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.

Not your problem... it's up to him to sort out...yes it could be a bad camera.
If you pay him for defective photos, the problem is on your end. Unless he gets it sorted out ASAP , time to hire a different photographer.

He's changed the card and the issue remains?
The problem is clearly the camera. More specifically some sort of read issue from the sensor after each shot where/when this appears.
IAC, from the problem description, it is most likely the camera in any case.

Agreed. Most likely a failing sensor, if the pics are in JPG format.

Because corrupt data in the middle of a JPG file always(*) leads to an horizontal line (for a picture out of a camera, horizontal here means "parallel to the longest side") usually followed by the rest of the pictures with wrong colors. This is very different from what is described. On the other hand, another format (some "raw" one, for instance) could store things using a "vertical" scan and no compression, in which case missing data could produce something like what is described.
(*) as far as my experience goes, but it includes several thousands pictures recovered after a hard disk crash (CHKDSK ran for 23 hours:-). -- Bertrand

I have run into this problem in Photoshop and have solved it by closing the image without saving and restarting PS. IIRC the green line is some type of margin marker. You might get a better answer in one of the Photoshop forums.

If the problem's reoccurred after replacing the media card I'd suspect a duff sensor or camera memory. I had a look around to check and turned up a few comments on the Adobe forums that may be helpful:

What the poster described however, is a vertical line along the side of a landscape image. The same direction the read of the sensor data takes place (shortest length). So most likely a point fail on the sensor that stops the bucket brigade output leaving a line behind.

I've seen that and get what you're saying. And the "usually followed by the rest of the pictures with wrong colors" is a key detail - that also makes it inappropriate to this particular problem, I believe.

Had something similar once, luckily it was a known fault and was repaired. Having seen something matching that before I'd call it a camera fault, but others may be right. I'd say that it being in the exact same place is a bit of a clue to it being in the camera though.

Yes indeed - the apparent refusal to answer my calls or respond to emails is leaning me very much in that direction.

Thanks to you fine gentlemen for your responses, which I appreciate and for which I am immensely grateful.
It seems the problem is a hot pixel on the sensor - www.pixelfixer.org shows the problem almost exactly as it appears on these shots. Photographer advised and will be using the pixelfixer tool to repair these shots - and won't be hired for further work unless he gets his camera repaired or replaced!

I have no doubt you will be able to find another photographer who knows what they are doing.
