10 M pixel JPG image says 72 p/inch

Just a question...
I got this 2592x3888 pixel image shot in JPG
If I use CS4 and image size it says that the resolution is 72
I just notice this since I was shooting some water drops!
I started with doing RAW but it was too slow so I switched to JPG for more burst.
I very rarely do JPG so I had expected the resolution to say 300 and not 72
But the correct pixel count is correct so it shouldn't matter on the output result.
I am just curious why it doesn't say 300?
When I convert from RAW to JPG it comes out as 300.

DPI is *only* relevant when it comes to printing. The DPI setting embedded in an image tells the printer what to print at.

Your raw converter is assigning the 300 number. When you shoot JPEG you aren't using the raw converter, of course.

Where does the 72 come from? It's the official specified default in the EXIF standard. If your camera doesn't fill in that field in the EXIF then 72 is assigned.

So it means nothing at all.

Thank you. I tried to search for the answer but everything else came up

As you can see in the quote, I didn't ask for what you answered on. But rather why Photoshop comes up with 72 instead of 300. Thank you anyway
