Hello again.

Today i made some pictures of a cloudy sky and as i imported them in PS to do the "Autolevels" i can see a strange vertical line all across my picture.

It seems like a strange line made by noise, just one pixel wide, easily correctible by the clone instrument, but quite very annoying.

What could be the problem?

Here the picture ( i had to resample , was too huge :?) but the line is clearly visible.

It appears in a lot of pictures i take...not all but quite. Something wrong with my 8080? Please help me




*** Edit***

Here the EXIF info about the original picture, if can of any help :?

Not sure what that is; usually if you have a hot pixel, it will be just a dot, not a line. Hope that your sensor has not been damaged. Have you tried pixel mapping?

The instructions for pixel mapping is found on page 172 of the C8080owner's manual. Give it a shot and see if it helps.

Good luck.

Thanx for the input StevenR.

What it concerns me is that it wont appear on all the shot i take, sometimes yes other not...

Boh... i am totally lost :O

By the way i did the pixel mapping and no strange messages appears.

Now as i can (work permitting) i willshot more landscape pictures and see if that infamous line is still there.
