I just noticed what may be a problem with my D600. Perhaps someone can shed some light on the issue.

I was editing pictures shot recently and the finished file sizes seemed small. I took some test shots and looked at the unedited Metadata only to discover that the file size of a picture just taken is about 15.7 Mp. The camera should produce a file size of about 24 Mp.
I am shooting RAW and FF. Is my camera going South or am I missing something in Set-up?

Any help is appreciated.

The file size if in megabytes, not megapixels, Your camera's sensor is 24 megapixels. However I would expect your raw files to be bigger than 15.7 mb. Check your output settings.

24Mp <> 24Mb

The file size (megabytes) is dependent on how much "stuff" is in your pics. A mostly blue sky image will be smaller file size than a garden full of colorful flowers.

Exactly.
The more "complicated" the image, the larger the file.

I think I have found my issue, but now I need some education in Output formats.
I use Lightroom to organize my photos. I exported a photo as jpeg and got a file size of 17.9 Mb. I then exported the same picture as .DNG and got a 26.5 Mb file. That tells me there information in the .DNG file that isn't in a jpeg file. There are a few other output formats as well. Now my question becomes what file format should I be using to output my photos for viewing or passing around digitally?

For digital viewing, you should use the minimum size and pixel resolution needed to present your images to the full size of the target display terminal. This post explains in detail and presents screen-print examples from LR to assist and demonstrate: Recommended resizing parameters for digital images

Thank you CHG CANON.
It looks like I was doing things correctly but got confused with Mp and Mb.
Maybe I need a new hobby....or a nap!

The most common format for "passing around" is JPEG.
DNG is Adobe file. Would people have to have Adobe to view it? I've never created a DNG file.
All the images on my web site and Facebook are JPEG.

The universal file is the JPEG. Usually they tend to be smaller files according to their compression.
JPEG files are used for display in the Web and for printing. By the way, sRGB by the same token is the universal color space.
