Out Damn Spot

I have discovered an identical green speck at the same coordinates on every photo I have taken lately. I cleaned my lens (even though it was not visibly dirty) but that did not solve the problem. Does anyone know what might be causing this? Something on the inside of the lens? Something in the camera's processor? It's easy enough to clone out on any photo I care about since I know where it is now, but it would be nice if camera wasn't doing that. Thanks in advance for any help anyone can offer...

Sounds like a good excuse to buy a new camera to me... :-)

JK... I assume it is a digital? Does the speck appear on the cameras LCD or is it too small to see? I would have thought it was the lens, but if you have tried cleaning it... could it be a scratch? Sorry I can't be of more help, I know that would annoy the hell outta me...

It is a digital camera. When I zoom in as far as my camera will let me in playback mode (6x) I can just barely see the speck if the picture is of a blank piece of paper or something like that. Beyond that it's too hard to spot but it's there. On the computer it becomes very noticeable when I zoom in to say 200%, and it appears digitally created rather than a lens defect but I guess I really don't know that. The camera is pretty new and the lens appears perfect (and has never been touched by anything but dust or a cleaning cloth. If it was the lens I would say it has to be on the inside of the camera... I am going back now to see if it exists on the first picture I took with the camera. Thanks for responding though Sam.

If it only affects one pixel, it sounds like a stuck pixel. This means that the pixel on the CCD is always exposing, no matter what light is hitting it. There are stuck pixels in every CCD, in every digital camera. At the factory, they are 'mapped' out, so that they aren't used to create the final image, though new ones can develop over time. It should be able to be repaired by a service center if it bothers you that much.

hmmm thanks for the info Mike. I'm not sure if it is just one pixel (but when I zoom in to a few hundred % it looks like it covers a few pixels). It's nice to know that it may be fixable if it drives me nuts but since I know where it is and it's so small I can easily fix it on any image so I guess I'll just live with it. I can't seem to find it on the first picture I took so I guess it must have formed at some later date. Oh well, thanks again for the help.

What type of camera is it? On alot of the digital camera you can go into the system set- up and re-map the ccd. It is about a 1 minute project. If your camera has this capability, make shure the lens cap is on. if you do not have this on your camera, most good camera shops can do it for you. The only other thing is to have the ccd replaced and in this case it might be cheaper to replace the camera depending on the original cost.

I do not recall seeing any option like that (Minolta DiMAGE Z1) but I will check it out Clayton, thank you.

you could also create a layer in Photoshop that will automatically fit over that spot in any image you create and edit it out! Spiffy!

But what would it replace it with Bob? As it stands I just zoom in and clone over it with whatever's next to it. I'm not sure I understand how to use a layer to do that automatically when the surrounding color is different in every picture. Can you explain what you mean?

I dono, I'd have to see exactly how big this spot is and what it looks like. You could do some masking layer that simple deletes it, but that could be bad if its too big. Or if it's just a color change, you could have a layer that negates that color. At the least you can save a selection layer that will zero in on the area when you're ready to patch it or clone it out.

Well since I know the pixel coordinates it is not hard to find the spot, and it is always green so I don't think negating it would help because then it would just always be come other color. I guess I'll keep cloning it out until I decide to take in the camera. Thanks again~

It could just be a speck of dust that was floating around between the CCD and rear element of the lens at the time of manufacturing, and it landed on the sensor. I know with my DSLR's dust and specks have been a nuisance and produce a similar effect, maybe all it needs is a service tech to clean/blow the particle off the sensor inside?

I know that this is an old message. Have you tried swapping the lense 1st at a camera shop and then try swapping the camera. This will determine if it's the lense or the camera that has the issue.

I've had a similar problem with my ole Olympus - It was a burned-out pixel. It even showed green on all my images too. I found that I had to use the clone tool to really get it out correctly.

I take it then this is a dig. You might have dirt on the ccd or a cuble bad nod on the aray
