Can you enlarge a photograph from the original photograph?

Answer:
Yes, but the detail is not any better than the original photo. In fact it get a little softer.

If the picture is worth the effort and expense to you, have it copied with a large format camera (4x5 or bigger). The result will surpass anything you will get by any other means. You will need the services of a professional lab unless you know someone with such a camera. I once had a poster (about 24x36) made from a 5x7 and the result was amazing.
