Question about enlarging digital photographs.

[Silent3]

9. The quality of the result isn't guaranteed, but of course Photoshop can enlarge pictures.

Any online source that told you that you can't use Photoshop to enlarge pictures wasn't a very good source.

Whether the image looks sharp or fuzzy when you enlarge it is going to be the most common issue, not whether it looks pixelated. You'd either have to start with a very low resolution original, or deliberately go out of your way to use a non-smoothing scaling technique, to see much pixelation.

The important questions here are:

1) What is the original image resolution, in pixel width and pixel height. Don't worry about the original ppi -- what really matters is how many source pixels you have.

2) The distance you'll normally be viewing the image at.
