Bi-focal Images – ICT #1

Since I have published my “Nine Basic Rules of Motion Photography” quite a few people have asked me to share a few more of my image creation techniques.

So today I will be starting a new series of  message with “Image Creation Techniques” or short ICTs. From time to time I will publish blog messages explaining some of the ways I create my images.

Please feel free to make comments or ask any questions (either as comments on the blog message or as emails to

Bi-focal images (ICT #1)

Often it is not possible to use small aperture to create an image with “deep” depth of field.

Here are two examples. One a is a snake picture and one is a scenic shot. In both cases I had to work with fully open aperture, because of the light available and the fact that the use of a tripod was not possible.

In case of the snake picture I wanted both eyes and nose in focus. So I shot multiple images
while slowly changing the focus from eyes to nose. I then used my editing tool (I use Corel Paintshop Pro) to merge two of the pictures and create the final image.

In the case of “the tree in the lake” I held the camera about 2 inches (~5 centimeters) above the water and shot one image with focus on the ripples up front and one image with focus on the tree in the background. Then I merged the images (stiched at the horizon). The results in an image with an interesting bi-focal effect.
