Dead Pixels

[boccers_2000]

Hi all,

I'm confused and so, I find myself asking the forum.

Recently bought a 5D Mk II. I recently went out to take some starscapes (so long shutter speeds).

I come home, open the picture the Canon RAW converter (Photo Professional). When it opens, there are dead pixels everywhere (red, blue and green dots). But, if i leave it for 10 seconds or so, they dissapear. When I open the same picture in Elements 9, the dead pixels are not there.

Initially, I thought about sending the camera back but, if the pixels correct themselves I will just put up with it.

Anyone know what this is? why its like that?

Confused.com but just curious.

I had something similar to that myself a while back on a flash card, one i bought from ebay which turned out to be fake, is your card for sure a real one?

If it's a brand new body take it back and ask for a replacement. Take a card with you and a laptop if you can. Download Faststone image viewer and see how many pixels show up at 20 seconds exposure with the lens cap on.

My 5d2 had dozens, they replaced the sensor and remapped it under warrenty.

I bought it from MPB so will still technically be under warranty.

Im unsure if I need to do anything if the dead pixels autocorrect etc

Its totally normal, most cameras have a fair few, but they only show up in these conditions.
Lightroom maps out most of mine, though the odd one stays in the shots sometimes.

The same topic came up fairly recently:
