was a few white stripes running down one side of the photos that I noticed first, did the dehaze to the max to highlight the effected area

Your posted image seems like it is a tight crop. It lacks context. This is why others are asking to see a sample. So am I.

do you notice the dark lines down the right side, from top until half way?

Re: is this normal

Peter — Sun, 09 Mar 2025 17:22:09 GMT

Yes. Share a couple of raw files.

I would like a raw sample with a shutter speed longer than 1/180 sec, preferably towards the sky. This to rule out the shutter.

I would like two pictures of a white wall inside. Exposure longer than 1 second for both, but one with Long Exposure Noise Reduction turned on and one without. This to see if a dark frame will remove it.

Please post a RAW file or two, especially this one, I see black lines on both sides running from top to bottom on multiple devices. The resolution is also quite low. Is this image a screenshot?

If you are using any lens fllters, then please remove them when you capture the images Peter suggested.

What software or workflow are you using to move or copy the RAW files from your camera to a computer? I assume that you are using a computer. Correct?

We are less interested in seeing images of the symptoms. We are far more interested in seeing images that are “straight out of the camera.” No lens filters. No JPEGs, just RAW files.

@Paul76 please follow all of my colleagues advice and add a RAW photo so we can closely look at the picture. The forum only has so much space for pictures. It cannot handle RAW images only JPEGs ONLY. @Waddizzle I have the same exact lens and camera as the OP and I couldn't duplicate the problem. So there is a setting or a physical problem with their camera.

Yes, it's a screenshot of the photo, (to be able to upload it on here).

Use Canon software to transfer the RAW to a PC.

Using Dx0 and lightroom.

I'm away from home for a few days now, so won't be able to take RAW photos of a white wall until I return.

My original post was shooting at the grey fog, at the same settings as the photo of the boat, with no filter.

As you mentioned, you have the same gear and unable to duplicate the problem, I'm suspecting the sensor failing.

For how long have you had this issue. I suspect your work flow and image processing.

First time I've noticed it, been over photos taken previously, can't see the same.

What do you mean by " work flow"?

Are you using Photoshop or any other Photo editing software. How do you get your pictures off your camera to the computer. Are you using both card slots or just one. Is the camera set to record JPEG only, RAW only or both. What kind of computer are you using Windows, Mac or both.

Re: is this normal

Paul76 — Mon, 10 Mar 2025 18:24:30 GMT

Sandisk extreme CF card.

Use the cable direct into the camera to transfer using Canon software.

Lightroom

Photoshop

Dx0

Windows PC

What version of Windows are you running on your computer. Windows 7, 8.1, 10 or 11. Could you take a picture of something that is in the RAW format. Then use the Windows File Explorer to see if it’s still a problem. Also post that picture in the forum.

Re: is this normal

Paul76 — Mon, 10 Mar 2025 18:36:52 GMT

Windows 10.

Will do this, just will be in a few day's. I'm on the road, so not home to be able to do this
