I'm an amateur at Photoshop Elements; within a narrow range of processes, I can improve the appearance of a picture, but there's plenty I don't know how to do as well. And so I ask unto you: can anyone comment on the possibility of increasing the size of a photo without turning it into pixelated hell? Is there some sort of smoothing I can do afterward that will make it print out better? Is there some magic percentage to which I can increase the size without significant drawbacks? It's possible that I could increase the size a moderate amount and then simply add a solid frame/backdrop around the photo that will fill in the rest of the 8.5x11 space. I just really want to use this photo, but I don't want it to look embarrassing.
For example, this site claims that if you repeatedly blow up the picture up by 10%, you will get acceptable results. True? BS?
