Test shots: “Generic Baskettail?”

February 15, 2019

larva/nymph in the Family Corduliidae (Emeralds) was collected by Bob Perkins on 02 December 2017 from a pond in Orange Park, Florida (USA). The larva died before it metamorphosed into an adult.

Test shots of this beautifully preserved specimen were taken using a small-ish aperture of f/11 for greater depth of field. The following photos are “one-offs,” that is, not composite images.

Dorsal

A single focus point — located on the thorax (specifcally, the “shoulder pad” along the right side of the body) — was used to shoot this photo. The specimen has enough “relief” that focus on the wing pads and dorsal hooks is slightly soft. This view of the larva is a good candidate for focus-stacking.

The terminal appendages (cerci, epiproct, paraprocts) are shown clearly in the following photo.

Bob’s best guess of the identity of the specimen is Epitheca sp., either Common Baskettail (Epitheca cynosura) or Prince Baskettail (Epitheca princeps).

Whenever I see an odonate larvae/exuviae with long legs, my first thought is Family Macromiidae (Cruisers). Then I check for a horn on top of the head, a key field marker for Cruisers. Look closely at the dorsal view of the larva and I think you’ll agree with me there appears to be a horn on the head. I would like to take close-up photos of the head and key out the specimen in order to determine its identity. In the meantime, my best guess is Stream Cruiser (Didmops transversa) as indicated by the lateral spines on abdominal segment nine (S9) and the absence of a dorsal hook on S10.

Ventral

The ventral side of the specimen has almost no “relief,” so a “one-off” focused on the thorax looks fairly good from head-to-tail.

Composite images: “Generic Gomphid”

February 13, 2019

“It’s like Deja vu all over again.” (Source Credit: Yogi Berra.) But seriously folks, if you were thinking “Hey these pictures look familiar!” then you’re right. My last blog post features “one-offs” of the same subject, that is, photos with a single focus point on the mid-body of the specimen.

This post features focus-stacked composite images that show dorsal- and ventral views of a preserved larva in the Family Gomphidae (Clubtails) that was collected by Bob Perkins. I think both composite images look better than the “one-offs” in my last blog post; the difference is especially noticeable by looking at the head and tail in the vernal view.

Dorsal

Five (5) photos were used to create the first focus stack. A single focus point was positioned over select anatomical features; photos were taken at each point of interest.

Test shots: “Generic Gomphid”

February 11, 2019

A larva/nymph in the Family Gomphidae (Clubtails) was collected by Bob Perkins from the New River in southwestern Virginia. The larva died before it metamorphosed into an adult.

Test shots of this beautifully preserved specimen were taken using a small-ish aperture of f/11 for greater depth of field. The following photos are “one-offs,” that is, not composite images.

Dorsal

80mm (120mm, 35mm equivalent) | ISO 200 | f/11 | 1/180 s | 0 ev

Bob’s best guess of the identity of the specimen is Phanogompus sp. I see several similarities between this larva and a Phanogomphus lividus exuvia (Ashy Clubtail) in my collection, so Bob’s tentative identification might be correct. More later after the specimen is keyed out.

Ventral

80mm (120mm, 35mm equivalent) | ISO 200 | f/11 | 1/180 s | 0 ev

This individual might be female, as indicated by the rudimentary ovipositor that can be seen on the ventral side of the specimen along the boundary between abdominal segments eight and nine (S8-9).

Gear used for studio macro photography.

By the way, in case you looked at the preceding photo and wondered “What’s up with the crazy crop?” I used Photoshop to conceal some of the clutter in my kitchen. I set up my macro photo rig in the kitchen because it’s the largest uncarpeted area in my tiny apartment. Padded carpet is a poor surface for macro photography — the field of view from a tripod-mounted camera-lens-flash trigger combo shifts noticeably (and unacceptably) as one moves around the rig.

The other side of “What is it?”

January 21, 2019

The following photograph shows the wooden side of a dragonfly rubber stamp.

The Backstory

On 26 December 2017, I published a blog post entitled “What is it?” I was testing my new Fujinon XF80mm macro lens used in combination with a Fujifilm MCEX-11 extension tube and needed a small subject to photograph. I was also testing my new Canon MT-26EX-RT Macro Twin Lite used in manual mode with my Fujifilm X-T1 digital camera.

In this case, I was testing — actually retesting — my new Fujifilm MCEX-16 extension tube. The last time I tested the 16mm extension tube, I used it in combination with an 11mm extension tube. Bottom line, I wasn’t happy with the results. So I decided to test the 16mm tube by itself, decrease the f-stop to a value closer to the sweet spot of the lens, and increase the exposure. Much better!

More test shots: Ladona deplanata exuvia

January 16, 2019

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.

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.

Test shot: Ladona deplanata exuvia

January 14, 2019

Bob Perkins collected and reared a Blue Corporal dragonfly (Ladona deplanata) larva/nymph. This is the exuvia from the nymph.

I took a series of test shots with the specimen in four poses: dorsal; dorsal-lateral; face-head; and lateral. The following photo is the dorsal view; other poses will be featured in one-or-more follow-up blog posts.

I was also testing two new pieces of photography gear: a Fujifilm 16mm extension tube; and a Godox X1R-C TTL Wireless Flash Trigger Receiver for Canon external flash units.

For more magnification, I combined my Fujinon XF80mm macro lens with Fujinon MCEX-11 and MCEX-16 extension tubes.

My Canon 580EX II Speedlite features two wireless modes: optical master and optical slave; it does not feature wireless radio master/slave modes. Having said that, if the Canon 580EX II external flash is mounted on a Godox X1R-C, then the Canon flash can be triggered by wireless radio using a Godox XPro-series flash trigger.

For example, I mounted a Godox XProF TTL Wireless Flash Trigger for Fujifilm cameras on my Fujifilm X-T1 digital camera. During limited testing, I discovered both my Canon 580EX- and 580EX II Speedlites fire when mounted on an X1R-C, with the following caveats: the flashes are set for Manual Mode only, at shutter speeds less than or equal to 180s (the sync speed of the XT-1 camera); neither TTL nor HSS works.
