Dead Pixels on Canon T3i/EOS 600D

[itsninja]

Hi,

I noticed that my T3i had a few dead pixels when I zoomed in so I used the remapping trick. I manually cleaned the sensors.

I noticed that at low ISO (100-1600), the dead pixels don't show up. But starting at 3200-6400 ISO, the red/white pixels start showing up when I zoom in.

Does this mean that I DO have dead pixels? Or are they just noise from low lighting (because they look a lot more obvious than noise)?

Thanks!

when you say the remapping trick.

you put the camera cap on, turn on the manual clean and count to 10 and then turn it off right?



basically this will happen with long exposures with an high ISO, natural. Though I don't recommend doing that often to the sensor, is that what your doing?

Yep, that's the trick I'm talking about.

So, it's natural for those pixels to come up on 3200 and 6400 ISO?
