That is not STRICTLY speaking true.
Photoshop has at least 3 upsampling algorithms which produce meaningful results with good resolution. By the time you got to CS6, options were up to 5 or 6.

I've made 24"x36" prints from 8.3 meg resolution sensors. First rule? START with either a Camera Raw or the highest level of JPG your camera supports. My former go-to camera, a Canon EOS 1d mkII had at least 10 choices of JPG compression (think visual MP3) and RAW. You also had choice of sRGG or ADOBE RGB color space.

The limits include not being much help with MOTION blur or out of FOCUS blur. But when starting with the best possible file, you can get surprising results.

I'll accept ONE FILE for modification and let YOU be the judge. But it better be the BEST file you've got, at least technically.

Don't forget, all you need for a good print is 300dpi. Above that does NO good.

In the shot I refer to, above, you were able to see the subject had a piece of green stuff in her teeth.

I also made and used my own copy stand. Using a Macro Lens, I could make copies easily indistinguishible from the original or in some cases of faded originals, BETTER.
