I want to blow up some old prints of my children. They were taken 15 years ago on a Nikon camera. I want to blow them up to 30x40" but the photo lab gives me the warning that the resolution is not high enough for a good quality print.
So I looked into maybe ordering the "blow up 3" app, which also means I need to get a subscription to Photoshop. I would be okay with all this investment if I were sure that it would result in good quality blow ups, but I'm not sure. Does anyone have any advice for me? I'm not a photographer at all, but I've taken some awesome photos in my past!
