Hi, I have a Canon Rebel XSI and have a slight problem. In the lower right area of SOME (yes, only some) of my images I see a bright red dot. Not too big, but enough to agitate me. What in the world is this? Can I get rid of it?
BTW, it seems to have appeared suddenly in my shots, and not gradually.

My guess would be a burnt pixel. I have one almost directly in the center of all my images, but I know where it is, so cloning it out is simple.
I don't believe there is anything you can do about it to 'fix' it. However, I could be wrong.
Mine gets worse the higher ISO I go up, at low ISO it's hardly noticible. |

Actually, all sensors have a certain number of dead pixels; they are mapped out at the factory, so they don't show. Canon can do that with this newly-dead pixel of yours if you want to send the camera in for mapping. As Mysafet says, cloning it out is easy.

| It could be a stop light in the distance. Or maybe a kid with a laser pointer. |

| Can you post a couple of examples (from different scenes)? |

| Yes, cloning out the pixel should be easy, but if you are planning to enter any DPC challenges you should check the rules first (cloning is not permitted in basic editing). |

That rule has changed. From the basic editing rules:
You may not:
spot-edit your entry, except to remove sensor dust or hot pixels.

In fact you can. From the basic editing rules:

Thought I'd resurrect this thread to ask a related question. I have a white spot in some of my images, which is clearly not sensor dust etc and I have assumed it is also a dead pixel. Strangely though it will appear in a certain series of shots, even if I'm altering settings between shots, and then disappear for a while. Then it will reappear, even when using different settings to the previous occasion. Anyone have an explanation as to why it should it would come and go like this?

I take a lot of shots that look like crap, can they map the 'crap pixels' out as well? |

I believe that's a firmware update. It's called the crap map ;O)
