! Alan Hadley, U.K.: CombineZ Movie CZM). The purpose of this free program is to increase depth of focus by combining pictures, but each picture should be in focus at a different depth into the scene. The program is especially useful to microscope users (e.g. palynomorphs) and macro photographers. Excellent! CZM is the latest version, it can process movies, take pictures, and has more macro commands but still has all of the functionality of the former CombineZ5. Still available:
CombineZ5. It works with older versions of windows, but is not maintained anymore. See also:

Helicon Soft Ltd., Kharkov, Ukraine: Helicon Focus. This is a shareware program that creates a completely focused image from several partially focused images by combining the focused areas. You can download and use the program for evaluation purposes for 30 days. Helicon Focus is designed for macrophotography, microphotography (fluid inclusions!) and hyperfocal landscape photography to cope with the shallow depth-of-field problem.

ImageJ is a public domain Java image processing program. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.4 or later virtual machine. It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images (including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw"). ImageJ supports "stacks" and standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering. It can calculate area and pixel value statistics of user-defined selections, measure distances and angles and it can create density histograms and line profile plots.
