I bought a Leica D-Lux 4 a few weeks ago only to find that it had a whacking great dead pixel on every shot, so it goes back, i buy a Canon 450d and low and behold this one has 2 dead pixels on each shot.:bang::bang::bang: So now i have to go back and return that one as i bought it from Currys (at least i don't have to post it!!!) I am SO hacked off! I know it's not too much of a problem but it really does give me the raging hump!! :D

So AGAIN i have had enough with DSLRS so I'm going to have to re think what i'm going to do.

Ok rant over!
 
Yes i do but that doesn't make any difference to me, i know it's faulty and thats enough to send it back. It's not even a week old.

that would be my thoughts as well...if you not happy no amount of software manipulation will make you feel better
 
*shrug* 1 dead pixel out of 10million odd- thats a pretty good record in my books. But I would probably be taking it back too :)

Every camera sensor has them - it does not make them faulty. Usually there is a special masking table for hot dead pixels in the camera firmware and they are averaged out at a raw capture time. However, usually only them can do that and update that table. You have to pop in for a service with the camera - Fixation for example can do it while you wait.

iirc with some of the Nikon cameras you can download a third party programme and do it yourself. Not that I've ever had to....
 
sods law just try another one?
 
It's going back, End Off!!

Indeed, get used to 'em...it's more hassle trying to find a camera without them than to get rid of them in photoshop(/etc) yourself. My D90 has a stuck red pixel, but it's only really evident at ISO1600+.
 
Yes I've had them in various cameras...tbh its not covered under warrantee I believe. I remember reading in the small print of the manual.
 
I've no idea if any of my cameras have hot pixels, probably if I looked for them, but I don't go looking for the problem.

If you print, they will never ever show.
If you put them on the web they will never ever show.
Only if you stare at things at 100% will you see a problem.

IMHO just enjoy the camera, and don't looking for problems that have no relavance to photography.
 
Can't say I've ever noticed them in any of my cameras... I have one on an old monitor though :)

Do you zoom in to see every pixel then?

Only for old p&s cameras. There was some software for D100 circulating that was Nikon software used by service/repair centers but it was a) illegal and b) only for D100.

If you know of some freely available tool for D200 and up - share this please as it would be a great utility to have.
 
All digital cameras are the same and in the majority of your photos you never notice them. It usually when you start taking night shots etc, but not exactly hard to get edit out 1 pixel is it ?

For the vast majority of people its not a issue and the advantage of digital outweigh film, I dread to think how much it would cost me to shoot on film today.

As PD said I do not know if any of mine have any dead or stuck pixels I do not go looking for problems, also as othrs have said 1 out of however many million is such a small % of a % that it is to be excpected, I am sure there is a number that has tobe stuck or dead before it is classed as a problem and will be looked at under warrenty.
 
The first time I took some shots of the night sky, I thought I'd discovered 3 new stars!

Well said!

:clap::clap::clap:
 
There is a way which I believe remaps dead sensors. From a Google search:

Here is the fix, I'm not going to venture any theories as to why it worked, but one page I read said they thought it "re-calibrated the sensor"... To be honest, I don't care - my sensor seems to now be working a-okay!.

Hot Pixel Fix for the Canon 40D which worked on my 50D:

Remove the lens and put the body cap in place on the camera
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.
 
Camera has gone back to Curys for a full refund so i'm feeling alot happier now.

Going to try the Lumix GF1
 
Lets hope not eh!!!!

On the canon there were what i thought were 2 dead pixels but one was a lot brighter and bigger than the other so i'm guessing it was a small cluster that had gone, maybe 4 in one block????

Now that's putting your foot down with a firm hand. :lol:

I agree with the folks that say it doesn't really matter, as in the big picture it just doesn't really affect the end result at all.

I know that there could be dead pixies on any or all of my cameras and I may never notice them. The trouble is once I do they will start to magically grow and grow until I can't see anything else in a shot at all.

So to stop this miniscule affair from getting in my (daft) head and causing havoc, I'd have to sort it or change the camera. Not sensible at all but I'd still do it.
 
I think I've probably had dead pixels on every digital camera I've ever bought, straight out of the box.

A dead pixel will be Black not bright can you show the photo
 
Probably hot pixels. 2 is acceptible and I doubt they'll take the camera back because of that. If you had hundreds then I'm sure you'd have a case, but the noise reduction in the camera should be hiding them. Does the 450D have noise reduction custom function? I can't remember if the 400D did or not.
