Dead Pixel

view profile

T. Jason Wright Photography says:

Visible in every image regardless of ISO, lens, file type, etc. Yeah I'm pixel peeping and it took many images to find it, but now that I've found it I can't take my eyes off of it!

It's visible on all images on the camera LCD screen, but it's usually invisible in a full-sized RAW. It's quite noticeable in sRAW and JPG images. That's how I found it... I shot a few sRAWs and boom there it was. Then I started looking for it and it's not hard to spot now.

I guess it's going to have to go back. I'm guessing the store won't have any on hand to swap out for me. I'll see what they say.. maybe I can hold onto it and swap it out when they get them back in stock.

If they tell me I have to send it in to Canon, it's going to be a tough call... I'd hate to have to lose it for a month.. what would you do? Send it in or deal with it?

The pixel is white. It's circled in red in the image below:

I did a lot of research and found this solution:

www.slashgear.com/how-to-remove-stuck-pixel-on-your-digit...

Unbelieveably, it worked for me!!! To clarify the instruction in the link, go to the 2nd yellow wrench icon menu and select sensor cleaning. Then click on "clean manually". It flips the mirror up so you can access the sensor. But you don't have to take the lens off or touch the sensor or anything like that. You just let it flip the mirror up for a full minute. Then turn off the camera and turn it back on... Then shoot again and see if your pixel is still stuck. For me it went away like magic!

Great tip. Thankfully I haven't found any stuck/dead pixels on my mk II, but if one of those buggers decide to appear I know how to push him back in line with the other working pixels :)

Also read that doing the same procedure excessively may actually provoke previously stuck pixels to become stuck again, so don't use this technique "just in case". Verify that you really have a stuck pixel first.

I was thinking about this last night after I did it - and I wondered if what it was doing was remapping the dead pixels out in camera as it does the procedure rather than waking them up.

Like when you do a checkdsk on a hard disk with the fix option on?

Yes I believe it is just remapping the dead pixels out, not waking them up or fixing them.

I had a whole bunch of dead pixels on my mk2, and they went away after the sensor cleaning tip... I still wonder if I should return it to the store to get fixed or not, and if I decide to return it, how do I prove the broken pixels? Any ideas?

They will come and go, had a few with mine did the manual clean with the lens cap on at ISO 100 for 30 seconds, then I took a picture with the cap on the lens to see if they were gone. If you set the ISO at higher sensitivities your going to see noise. stuck pixels are green blue and white and very bright and sharp. I've never seen them again and do a manual sensor clean without physically cleaning the sensor once in awhile just to make sure.

I never had a dead pixel with any of my cameras, I imagine they don't go away and stay in the same spot.

You have one, you are lucky, im stuck with what i suspect to be over 2,000! i called canon and they will remap it for me but im 4 days off my 4 month uni break, at the end of which my warranty expires, they suspect a 3 week turnaround so dont know when to get it done. such a crap decision as i havent even had a chance to play with my 5D2 properly since buying cos of uni.
Check my pixel damage:
(BTW this isnt noise, its hot pixels)

I had two shiny little bastards. The first hot pixel disappeared after one manual clean (2 minutes). The second after I put my camera downwards - with my lens facing down on the table - and tried again for 2 minutes... Houdini couldn't do this trick!
Thank you guys (and Canon), my mk2 is back in business!

cdphoto22 - The video doesn't use the mapping that the still images do - re-mapping won't help for video, unfortunately.

Hi all, I have a dead white pixel in video mode, tried this trick but no joy. Does anyone know of a solution to fix this problem? I really don't want to have to send my camera to canon and be without it for so long! Thanks

@haill2: If you are talking about the Canon DSLR group, well it has some ban-happy admins. It's easy to get banned from there without knowing why.

@Adamreading and T. Jason : crap I think you're damn right. This is just a remapping... Frak my 5D2 has some dead pixels too, I can't stand it ! It's only a 6 months old camera !! I feel completely fooled by canon on this one... Do you know if this happen with other brands ?

Thanks Martin! I can't believe it... these cameras cost more than 2000 €! I thought that dead pixels were not an issue anymore... I haven't heard about it for 10 years or so ! Crap.
