How large can a 7.2 megapixel photo be printed before it loses the quality of a professional photograph?

Question by Sisyphus: How large can a 7.2 megapixel photo be printed before it loses the quality of a professional photograph?
Some of my 7.2 megapixel photos seem to be of a professional standard (thanks to photoshop). Rather than print them as normal photos I plan to print them as my own photography book/portfolio of about A3 size. How large can 7.2MP be before they lose quality? What’s the minimum MP needed for quality A3 size photos?

Answer by spunky monkey
I have a 7.2 MP camera and I have blown the picture up to 8 x10 with out losing any quality. I have never tried to go higher.

    In my experience, A3 is about as large as your going to get without noticeable quality variation. Be sure you use ZERO file compression using photoshop. With 7.2 megapixel and printing professionals you can blow photos up to poster size with minimal image disruption. Play with the camera, play with photoshop, play with printing. Learn as you go. Depending on the camera 15 x 20 should be a very comfortable maximum.

    1. pro photogs dont use photoshop. they get it right in the camera
    2. pro photogs dont use 7.2MP point n click cameras
    3. there is no way your point n click camera has taken pro quality pics
    4. you probably have some nice snaps that you are proud of taking.
    5. print size without image degradation depends on lots of things only one of which is megapixels. see the link below for more info.
