24 x 30 prints at 300ppi?

[anita1390]

I'm trying to bring in RAW files from a NIKON 7000 (NEF format), which I am able to do, but only at  16.4 x 10.8 at 300ppi.  This is no different then bringing in a JPG  at 16.4 x 10.8 at 300ppi  --- I was hoping the camera's RAW file would be much larger so I can output a 24 x 30 print.

I need the image to be 300ppi at whatever size I want to output, in this case 24" x 30" at 300ppi. What am I missing regarding RAW files, can this print size be done? I suppose I can add pixels but I am really hoping to capture more from a RAW file.

The raw file does not change the file size. The size is determined by your camera.

The file size in the camera is determined by the number of pixels wide by number of pixels high.

The formula is

width in inches x ppi = width in pixels

Therefore knowing any two of those variables will provide the third.

pixels / ppi = inches

Now that you know this, to get a larger print, you can reduce the ppi. Keep in mind the ppi is the number of pixels that are packed into a single inch. Which means it is subjective to how far away the print will be from the eye. The further away the print is the lower the ppi can be and still have a high quality print.

I hope this helps.

And to add to Silk's excellent reply, you can probably get away with less PPI - 200 or even 150 PPI if it's being viewed from a few feet away.
