Ok, this has me totally puzzled!
Any help would be much appreciated.
-customer has external hard drive with pictures (jpegs/jpg)
-when you look at the pictures, they randomly show overexposure, fuzziness or lines through it on different pictures
-there isn't an inherent pattern to the weirdness seen on each pic i.e. on my computer pic A may be fine, then when I look at the same pic on another computer (through the same external drive), it has fuzzy lines on it or it looks like it is overexposed
-tried copying files to my computer; the same picture that was fuzzy or looked weird is now ok but other random pics (that were fine) are now bad
-did an image of the drive and transferred them back to my drive, still the same randomness of weirdly displayed pictures seen
I've tried to look at the pictures on 10 different computers, with different operating systems and each time the same picture is either bad and perfectly fine; I just can't duplicate the problem or find a pattern to the occurrence.
I would be quick to say that the pictures on the hard drive is bad BUT I just like to find the root cause to why does one picture look fine on the drive and then when I copy it to my drive or when I look at it on another computer, it is bad. And why the randomness of it?? It doesn't matter what graphic program I use, the randomness of a bad or good pictures still occurs.
And to add this, this is not just a visual on screen thing, when I try to print the bad picture, the fuzziness or overexposure is seen on the printed picture.
FYI: my jpegs/tiffs and all other pictures that aren't from the customer's harddrive are totally fine.
