In this article, English photographer Barry Webb explains that due to the size of the subject, "one picture would not do them justice, you can get virtually nothing in focus".

He describes how he uses a technique called focus bracketing, where dozens of photos are taken.

"You take multiple pictures, sometimes over 100 and it takes tiny little slithers of focus, and then you put all those into software, and that creates your final image."

@AkaSci
The later Canon 7 series cameras* will do it in camera.
Occasionally useful.

* I use them for runners and triathletes, they are also optimised for wildlife, and are, like most equipment these recent several quinquennia very good cameras.

@Photo55
Do you mean that the later Canon 7 series cameras can be programmed to take multiple images at slightly different focus settings and then stack/stitch them together into a beautiful composite image?
@AkaSci
I think Canon would say that beauty isn't their department, but yes, focus stacking and combining they do. I think it only arrived in the R7 - I have the earlier ones as well.
