Hi guys,

I have an issue with my EOS 6D, beside some spots on the sensor, the ones that give dar areas on the image, of diffrent sizes, I have several X type dots, like the two attached and am very curious if you ever saw anything like it.

I will get my sensor cleaned at a professional center but from my logic these look like things that don't get solved by a cleaning procedure, and are rather some electronic faults.

I have some pixels that are turned on on some specific colours, like blue or purple, but these X pixels are something I never saw before.

So, if you know, please tell me if there is another sollution, other than replacing the sensor - wich might not be worth the money for this camera.

Thanks in advance.

Hi. The ISO of the affected shots varries between 1000 and 5000, but the problem is the same.

The answer that I accepted as sollution said that that is a center pixel, but in jpg conversion it tryes to solve it out, and as a result I have the X marks on the photo.

I will get the sensor cleaned, for some other dirt spots, and will keep solving these in post, until I get another camera.

I have another identical 6D, a rather younger sibling, and that one has no such issues 🙂 - this is my backup camera.

 

Thank you, and thank all for the help.


Easy to check in RawTherapee. Just open the raw file in RawTherapee and choose None as demosaicing method. Or just upload the raw file...

They do look like hot pixels. The reason they look like an X is the extreme blow up you are viewing it from. Try this.

Step 1 - Remove the lens from your Canon camera
Step 2 - Put on the camera cap (do not leave your camera open).
Step 3 - Turn your camera on. Go to the menu and select "Sensor cleaning".
Step 4 - Turn the dial to select "Clean manually".
Step 5 - Select "OK" and then press the "Set" button. The mirror will lock up and the shutter will open. Allow the shutter to remain open for at least 30 seconds. As long as 60 seconds is OK.
Step 6 - Turn your camera off and reattach the lens. Take a test shot.
