24mp dslr, 40mm macro lens, speedlite flash, tripod and computer trickery to stack the slices that are in focus together, make the shadows brighter and the overall colour more natural.
If you want specifics the exposure time was 1/200 of a second, the iso set at 100, the aperture was set to 10, the flash to 1/16 strength and I manually focused the lens
Sounds like the only thing you are missing is a remote trigger . Are you shooting in j-peg, or raw?
