Print IQ

I seem to remember reading that a higher MP source file downsized will result in a cleaner, crisper, print than would be present in a smaller source file.
In other words...that 8x10 print would have a better IQ if taken with a 22MP camera as opposed to a 10MP camera.

Anyone have first hand experience with this, and/or, a link where I may have read it?

As fortune would have it Deke explains it quite well here....http://www.lynda.com …Fundamentals/97​713-2.html
Thanks!

Unless a printer cannot accommodate an unusually large image file, there is generally no reason to downsize an image taken on a typical digital camera for printing. Digital photo printers can print at such a high resolution, that most can print upwards of around a 10 megapixel image at full resolution on one square inch of paper. For example, my printer, the PixmaPro 9000 mark II can print 4800*2400 dpi. That equals 11.52 megapixels in one square inch, at full resolution. As a side note, 4800*2400 dpi is nothing special...Canon's $99 iP4920 digital photo printer can print at 9600*2400 dpi, or 23.04 megapixels per inch. So if you own a new 5D Mark III (22.3 mpx), you can print a full resolution image, smaller than 1 square inch on the iP4920, and not lose a single pixel of resolution.

By downsizing your image, you are unnecessarily removing pixels which most modern printers can easily accommodate, removing resolution and hence, detail from your printed images.

I've gotten excellent hi-detail 13x19" prints from 8MP files, so approx 200ppi. It all depends on the quality of your original image!!
