There was hardly a breeze yesterday evening, so I attempted my most ambitious focus stack to date. With more than 100 shots of the bottom part of a fern, I had to skip every other shot in order to lessen the amount of computer processing that would be required.
Here is a 52-shot stack:
I didn't time how long it took for each processing step, but it took PhotoShop something on the order of ten minutes to align the shots and another ten minutes to create the focus stack. The resulting file was huge -- approximately 5.3 GB. Thank goodness that the primary Adobe swap file resided on the solid state drive!
A Growing Ferns from Spores web page helps to define some of the plant anatomy. Each large, dark pod is called a sorus. The individual spores are packed inside each sorus. The covering of the sorus is called the indusium.
Close-up, they look like little spore sliders.
