Photography Techniques — Focus Stacking.

I have been using Helicon Focus to make composite focus stacked images for several years. It is great for doing macro images with much more depth of field than can be done with single images. I spent the day doing some focus stacked images on some small cactus flowers. The images were taken with a Nikon Df camera and 105 mm f/2.8 VR macro lens. The camera was set up on a tripod on with a linear tracking head. The first set was with 13 images, in 5 mm intervals — which wasn’t enough. The second set was 24 images over 9 cm. That one looked better. I then added a TCE-3 III teleconverter (converting the focal length to 210 mm). The camera was set closer and did 33 images over 9 cm. The slide-show below shows all of the images. It includes one image from each set at a single distance. To see the individual images check here

My interests include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.
