    Underexposure

    Underexposure
    I know underexposure is talked about regularly with the D750, so please bear with me...

    I recently got a pre-loved D750 after a few years enjoying the D7200.

    I photograph a lot of aircraft, and I'm fortunate to have a lot of cloudless days.

    Photographing jets against a strong blue sky, every frame is underexposed. Here's an example:

    Underexposure-dsc_3519_00001qf-a330_01.jpg

    This JPG is a RAW file that's gone straight through Capture NX-D with no adjustments other than 'vivid' picture control set on the camera. Matrix metering and ADL off.

    I did not have this issue with the D7200. Is the large area of blue sky, or the bright white of the fuselage, throwing the metering in some way?

    The answer to your question is, "Yes... Matrix metering averages the entire scene"...

    Do I need to try centre-weighted?

    You can. Just realize that shooting sky images like airplanes means, depending on which direction and time of day, exposure can change relatively quickly... Being able to assess your conditions, and then adjusting for those conditions is your challenge. There is NO magic bullet.

    I always struggled with matrix metering and instead use center weighted metering most of the time (except when I switch to spot metering on rare occasions). No matter whether I'm photographing a bird or a plane, I always override my EV and dial in +0.7. The sky is extremely bright and will heavily influence metering.

    Honestly I'm surprised you photographed planes with the D7200 just by using matrix metering and not needing to increase your exposure. It just didn't work for me. You can always keep using matrix metering but try and increase your exposure with the +/- button and see if you will get more consistent exposures.

    One more thought...the D7200 is a DX sensor. Perhaps with planes being closer in the DX viewfinder, there might not have been as much sky in those images to influence its sensor?

    It's quite confounding. The image below is from the D7200, with matrix metering, and again straight out of Capture NX-D. The only difference is that picture control was set to 'standard'.

    In this case, noticeably (though not seriously) overexposed. A different time of day (and a different time of year) may have given me a different colour sky, too.

    Just some thought. First to me at a little after five this time of the year the image looks a little yellow. Second if you were using the same lens on the d7200 it would show less vignetting if any and there for brighter.

    The d750 shot looks like I would expect. I can't explain the d7200 shot. Anyway, I just wanted to share something I have set up. I mostly use matrix metering but I assigned my fn and pv buttons to center and spot metering so I can apply them instantly as needed. Sure I could quickly change modes in the normal way, but I will forget to set it back to matrix almost every time.
    I must have a really good camera.

    The A330 shot was taken late in the afternoon with the sun about to set behind me.

    I really like both these cameras but what's surprised me is how different the images are from each.

    Could very well represent what you saw. Didn't check sunset time and don't what part of the world you are in.
