Digital photo problem - equipment failure?

[Here's Johnny]

Hi all,

I am not a photographer (though very interested in photography!) but I do
fairly basic digital retouching for wedding customers. I have received a few
discs of photos from the same photographer a few times now with the same
problem.

About a quarter from the left border of a landscape image, a vertical,
single-pixel greenish line run through. I've zoomed in and can see a small
(maybe 2x2 pixel) white spot about 5 pixels from the top of the image, and
the green line runs vertically down from there, right to the bottom of the
image. This littel white spot looks like there's a "hole" in the image,
which is "leaking" the green line.

Can this learned forum please advise me as to why this keeps happening?

I have raised this previously with the photographer and he told me last time
it was down to a corrupted media card. That sounded wrong to me, as an IT
support pro - if the media card was corrupt, we would be having other
issues. (That's not to say he was being dishonest - he's not an IT person.)
He told me he ditched the faulty card, but here we are again. I suspect he's
mis-diagnosing the problem, and that ditching this data card too will not
fix the issue.

Could his explanation be right? I suspect it's a problem with his camera and
that he's giving me excuses to fob off having to spend money on it. I'd be
very grateful for advice, as I don't want to dismiss him if I'm wrong. He
tells me he took many more photos after the ones he took for me, and none of
them have this issue, so he reckons it's ot the camera. Then again he never
noticed this the first time, nor this time, until I raised it with him.


Thanks for reading this!

Is it in the direction of the sun or a very bright light? If so, its an artefact
of CCDs and digital cameras. Point a digital camera at a very bright light
source, like the sun, and you'll get a vertical line. Different cameras have
different colours but the cause is always the same.

Would that it were the solution, but 'tain't. Sadly this is ahppening in all
lighting situations. Every pic has this, well, every one I've zoomed right
into.

Hmm ... it might be something different then. But you can confirm my one by
pointing at a bright light source. However, the vertical lines are wider than 1
pixel. They're usually as wide as the size of the image of the light.

If the line is only 1 pixel wide and happens in the exact same location with
every shot then it might be a hardware fault with the CCD itself. If you can put
up a sample image somewhere, maybe someone can confirm this. A hardware fault
would mean replacing the CCD. It would help if the camera's still under warranty.

The photographer mentioned some time ago wanting to buy a new camera, so I
doubt it. He often gets dust on the sensor when he changes lenses, and is
getting a new one which does some kind of magical magnetic shimmy to clean
the sensor automatically. Or something.

I think I'll check out photobucket or something. These are 1-2MB files
though.

What's the brand that he currently has? I would have thought that it'd have a
cover that drops over the CCD while the lens is being changed.

I searched too (see other post). Not much out there by way of faulty CCD images.

Here's one such pic. The green vertical line appears across the
left-hand collar of the leftmost gent. This is from the set I'm talking
about!

I had to download the image and zoom in to see it. It appears its a damaged
pixel on the CCD a few pixels from the top. That affects the rest of the column
of pixels. I gather its more pronounced depending on the background colour.

If the camera's out of warranty, tell your friend he can either try getting the
CCD replaced or buy a new camera.

Hmm ... it helps when you know the right term. Google throws up a lot more info.
This page explains the issue in some detail -

Its not really a hardware fault, per se, but a problem that develops with time.
