Exposure Problems on a D750

How about you take a series photos with out changing anything between shots and see if the images remain constant.

I am going to shoot some photos using a 50mm 2.8 prime lens & see if there is any change.
I might put the Nikon 18-300 on my 7100 & compare the results.
I will post the results later today, time providing. Bill

Can you post the Exif (Metadata) data from the photos? You can view the metadata in any of Nikon's software programs like ViewNX 2, NX-D, and other software programs like Photoshop. The Exif data seems to be stripped out of the photos you posted. I tried to extract the data from a variety of online Exif viewers. Maybe other UHH members were able to.

I am glad to know that you did not sent your camera to Adorama. Almost everybody thinks that your problem with this camera is operator's fault or firmware. BTW what version of firmware do you have? It is very interesting to solve your problem. Good luck.

I used Photoshop CC to see his Exif data without any problem.

If you "download" and save the images you should be able to access the data either by checking the image properties or by loading them into Photoshop.

What did the EXIF data show? Were there any clues that could answer the problem for yhe OP?

EXIF data shows that after every shot camera changes exposure metering mode.

The only changes were the B-5 or 6 fine tuning exposure & they were reset many time just to try to get equal results.
All my other Nikons remain at the same settings on all shots.
Most of them are matrix +3, center weight +2 & spot +1 or 0.
This D750 is ok for some shots, but you can bet i am not going to reset them for each occasion.
My D800 had to be re calibrated & the D7000 also by Nikon.
After that they were great. The D7100 just needed the B-5 adjustment.

I would email Nikon support. I've emailed them many times with questions. They might know if the camera automatically changing metering modes has been a problem with other D750's
Were you fine tuning the metering modes to try to get equal results from the three modes? They should give different results. You just need to know which mode will work best for the particular scene..

I can't believe that 2 D750's automatically changed metering modes, I strongly can't believe that if there were 2 D750 exhibiting the same strange behavior that both of them went to the same customer. The odds of that happening have to be astronomical. And even though I do not have a D750 I can't believe that any camera, let alone the 750 would do this without operator input. I think the user here is under the impression that he should be getting the same results (image wise)no matter which metering mode he is using and has been attempting to 'fine tune' the different modes to give him that result and since he can't get there,that is what his complaint is.

I don't know if this will help, but I just got the D750 and did a high key session. I was on manual and metered the scene. The LCD looked great but the downloads were over exposed. The low key looked fine. I went to menu and at the "set picture control" line, I change the setting from SD to NL. I just re-shot the same set up and the download was much better than before. Good Luck

Took the 28-300 from the D750 & shot some photos with it mounted on the D7100.
Images were perfect. So can't blame the Nikon 28-300 lens.
I will call Nikon monday & check with their tech dept.
Yes it does have the latest firmware.

Please tell us what Nikon suggests and could it solve your issue.

This is the OP's third camera with a exposure problem. It all started when he gave his wife his D7000 and she started out shooting him.
When his first D750 had a problem I suggested asking his wife for advise, it looks like he hasn't done so.

This exercise points out exactly what the problem is. With the black truck in the centre of the frame the camera is doing exactly what you would expect: with pattern metering it gives a good exposure; with centre weighted the black truck influences exposure more and the image is under exposed; with spot metering the image is exposed to make the truck middle grey. The question is: Is the operator changing the metering mode or is the camera doing it without operator input?
