Test shots: Stylogomphus albistylus exuvia

Bob Perkins collected and reared an Eastern Least Clubtail dragonfly (Stylogomphus albistylus) nymph. This blog post features two focus-stacked composite images of the exuvia from the odonate nymph.

Nine photos were used to create the first focus stack. This small specimen features several easy-to-recognize field marks including large, dish-shaped antennae, distinctive color bands on the legs, lateral spines on abdominal segments eight and nine (S8-9), and terminal appendages tipped with a lighter color.

12 photos were used to create the last focus stack. This individual might be a male, as indicated by what appear to be vestigial hamules on the ventral side of the specimen.

Tech Tips

The following equipment was used to shoot all of the photographs for the two focus-stacked composite images, shown above: Canon EOS 5D Mark II digital camera, in manual mode; Kenko 20mm macro automatic extension tubeCanon EF100mm f/2.8L Macro lens (set for manual focus); and Canon MT-26EX-RT Macro Twin Lite set for “Master” mode, and several external flashes set for “Slave” mode including Canon 580 EX- and Canon 580EX II Speedlites and a Godox TT685C Thinklite TTL Flash fitted with a Lastolite Ezybox Speed-Lite 2 flash modifier.

Adobe Photoshop CC 2017 was used to create the focus-stacked composite images, as well as spot-heal and sharpen the final output.
