More test shots: Ladona deplanata exuvia

As promised, this blog post features more test shots of the exuvia from a Blue Corporal dragonfly (Ladona deplanata) larva/nymph collected and reared by Bob Perkins.

All of the images in this photo set (including the dorsal view featured in my last blog post) are underexposed, except for the following photo: this photo looked overexposed on my camera LCD; the rest of the photos looked fine.

In reality, the photos were underexposed because I didn’t compensate for the effect of the extension tubes on exposure — a problem that was probably caused/exacerbated by switching the ISO from my usual setting of “A” (Auto) to 200. This photo turned out to have the best exposure because the flash power was several stops higher than the rest of the photos in the set. Remember the exposure triangle. (See Tech Tips/Related Resources, below.)

Oh, so close to a good shot! The left front leg blocks part of the face-head, and that doesn’t work for me. This specimen is a good candidate for rehydrating the exuvia and reposing its legs.

Tech Tips

The following equipment was used to shoot the preceding photo: Fujifilm X-T1 digital camera; Fujifilm MCEX-11 and MCEX-16 extension tubes; Fujinon XF80mm macro lensGodox XProF TTL Wireless Flash Trigger for Fujifilm camerasGodox TT685F Thinklite TTL Flash for Fujifilm CamerasGodox TT685C Thinklite TTL Flash for Canon Cameras fitted with a Lastolite Ezybox Speed-Lite 2 flash modifier; and Canon 580EX II Speedlite mounted on a Godox X1R-C TTL Wireless Flash Trigger Receiver for Canon.

Adobe Photoshop CC 2017 was used to spot-heal and sharpen the final output.

What you should remember, as a rule of thumb, is that by the time you get close to magnifications of 1:1, the effective f-stop of the lens will have changed by about 2 stops. That means you, or your camera, are needing to compensate for this with a higher ISO, or a shutter speed that’s 4-times longer than you’d need without those tubes.
