Did you try downloading with a card reader and then into another folder from the camera? Which program are you using to view your jpegs?
Glitchy Images From My D750
- Thread starter faberoptic
- Start date
To summarize for everybody and to add more detail:
1) Some of the pix look corrupted when viewing in camera, but after scrolling through them they clear up. Some of these pix are different than the ones corrupted when viewed on the computer.
2) I download using the slot for SD card in my laptop. I have had this laptop for a year, probably downloaded 5000+ photos with no issue.
3) I have been viewing them with Windows viewer, or whatever the default viewer is in Windows. I usually do this and then only import the RAWs I want into LR. I shoot jpegs to mail out or whatever without having to go into a RAW editor.
4) The corruption when viewed on the computer is different than corruption viewed in the camera. The camera made the pix overlap, the computer either blanks out part of the picture or makes them look like the pic I posted earlier.
5) The corrupted files will not open in LR. Elements 12 will open them but warns they are 'corrupted', and then they open and look just like they did on Windows viewer with the same corruption.
6) The RAW files in the other slot with the other SD card were not corrupted. So, as of now this is either a jpeg issue with the camera, or that particular SD card is corrupted.
6) I have reformatted the same cards and switched them, now slot 1 RAW with the card that had the corrupted jpegs previously in slot 2, slot 2 now has the card previously used in slot 1 for RAW.
7) Tested this out and no problems with either card, either in the camera or after download using the same SD card slot in my laptop.
I will continue to test using various setups and post back.

did you try a different card reader? till you havent, you cant rule it out.
Did you try a different card? Did you try to shoot both raw and jpegs on the same card (same slot)? I suspect a card problem since even the camera has problem with it. But on the other hand, if the raw files are all OK...
When did this problem start? Is it just since you've started using the D750? Could you find another camera to try your cards with?
I don't think we can do much for you. You'll have to try all combinations to find which link is broken.
You should check if the pictures look good in cam until you zoom in on a shot. I don't know if the cam displays the thumbnail version as first view and only when hitting the zoom, uses the larger JPEG. If that's the case, when scrolling you see the thumbnails which could be correct but no guarantee for how the actual shot looks like if corruption occurs.
The same can happen in your windows viewers. There too you see the thumbnail version and after opening the shot it is possible it adjusts the thumbnail version to match the corrupted file. But since a viewer does not overwrite metadata, the moment the cache is dumped, it reverts back to the original thumbnail.
If you don't mind, upload a (corrupted) original JPEG here as shot by the cam without adjusting it in any editor. That way I could check the metadata and see how the thumbnail looks.

Yes, the thumbnail is normal, only when it is opened does it do this. The files are too large for the forum, PM sent.

resize the files so you can post them here....hope that helps.
I checked the metadata of a full you sent me and everything seems to be ok. The preview that is added to that metadata is fine too, as you can see here. The full shot had only the top 15-20% correct and all the rest was black.
As far as I know the metadata file & preview JPEG are created before the full version so theoretically it is still possible something goes wrong during the write of the full in cam but I consider that unlikely. I'd bet on the card or the reader.
Here's the full resized.
All what is white is corrupted info. My Mac could load the file but GIMP and RT would not even accept it.

I have confirmed with another "pro" user of the d750 that there are exposure differences even when shooting in manual. I think he said he experienced it with the d800/810 as well... For example when shooting a "Brenizer stitch / Bokeh panorama" You take many pictures in manual mode and manual focus and stitch them all together. it is really weird.....everything should look the same. I think part of the problem is the vignetting, but even with removal it's sometimes impossible to get perfectly matching exposure.
Are you sure the editor isn't to blame for minor exposure differences? I can imagine if any auto-mode is used there are exposure differences, or even when using ISO but at native ISO in full manual I can't image how there could be differences. I have to try that tomorrow.
I'd check the metadata of the shot first. Mike posted two identical shots a while ago that had a noticeable exposure difference even when all settings were identical. When inspecting the metadata, it turned out Adobe applied a different exposure correction for both.
I'm going to shoot some test shots tomorrow since I have a hard time imagining what the cause could be. Basically only aperture, shutter and ISO affect exposure in manual and to have differences, one of those three needs wiggle room. Aperture should be impossible and shutter should be exact too. I can imagine ISO could have a minor effect since differences in photon counts are magnified by ISO but even those should be hardly visible.
The only other thing could be the cam converting the values differently between shots but that should show in every shot we take. To test that all which is required is some plain colored subject without texture, light that correctly and shoot several shots. If the cam has wiggle room in its conversion, the plain color should show that by having differently exposed areas.
I'd personally put money on the editor.

Well, I don't apply changes upon import. When I shoot pictures to stitch together, I don't ever change manual settings or apply different settings on them. Like I said, it's possible that vignette correction is at least a factor. There are other people complaining about this simiilar issue on the nikon pro discussion group on facebook. I would LOVE to say it's user error because I have experienced the issue myself, but it's not appearing so

If you link the full shots somewhere so the metadata can be read it'll directly show if it is cam-error, editor-error or user-error.
It has been raining all day so I couldn't check what mine does. I'm quite curious.
I can report I've used my camera sparingly the last week, but have had no issues since I reformatted. I have changed my setting for slot 2 to be duplicate. I plan to go to Galveston in the morning to shoot the sunrise and maybe some street stuff so I will know better after that.
I really like the flip screen, more than I imagined. I took the pix of my cat with the camera on the deck, screen flipped up so I could frame it properly. I was using my 60 macro prime....yes I have one of those useless non tele's J-see.
The flip screen is great. At first I had a "I don't need all that crap" attitude. However when you can hold the cam low and still see what you do and remember that before you had to lay on your belly in the mud, you really start to appreciate that "crap".

Yes, I was the same way. I do have neck problems so I thought I would use it when on tripod when I bend over to compose, but I use it much more. Here is another one, at a river near my sister's place over by Lost Maples State Park in Texas, this is the Sabinal River. I almost dunked my camera by putting it too close to the water, not paying attention with the screen flipped up. I partially submerged the end of the lens before I noticed.

I never thought I'd use the articulating screen nearly as much as I actually do. Now, though, I wouldn't give it up; it's *amazingly* useful and the build is a lot more solid than what I was expecting.

Hi everyone. I am user of Nikon D 750 and after few months of using it I experienced problems with coloured patches and lines on my photos in high contrasted places( lines on the sky and patches on clear surfaces like sky and water. It's very annoying. I thought it's my Tokina 16-28 f 2.8 lens but problem occurs on Sigma 24-70 too. I checked my serial number and it's says that my camera is affected by flaring but I never experienced flaring as it was described. Could it be related to my issue? Please help.
