Make sure you view it at 100%.
It's a 100% crop of a focus stack of a butterfly's wings. I think it was a swallowtail. I found it dead in my garage.
I shot with my D600 and Tamron 90 mm f/2.8 1:1 macro lens plus a full set of Kenko tubes. The magnification should be a little less than 2:1.
Lit with an Elenchrom Style 300 flash through a too-large softbox (the only size I have)
I shot a stack of about 16 images, using a focus rail to move the camera in tiny increments between shots. You do get better results using rails for a couple of reasons. First the entire image can be shot at closest focus. Second, the lens optics don't change between shots.
I find the level of detail you can get mind-boggling. The scales on the butterfly's wings look like woven fabric.
