focus stacking

“When you take a flower in your hand and really look at it, it’s your world for the moment. I want to give that world to someone else. Most people in the city rush around so, they have no time to look at a flower. I want them to see it whether they want to or not.”      Georgia O’Keeffe
In the desert southwest the smallest of flowers dot the landscape at certain times of year. I agree with Georgia that sharing the world that many pass by is a cool thing… These particular flowers can easily go by unnoticed because of tiny size. These flowers are about the size of my thumbnail.

Tiny desert flower bloom
To capture a flower this size takes a little thought and manipulation. This was captured with the Lumix GH4 and 35-100mm 2.8 Vario lens with 26 mm of extension tubes from Neewer Technologies (get two sets they are very inexpensive and you can magnify even more using the technique below). When you have that much extension Depth of Field is extremely shallow. In order to get the buds and the first flower in total focus to share the miniscule detail I added a tripod and the technique of focus stacking. I focused on the bud in the foreground and made an exposure, changed focus to the bud a little further into the image followed by multiple captures across the surface of the flower. These exposures were taken into Adobe Photoshop and blended together using Photo Merge. When this process is used Photoshop will stack the images and blend together the sharpest parts of the image giving an increased DOF.
