There are people saying 12mp is enough 10 years ago.......... which is correct. It is enough. But we can have better and better is better.

But, if you're printing 12"x18" or smaller, "better" is invisible. ...

Not true. If you apply processing (to reduce noise, lift shadows, enhance detail etc.) prior to downscaling for print, the difference will be palpable, even at 12"x18" or smaller.

It's not a processing issue.

The difference will be visible no matter what the shadow lifting. It take 6500 pixels for an 18 inch wide print at 360 ppi

Yes, but your eyes likely cannot resolve 360ppi. That 360ppi number is widely cited, but it is randomly selected and bears little relation to the average person's eyesight. Furthermore, it assumes that you view prints with your nose on the paper, which nobody but pixel-peeping photo tech enthusiasts does.

I find almost no visible difference, even at a viewing distance of 12", between 200dpi and 300ppi in a print that's been appropriately sharpened for the specific media and output size. Try it. You may first have to learn how to appropriately sharpen for print. You can start by trying Pixel Genius' now-free PhotoKit Sharpener.

( a few more than you can get with a 24 MP 3:2 camera). A 12 MP camera will get you about 240 ppi. That's good enough for most things, but not for all uses. If you print on matte paper, there's probably no visible difference.

Some folks will do just fine with 12 MP. Others

who examine prints with a 4x loupe

will want more.
