JPG Corruption?

[gstark]

Ok ...

I am shooting on the D300 using raw + fine jpg.

Occasionally, I am seeing some corruption in my jpg files, within Capture NX.

For instance ...



I've seen this about three times so far. The second form of corruption seems to be a partially processed image where I will see a small section of the image correctly, but most of it seems to be covered in a layer of green.

The third form seems to be a transposition of a part of the image, moving, say, the rh third of the image to the left, with the rest of the image then misaligned towards the right of that.

I can't find examples of these at the the moment, and it's not a serious problem because the NEFs are fine, which permits me to recover the images at will, but I'm wondering if this is (a) an issue that others may have seen, and/or (b) an issue that's occurring with using jpg fine?

Any thoughts, people?

Anyone else shooting raw + fine?

2000 shots down, haven't come across that issue yet. btw: have you used the AF fine tune feature ? what are your thoughts ?

No; I've not yet seen a need to.

Any issues that I've seen WRT the softness of images have all come back to user error.

I have had a brief play with the 3D AF though ... interesting. Could be very useful for sports.

sounds like software problem. Gary iv'e had many a tiff, jpeg etc screw up for no apparent reason. Go back to the original and all is good. As they say software is not perfect and thats a fact.

Might I suggest the obvious and say try using a different brand and size of CF Crad.
If you have had 3 corrupted, are they on the same card or different cards?

Jethro,

My thoughts have been along the lines of a firmware issue, but Biggzie, good suggestion. This far I have only been using the one newly purchased (for this camera) card. I have another brand new card that I can try, and so I shall.

While I mainly see this manifesting itself within Capture NX, it may well be something on the card, and perhaps in just one particular area of memory on that card. That, of course, will be very difficult to specifically diagnose.

Gary,

Have you tried formatting the card within the camera? I had this issue with the D70 before, but I did an in-camera format, problem solved.

Hope that works for you...

I only format my cards in the camera, so that isn't the issue in this case. Thanx for the suggestion.

I found that 1 of my cards just wasnt compatable with my camera and gave intermittent corrupt photos, but that card works perfectly in my PDA and other devices.
1 of my friends was having similar problems with his Canon SLR and asked me my advice because the shop wasnt helping him, so I lent him 1 of my CF cards, and it worked perfectly, so he seemed to have a card incompatability too.
