I have a number of pictures where I wish to enlarge certain areas into
large photos, without losing integrity.
This is a dilemma that is best solved by either shooting or scanning the image in as large a size as possible. Any type of interpolation is mere guessing the missing pixels.

That being said, there are a couple of programs that are better at guessing than others. So if it isn’t possible to obtain a better quality image to start with, they could help in making a reasonable guess, which is better than no guess at all. However, it’s second choice, nothing beats the real thing.
There are two programs I can recommend. One is a stand-alone printing application, after all printing is the most common need to interpolate, and that is Qimage <

The other is also a stand-alone application, called PhotoZoom, but it also has a Photoshop export module:

There are several other programs that claim to do a similar job, but IMHO their results look rather artificial with unnaturally sharp edges and otherwise relatively featureless, almost painterly areas.
