Fix Hot Pixel – Canon SLR [updated II]

After shooting with my Canon 50D for a while I realized there was a hot blue pixel in all pictures, I was about to send of my camera to Canon to get that fixed, but I was procrastinating… to send it off because I didn’t want to be left without my camera. So after some Googling I came across a very simple and harmless quick fix. I was surprised that it worked, but it did! [From comments I understand it worked for most ppl]

Hot Pixel Fix for the Canon 50D worked for Rebel XTi as well [update, from comments i understand that it works for the Rebel XSi,  Rebel T1i, rebel T2i, 7D, 5D M-II] :

– Remove the lens and put the body cap in place on the camera [not sure if this is a must]
– Put the camera in to “manual sensor cleaning mode”. It is the same for both the 40D and 50D – Press the “Menu” button, then select the middle “yellow wrench” tab, then “Sensor Cleaning” then “Clean Manually”. You will hear – the click of the mirror coming up (so you *could* be using a swab on the sensor – but don’t do that – leave the body cap in place).
– Leave the camera in this mode for 30-60 seconds, I kept it this way for closer to 60 seconds.
– Power off the camera off – you should hear another click as the mirror drops down into place
– That was it! Test the camera and see if the dead pixels are gone – they were for me.

Thanks for reading!

I still have no idea why/how this works, but it does. I was about to send in my camera to Canon to Fix this problem, but this was way easier!

[update, from comments 9-22-11]
“The red dot is known as a Hot pixel. When you turn on Manual Cleaning, the sensor is temporarily disconnected from the power to minimize static during cleaning. As a result, when power is restored the pixels are remapped and the hot pixel usually goes away.” There you have it, now you know (more less) how it works.

“In order to find manually clean function I needed to set the mode to M otherwise it wouldn’t appear in the menu” hope that helps you guys!
