What is causing this?

Got a thin skin? Then look elsewhere. Post a link to an image that you've made, and invite others to offer their critiques. Honesty is encouraged, but please be positive in your constructive criticism. Flaming and just plain nastiness will not be tolerated. Please note that this is not an area for you to showcase your images, nor is this a place for you to show-off where you have been. This is an area for you to post images so that you may share with us a technique that you have mastered, or are trying to master. Typically, no more than about four images should be posted in any one post or thread, and the maximum size of any side of any image should not exceed 950 px.

Please note that image critiquing is a matter of give and take: if you post images for critique, and you then expect to receive criticism, then it is also reasonable, fair and appropriate that, in return, you post your critique of the images of other members here as a matter of courtesy. So please do offer your critique of the images of others; your opinion is important, and will help everyone here enjoy their visit to far greater extent.

Also please note that, unless you state something to the contrary, other members might attempt to repost your image with their own post processing applied. We see this as an acceptable form of critique, but should you prefer that others not modify your work, this is perfectly ok, and you should state this, either within your post, or within your signature.

Images posted here should conform with the general forum guidelines. Image sizes should not exceed 950 pixels along the largest side (height or width) and typically no more than four images per post or thread.

Please also ensure that you have a meaningful location included in your profile. Please refer to the FAQ for details of what "meaningful" is.

Hi all
I am not sure that this is the right forum to post this, so forgive me if I screwed up!

Sometimes pictures taken with my D70 exhibit a weird color shift/ change. It seems like it happens only when the color is really vivid - like the camera can't handle the saturated color. :shock:

Here are two examples - the one is of two traffic lights at a dirt track race, and the other is of a player in a rugby match - full sunlight. It has alos happened before with a bright yellow daisy, where the inside part of the flower had the same green blocks. Any Ideas??

These things are spoiling some of my few good shots! :evil:

I've never seen any photos come out of either of my d70s, looking like that. That looks like post processing that has been way overcooked from trying to rescue underexposed photos.

Looks like there's something happening in Photoshop CS there...

No post processing whatsoever! These came straight out of the camera, I just cropped the pics and adjusted the image size for the forum.

They show up like this with every viewer - MS fax & picture viewer, Nikonview, Photoshop etc! I can only add that these were shot as Jpeg fine, and not as RAW pictures. I wish I could figure this out???

You've used Photoshop CS to reise them?

Can you perhaps upload one of the untouched-by-Photoshop originals to a server so we can see?

Might have something to do with internal camera settings... although I've honestly gotta say that I've never seen a setting that will over saturate to that extent... what are you shooting at?

Tone Comp: Auto
Saturation: Normal
Hue Adjustment: 0

The bad news is that I think you guys are right - Off to Nikon service it will have to go :cry:

What will I do in the meantime? The other bad news is that I bought the camera used, and I think it is out of warranty!

I've seen that sort of problem before, but not on a camera.

Try turning Vivid off, but other than that, it seems like a camera internal problem.

Thanks, for the input. Any other ideas are more than welcome. For now I am going to reset the camera to factory default settings, format the CF card and take the camera battery out for 12 hrs.

This only happens when I take a lot of pictures - when the card is more than 50% full.

When I take ten or 20 pics, I don't recall it happening. Maybe its the card? Maybe there is a bad sector on the card which is causing the problem?

It's driving me nuts - because you don't know when it is going to happen, and as luck will have it, it's ruined most of my good shots from Friday....
Oh Well, Photography happens!

I said this on the other board, but thought I'd put it here too...

A guy on (YET ANOTHER BOARD ALLTOGETHER) heh was having the same problem...he rebooted his computer, and the images opened fine. Strange huh?

looks like corrupted image files, it usually happens when i d/l movies from the net.
however i don't know what could be causing this though.
