The strawberry has been done by so many people before and I'm just a beginner in the field of ultra-macro and stacking but I thought I'd offer up my near-abstract of a wet strawberry.
I used a KP on a manual (Nisi) macrorail. The Tamron 90mm macro (version 172E) was mounted on a Kenko 25mm extension tube and that combo was then mounten on a Kenko MC7 2x converter. I stacked 17 exposures and then cropped to about 50% of the image to get a regular and abstracted almost rhythmic image. A highpass filter in Gimp accentuated a bit of sharpness.
