I have a number of pictures where I wish to enlarge certain areas into large photos, without losing integrity. I am told that one can use CS2 or a plugin to maximise the pixles without losing integrity of the photo. Can someone help me?
Thank you

No. This question comes up continuously in this group, and the answer is always the same. It can’t be done.

You’re screwed. What you are asking is not possible.

You’re told wrong.

Nothing–no program, no plugin, no technique, no algorithm, nothing–can enlarge a raster (pixel) image without reducing its quality; absolutely nothing can enlarge an image and create detail that does not exist in the original.

If you want to expand an image and preserve high quality, here is what you must do:

Step 1: Click on the image in Windows Explorer.

Step 2: Drag it to the Recycle Bin.

Step 3: Empty the Recycle Bin.

Step 4: Re-scan or re-create the image at the proper resolution to begin with.

Sorry…

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.

< http://www.benvista.com/main/skin1/images/products/examples/ photozoompro/enlarge400.jpg> will help to understand that there can be many ways to fill-in the blanks, all equally valid, but probably unlike the real scene.

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 <http://www.ddisoftware.com/qimage/>. It can also print to a file for other use. It produces superior print quality.

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.

Using CS2 Photoshop.
Resize-= use bicubic smoother
Enter an increase in %age at 120
Do this up to five times.
Something I have learned from reading "books."

Record all the steps Rumpledickskin described the first time with "Actions" and do the other (4 or as many as you want) times by "playing" the Action again.
