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.

Bye for now, George Dingwall Invergordon, Scotland http://freespace.virgin.net/george.gdingwall/index.html You could also use a tilt lens or a bellows with tilt. This lets you control the plane of focus so it is possible to have tremendous sharpness depth in a given plane with a lens wide open. To broaden the width of the plane you can stop your lens down to increase the depth of field. this is controlling the plane of focus via the Scheimpflug principal where an image plane and the subject plane meet at a common point. Novoflex is one supplier of a tilt/shift bellows. By doing macro work and combining depth of field with control of the plane of focus you may eliminate any need for software to correct any areas of unsharpness and save time by capturing the desired area in camera. -- To reply no_ HPMarketing Corp. |
