Depth of Field In Macro Photography
Hi there,
I been trying to improve my skills in Macro Photography and have always been a little frustrated at the limited depth of field you can achieve when working with a macro lens at a magnification ratio of 1 to 1 or higher. I found a couple of programs that are designed to help you increase the depth of field by combining multiple images, each of which are focused on a different part of the subject, and then makes a single image with an extended depth of field not possible with a single shot. I've uploaded some sample of images I created with these programs to demonstrate what they can do. http://freespace.virgin.net/george.g...ages/test.html The programs are ; Helicon Focus Pro. This is a commercial program and the trial only works for 30 days if you don't buy a registration key. It can be found at; http://www.heliconfocus.com/pages/focus_overview.html CombineZ. This is a freeware program. It can be found at; http://www.hadleyweb.pwp.blueyonder..../combinez5.htm With care these programs seem to able to defy the laws of optics. From my limited experience, Helicon does a better job, but I'm not sure if the difference is worth the cost of the program. I hope some of you might find them interesting.
