Today I took a short hike alongside a local riverbed. The temps were in the upper 90’s, and I’m not quite sure on the humidity level, but pretty high. Skeeters were hungry and critters were plentiful for tons of pictures, so when I thought I had enough shots I returned home to review my results only to find half my shots for some reason have these vertical lines as shown in the picture below. The only thing I can conclude is that somehow some moisture got to the sensor. The only reason I believe this is that I noticed a fair amount of condensation on the inside of my LCD screen on the camera back.
I only made one lens change while in the woods. Thinking it was the lens I again tried another one while at home and got the same results. I powered down camera, whipped the contacts off and tried it again with the same results. The lines did not start with the lens change in the woods, and I have no recollection of any external factors which would lead to something. The body was not dropped or bumped in anyway, nor exposed to any more sunlight that what would be on a normal every day hike, or sprayed with water. I used a towel to whip occasional sweat from the back of the LCD between shots.
At no time other than perhaps while I was taking the shots did it get wet from sweat, and that was whipped off ASAP. I’m wondering if this is possibly causing the condensation inside the LCD. If I was to bet though this would be from coming from my air condition at home, then going to the woods. However there was a good deal of time between my first few shots taken at 1313hrs and the shot that had the lines at 1343hrs. My camera was already out of the bag a good bit even before I took the first shot.
At the moment I’ve got the battery compartment and CF slot open as with the lens off with the camera sitting on top of my computer hoping to perhaps remove any sort of moisture from the body. I was hoping some of you could give me some insight as to what these lines could possibly be from. The first is a normal shot with no lines, and the latter two are with. Or at least they are on the original. If you cant see the lines, please take a peek at my smug mug folder where I have them posted. They start up with the three photos of water shots. http://medicdiver.smug​mug.com/gallery/319216​8/1/175832205 (external link)

And the one with lines if they can be seen on here.

From looking at the posting window I can't tell if they will show, they may only show on the original.

Thanks,

Wow, haven't seen that one before. I have no clue what would cause it. I would guess it might be a bad CF card. I would try another card. I don't think it's a moisture issue. We'll see if anyone else has experienced it before.

Oh yeah, you have to look at the originals to see the lines.

Thanks for the reply Eagle,

I tried a few CF cards, was hoping for something simple. The ISO settings was at a 100 so noise should not be an issue. I even tried down loading to 3 computers and they all showed the lines.

I've been reading about banding issues, and now wondering if this is possibly related to that. However from what I've read, banding generally occurs at high ISO settings. I would not think that on a bright and sunny day with an ISO of a 100 that I would have a noise issue.

I guess this may end up being a service call in the making. I'm reluctant to send my camera off in the mail, but having one that takes pictures of neat lil lines does me no good either.

Maybe someone will have some insight into the lines, as I have no clue. Thanks again for your reply.

Kenny

Call me crazy but I don't see anything in the shots that look like abnormal lines.

Oh yah I see 'em. Weird. Almost like you photographed a CRT TV set. Funny thing is it's not visible in ANY sizes other than the originals. This is definitely not the banding people send their cameras in for. This is MUCH worse.

To save potential helpers a bit of time, here is a 100% crop of a portion of one of Kenny's photos:

I've never seen anything like that. I have no idea whether moisture/humidity could cause that. However we can rule some things out. It's certainly not an optical phenomenon, and it is certainly not the "banding" that other people sometimes experience (which is more like a kind of patterned noise).

I would point the finger of suspicion at the sensor and/or the CF card. Have you tried a different CF card?

Thanks for the replies, I guess I should have done the crop thingy, but never seem to be able to do those correct.

Yes Ive tried several CF cards, and even on a cpl computers hoping it was a monitor glitch. I tired the camera again last night after letting it set out some, and again I get these lines.

I suppose in a day or so, I'll have to call Canon and see what they recommend. I guess its a good thing I saved my boxes...........grrrr

Thanks,

Kenny

Have you removed both the main battery and the little backup battery from the camera, and waited a couple of minutes before returning them?

It has definitely not anything to do with the CF or simething like that. Either a problem with odd/even address lines when reading out data from the sensor, or the DIGIC chip has for some reason taken a stage dive and isn't doing what it should. Hopefully a full power-off can get it up and working again.

pwm2,

I took out both batteries and still have the lines. Not sure what else to do but box it up and send it on off.

Thanks for the reply.
