Glitchy Images From My D750

Having an issue with my D750 that resembles a focal-plane shutter glitch, except the poles in some of the images are slightly out of alignment. See photos below. Nikon says my camera is also affected by the Lens Flare Issue, and I am going to send it in. This looks to be something more, however. Any expert opinions on the subject?

That's not the lens flare issue. It appears one of the curtains is synced wrong (or whatever the reason) and not behaving as it should. When that happens you get differences in exposure in a shot.

If this happens to all your shots, there's no doubt you should send it in.

It's strange there's this mismatch too. That should not be possible since the curtains only block the incoming light. The image on the sensor should not be affected like that.

It almost makes me wonder if your sensor is being moved during the exposure.

I opened it in photoshop and the strange thing is that the small strip to the left of the shot fits perfectly to the opposite side.

That makes me wonder if instead of a hardware issue, this is some software problem.

I agree that it looks like a shutter issue, but just for kicks you could try a different memory card to see if it is some sort of corrupted file problem.

Anyway, Nikon will sort it out when you send it in. Welcome, and sorry about this problem!

I first assumed it to be a shutter issue but a row of two pixels of the one side glued to the other is simply impossible to be caused by a hardware failure. Any movement of the sensor should result in massive blur. What happens here isn't possible hardware-wise.

If you check the shot on the LCD, does it look ok there or is it also messed up?

If it's normal there, this is a software problem during transfer or upon load in the editor. If it is affected on LCD, the problem is the cam's write-down or the card. Try first using another card. You can also install the latest D750 firmware and see if that maybe solves it.

The odds are very low that you'd have an issue with the shutter curtain AND a software issue at the same time.

I am having this same issue, except it is worse than what has been shown on this thread. The first time it happened was when I was copying from the SD to my computer.....the bottom 2/3 of a certain picture was totally gone, with a blank gray color. I deleted the picture thinking nothing of it, before I read this thread. I can't remember if I was scrolling through the pictures on the SD card, or if this happened after I had copied them to the computer, or if it was RAW or jpdg (I have one card for jpeg, the other for RAW).

Yesterday, while scrolling through pictures in camera, some of the pictures were 'bleeding' into eachother next in order, like overlapping. I only had about 25 pictures on the card, so I scolled through it completely and the next time through the problem was gone.

But, now it is doing it again in camera with the same pix. After download to the computer, this is what I am getting. You can see what the thumbnail looks like at the top which is correct, with the corrupted photo at the bottom when I enlarge it:

This is only happening on the jpeg SD/file, the RAW are ok. I have slot one RAW, slot two jpeg. Also, when I was taking the pic of the computer to post this, other jpegs were doing something similar or worse, like half the screen was deleted with a pink color similar to the original gray occurrence, but when I got out of the file and went back in, they were OK. Also, LR will not recognize this particular corrupted jpeg. This is irritating.

I will switch the SD cards around today and try different settings on the slot designation and report back.

Update 1: Switched the cards, same setup. Glitchy 32gb card that was jpeg slot 2 now in slot 1 RAW, 64 gb in slot 2 for jpeg. Took about 50 pix, no corruption on any files RAW or jpeg.

And to avoid corrupted cards, if that's the case, are you in camera reformatting the card. Shoot, offload photos, reformat card in camera. I have personally seen and had to recover photos for friends when they weren't following this procedure and the cards get corrupted.

No, I have never reformatted cards every time I remove/put them back in the camera, on any camera I have owned. That would be a canon crop I had in 2009, D3200, D7100, various point and shoots, and now this D750. This D750 is the only time this has happened. I will start doing this, though.

And every single time can be on the "paranoid" side, but Wendy on here and another Nikon photographer that had visited here both had it happen at of course the worst time. The thing is, once your in the habit you don't even think about it. Many of us limit ourselves to smaller size cards (16 GB myself) and change them out. That way if the card goes belly up its not 32 or 64 gb lost.

Hope this all helps and please report back once you can make a final decision on what happened.

For any trouble shooting, you must use a method. In your case, I would start by:
1-looking at the jpeg picture in camera. Does the picture have this problem when viewed in camera. If not, then the problem is either the card reader (try connecting the camera to the computer to see if the problem is still there)
2- if the problem shows when you view the file on the camera's lcd, then the problem is within the camera conversion program OR a bad sd card. You could try a different card that was formatted in camera. If the problem subsists, try a camera reset and if it doesn't cure the problem, it's time to call Nikon warranty service.
Hope you solve your problem without having to send the camera back to Nikon.

Yes, I need to get in the habit or reformatting. I plan to set my other slot as duplicate as well for the time being and see what happens. I will experiment some more and post back if any other issues.

What is frustrating is that it is intermittent. Recall on my other post, when I went back to recheck the corrupted photos they were ok, this is on my computer. I just them checked again, and one of the pix that had 'returned' to normal is corrupted again differently. Instead of pink blank taking up most of the photo, it is now white. And, as I noted the review in camera showed bleeding from one photo to the next, that I cannot duplicate in computer. It isn't consistent and even the corruption varies when viewed from different media at different times. Maybe I need to start drinking early today.

1) Note in my post you quoted, I detail out what it looked like when reviewed in camera. Some of the photos were bleeding or overlapping into the next ones in sequence. I scrolled through the photos again, in camera, and there was no corruption. When I downloaded those same photos to my computer, more but different corruption was the result.

I am thinking and hoping it is a bad card, but per my other posts the corruption is inconsistent and changes when viewed at different times.

I would start with two different cards, camera reset, and format the cards in camera. Maybe even access a different computer so the whole setup is fresh... And a drink too!

reading your post, its exactly what I went through after shooting a few weddings. I always have at elast 2 memeory card readers around. I have two of the same transcend usb 3.0 readers. opened the new one I had for a backup and the images were just fine.

you have another memroy card reader? had the same thing. in camera alls good, on the pc it looks different and even each time the corrupted images "corruptness" looked different
