I've noticed in my pictures and videos that there is this little red dot showing up in the same place.

at first I thought maybe it was just something on the lens so i gave it good cleaning but it's still showing up..

Anyone have any idea what this is? maybe a dead pixel?

an example of what i'm talking about






the originals to those two pics are in the zoo thread.
but it's there in all my pics but you can only see it when your viewing the picture at half and full size.. if you view it at like 600 then you can't see it but anything bigger then 600 and it starts to become more noticeable.. at least to me anyway.

Could be a dead/hot pixel. Check out this thread. There is a link to a test for the dead/hot pixel there.

Thanks,

I downloaded that test thingy but I didn't understand it.

but I tried another test i found on

http://webpages.charter.net/bbiggers...t_pixels.html#

and my results were..

on this first one you can't see anything because its at 600x
but if you zoom in you are able to see 2 red dots and a few little other ones




same picture only with fill light using picasa2
so you are able to see the dots better.




So i have two red dots and a few other little ones.

is that nomral?
i read that all cameras have them and that over time can get more

any opinions on what should i do?
should i just try and forgot about it or after my brothers wedding (i don't wanna chance sending it in now and then not having it in time) should i send it in to kodak for a fix?

When you got your P850 did you go ahead and upgrade the software. If you did then there should be a thing call image calibrate in one of the menu's that you run and I believe this is supposed to help with that . Maybe someone else can help out a little more on this.

Yeah, I upgraded but I had no idea what that was for so hadn't used it
but i just used it and ran the same test again and I can't see any of the dots anymore.

so Yay! that makes me feel alot better cause those things were annoying me.


Thanks alot Richard :-)

If your P850 is like mine, you'll need to periodically calibrate the image if you take low-light images. The downside is that my P850 seems a little more susceptible to hot pixels. The plusside is that Kodak built in a way to fix them. I once had to send in my Nikon 950 to have the hot pixels mapped out. Being able to do it myself is nice.

BTW, hot pixels are fairly common in low light pictures. Astronomy buffs are constantly coming up with ways to deal with them.

I have a Kodak P850 as well, and although I've never had trouble with hot pixels, I also don't have the software upgrade in case I need to fix them. Where do I find this update?
