Printing from a small .jpg

[kismet72]

Hello,

A friend accidentally shot a studio newborn session in the small .jpg setting on her Canon 5D Mark III. This results in a .jpg file that is 5.5M and 2880x1920. So, first off, she's pissed because it's not RAW, but she did pretty well in camera and the photos are well focused and color is decent.  Second, she is concerned she won't be able to print a large canvas, like 30X40, if the client wants one. It is my understanding that she should still be able to print to some decent sizes. When opening the photo in photoshop and checking the image size, on inches it says 9.6x6.4. How do you go about printing larger than that size? Do you  create a new file in photoshop at the size you want, say 24x30, and then use the place embedded option?

help would be much appreciated.

The colour doesn't matter a bit, but the focus matters a LOT.  They'll need to be razor sharp.  And they'll need NO cropping whatsoever.

She's right.

At what resolution?  The resolution is important.

No, that's complete nonsense.

Resolution is 300ppi. So, if everything is sharp and there is no cropping how big could she go?

Exactly as per the graph in the link I gave you.

8x12 at most (print).  Or 16x24 on canvas.
