Oryctes nasicornis, European rhinoceros beetle, 32 mm
As I've mentioned in a couple of recent posts I've been playing around with an experimental solution for wide angle macro shooting. I promised I would elaborate on it, so here goes!
I recently posted a more detailed version of this on my Swedish blog: makrofokus.se/blogg/2016/9/22/diy-makro-fisheye.html The English bot-translation is actually quite good.
Otherwise, please have a look the first comment below for a summarized description, photos of the gear and more sample photos!
This image is stacked from four exposures in Zerene Stacker but it's not really focus stacked but aperture stacked (explanation below!).
