Prepping 2K Motion Picture Frames For 8x10 prints?

[quadra605]

I recently had some 8mm stop-motion films I shot in the 1980s scanned to 2K and would like to make 8x10 prints of some of the scenes (and possibly use several in a book a colleague of mine is writing).

FCPX allows me to save selected frames at the resolution they were scanned, but opening those same frames in Photoshop and choosing "Image Size" shows me the pixel dimensions are 2048x1484, and the document size is 20"x28" with a resolution of 72 pixels per inch.

Now, my understanding is that for printing photos, a target of 300 dpi is required/desirable. If so, what is the solution? Or will 72 ppi work fine?

I read one solution that suggested exporting your image to a PDF file, then exporting that PDF back to an image and choosing 300 dpi resolution from the ensuing menu.

Any advice/suggestions are appreciated!

That's a rule of thumb, but the best solution is just to print it and see how it comes out. Do you have a printer at home that can print 8.5x11 or A4? If you print an 8x10 onto that you'll get an idea of resolution even if the quality isn't as good. I've had prints well below 300 that come out good, and some that are above 300 that just weren't sharp enough (despite technically having the resolution)

You can take the image into photoshop and change the resolution to 300. It will automatically change the inches and then you can see what size it will print.

or try a converter if you don’t have photoshop.

The inches and dpi is just a ratio. The dpi is really for screens not printing.
