Flower Fireworks – Happy New Year!


Most people can look back over the years and identify a time and place at which their lives changed significantly. Whether by accident or design, these are the moments when, because of a readiness within us and collaboration with events occurring around us, we are forced to seriously reappraise ourselves and the conditions under which we live and to make certain choices that will affect the rest of our lives.   – Frederick F. Flack

Thank you all who have visited my blog this past year. Especially, I wish to thank those people who are following this blog and who have provided comments on my posts. I wish for you all, health and happiness. Happy New Year! I have found inspiration in the posts of many of you. 

I cannot remember the last year that I made resolutions. This year, for whatever reason, I have decided that resolutions are appropriate.

Here are my (daily) resolutions:

Learn five things that are totally new to me:

  • a fact or piece of information (ie the pygmy right whale belongs to a species that was thought to have been extinct for millions of years. Not very practical info, but I enjoy being amazed. Science has not even figured out all the data about the animals that are here.)
  • a picture of something that I have never before seen, or at least that I have never seen depicted in that style (Yesterday’s find was Guy Tal’s marvelous landscapes that he has processed as paintings (http://guytal.com/gtp/gallery/index.jsp).
  • listen to a song that I have not heard before (thank you Pandora)
  • do something that extends an ability that I already have (like learning a new technique of photo processing)
  • do something in a way that is not my usual way (such as… I don’t know. This category is going to take some effort)

Give an unexpected gift to someone

Show, through my actions, that I love someone.

Become conscious of at least 20 things for which I am thankful.

Recommit, through actions, to my values and priorities.

Post more often on my blog, not worrying about proper grammar or punctuation.

The photo at the top of this page is a large chrysanthemum, each bloom of which is at least 4-6 inches in diameter. Usually close up photographs have a shallow depth of focus, that is, only a portion of the subject is in focus. This photo is almost entirely in sharp focus, because of using a technique called focus stacking. Multiple images are captured that are exactly the same except for the area in sharp focus. In this case, 41 separate photos were taken, beginning at the closest point of the flowers to the lens and working toward the back of the flowers with the focal plane of each photo being 2 mm deeper than the last. Then all the images were processed with Helicon Focus software (from http://www.heliconsoft.com/heliconfocus.html), which does an unbelievable job. (I highly recommend it both for close up/macro work, and for landscapes.) If you are interested in more information on focus stacking, please check out my first two posts of this blog.

Again, I wish you all a Happy New Year!

I welcome comments and criticisms (mostly comments).

Expanded Depth of Field Photography: Introduction

“The fact that I can plant a seed and it becomes a flower, share a bit of knowledge and it becomes another’s, smile at someone and receive a smile in return, are to me continual spiritual exercises.” -Leo Buscaglia

The technique of expanded depth of field, also called focus stacking, produces objects and scenes  that are totally in focus from front to back. Generally in photography, single images of close objects render only a portion of the subject in focus. Sometimes this is exactly what is needed. It draws a person’s attention to that limited area. At other times, this limited depth of field of a single image is distracting and  limits the amount of visual information available, compared to what is actually seen by a person at that time.

Our eyes scan objects and scenes, focusing very quickly on many different areas. This gives us a perception that everything is in focus simultaneously. The technique of expanded depth of field also produces an image with the object or scene totally in focus. For this reason, the resultant composite image appears more realistic than any single image can. This also allows people to connect more fully with the subjects, to feel an emotional connection. In this way, the expanded depth of field technique can become a valuable element of photographic art. Effective photography obviously requires more than just technique. However, this  is an aspect of digital photography that is superior to film, in fact , impossible with film.

This is the first of a series  of blog post on this expanded depth of field photography, also called focus image stacking or simply image stacking. This is a technique with which multiple, nearly identical, images are taken of the same subject. The only variable between frames is the depth of field/focus. Importantly, the depth of field must overlap between images for successful results. Then via software, the sharply focused areas of each frame are incorporated into a composite image which is entirely in focus.

Although initially intimidating, this technique can be enjoyed by anyone with the proper equipment and the willingness to take their images with great care.

I plan a series of blogs regarding this technique. My target audience is amateur and professional photographers who are just beginning to use this technique or who have had difficulty getting consistently good results.

I am not an expert; however I have had good success producing dramatic images with this technique. On a typical day I shoot 2-4 sets of images of close up or macro subjects, usually with 35 – 45 images per set. Most of my work, and knowledge about this is close up subjects, although I do some macro work.  To be exact, macro technique requires that the image on the sensor or film be at least as large as the subject itself. For example, a 1/2 inch bee would need to make an image on the sensor or film of at least ½ inch in length. If its image is smaller on the sensor, it is technically a close up image, rather than a true macro image. However, for the subjects that I will be covering, the techniques are essentially the same.

My next post will be an overview/outline of this technique. It will be a “Table of Contents” for my remaining posts in this series. Hopefully I can help other people to get more satisfying results and improve my own technique simultaneously. I invite comments & suggestions.
