(d7500)  I have recently been messing around trying to get a picture shooting in raw and editing in light room.  I noticed that the raw files have around 13.5 mp, which seems a touch low, but when converted to jpeg, I only have 8mp or less, and this is with no cropping.  I looked at some old pics, and they all have between 13 and 19mp.  I checked that the pics were being saved at highest resolution, saving both on lightroom and ps elements.

 

What is going on here?  I tried shooting in jpeg fine, with the same result.

 

Thanks

Rich

Hi Rich, welcome to our forum! That is extremely weird. Are you sure that you're looking at megapixels and not megabytes? Can you let me know the exact pixel dimensions of the images in question? The Nikon D7500 shoots 20 megapixel images, 5568 x 3712 pixels, and those should be the pixel dimensions you see in Lightroom raw files every time.

I just took a nef file to PSE.  raw was 13.6 mp,   2864 x 4304.

converted to jpeg it was 9mp, at 2844 x 4272.

I agree that the numbers should be as you say, but what's going on?

Where are you seeing the 13.6 megapixel and 9 megapixel numbers? The pixel dimensions that you listed work out to 12.3 and 12.1 megapixels respectively.

I have a similar camera, the Nikon D500, which has the same sensor as the D7500. I am wondering if you've got the following option enabled: "Choose Image Area: 1.3x". I never used it but 20/1.3^2 is approximately 12mp so perhaps that is the problem?

The option is in the photo shooting menu for mine...does your D7500 have this option?

Indeed, looks like something like this has been set :

https://imaging.nikon.com/imaging/support/digitutor/d7500/functions/imagearea.html#:~:text=Pictures%20are%20recorded%20using%20a,image%20area%20(DX%20format).

I would add that the difference between 12.3 MP Raw edition and 12.1 MP Jpeg may be due to some distortion correction process applied or maybe an edition crop before export.

Jason, thank you.  that is what happened.  I don't know how, but it did and now I'm back to normal.  Or the camera is.
