The Exif tag for resolution has nothing to do with the pixel dimensions of the image, nor with the size of the file. The file size reduction from MB to KB can be either or both of increased compression (lower quality selected) or resampling to a smaller pixel dimension (say from 24MP at 6000x4000 down to only 800x600).

Thomas, I'd contact the folks requesting this resolution and seek clarification.

Hi all, the better half asked me to take some shots of her quilt to be sent in for a contest. One of the requirements were that the pictures submitted be 1200 dpi. I am shooting with a Nikon D750 and checked the manual and cannot find where there is a setting for this, they come out as 300dpi. Can someone please enlighten me why they might require this 1200dpi and how to achieve it? Is there a camera setting I am missing or is this done in post?

Hi again, I got some lore information from the better half and it looks like they are talking printing. It seems odd as they request the pictures to be in jpg format. Here is what they sent her, not sure if the formatting will work here so I'll try to attach a PDF too. I think I'll just stick to birds and landscapes.
