MYN – More Pantala hymenaea exuvia

December 18, 2019

An odonate exuvia was photographed against a pure white background using the “Meet Your Neighbours” (MYN) technique.

This specimen is a Spot-winged Glider dragonfly (Pantala hymenaea) exuvia. Spot-winged Glider is a member of Family Libellulidae (Skimmers).

The Backstory

This specimen was collected (near Richmond, Virginia USA) and identified by Andy Davidson. Andy is a graduate student at Virginia Commonwealth University working on a research project entitled “Predator-Prey Interactions in a Changing World.”

Tech Tips

The following equipment was used to shoot the macro photographs featured in this post: Fujifilm X-T1 digital camera; Fujifilm MCEX-11 extension tube; and Fujinon XF80mm macro lens minus the lens hood. The camera was set for both manual exposure and manual focus. That’s right, a switch on the camera body is used to set the type of focus. It’s a Fujifilm thing.

Godox XProF radio flash trigger, mounted on the hotshoe of my X-T1, was used to control two off-camera external flash units set for radio slave mode.

  1. Godox TT685C Thinklite Flash for Canon Cameras (manual mode), fitted with a “Vello Bounce Dome (Diffuser) for Canon 580EX II Flash,” was used to light the underside of the translucent white plastic background; the top of the flash unit was ~30 cm from the bottom of the white plastic.
  2. A Godox TT685o/p Thinklite Flash for Olympus/Panasonic Cameras (manual mode), fitted with a Lastolite Ezybox Speed-Lite 2 flash modifier, was used to light the subject from above.

Godox XProF – TCM Function

November 6, 2019

Godox makes two types of wireless flash triggers (radio) that are compatible with Fujifilm X Series digital cameras, listed from less expensive to more expensive: the Godox X2TF; and the Godox XProF. Both flash triggers have essentially the same functions. The X2TF has a slightly lower price point than the XProF, smaller footprint, and a pass-through hot-shoe; it lacks the TCM Function featured on the XProF.

TTL

“TTL” stands for “Through The Lens” metering. Some external flash units, such as the Godox TT685F Thinklite TTL Flash for Fujifilm Cameras, are TTL-compatible, meaning the camera will set the flash power ratio automatically for proper exposure. So what’s not to like about that?

A photographer has no way of knowing what the flash power setting is when using an external flash unit in TTL mode. Some photographers might be surprised to learn that TTL exposure can vary from one shot to another, often quite noticeably. That can be a problem. For example, repeatability is a big concern in macro photography, especially when creating focus stacks. So what’s the solution? TCM Function.

TCM Function

“TCM Function” is a proprietary feature of the Godox XProF that stands for “TTL Converted to Manual,” translated loosely. Here’s how it works.

The “Magnification/TCM Button” (shown below) is a toggle switch: a short-press switches the display on the LCD panel back-and-forth from the settings for all off-camera flash groups (A-E) to a magnified view of the settings for one group, e.g., Group A (that can include one or more external flash units); a long-press activates the TCM Function.

Godox XProF Instruction Manual.

Set the XProF for TTL mode. Take a test shot, then long-press the TCM button. You should see the display on the XProF switch from TTL mode to Manual mode, showing the equivalent manual settings for the TTL test shot.

Godox XProF Instruction Manual.

This feature can be useful for quickly determining a good starting point for setting external flash units in Manual mode. Try it. I think you’ll like it!

Take-aways

Which model Godox radio flash trigger should you buy, the X2TF or the XProF? That depends upon what’s more important to you — either the pass-through hot shoe or TCM Function. You can have one feature or the other but you can’t have both in a single flash trigger.

Dragonflies rock!

May 15, 2019

I received a surprise parcel in the U.S. Mail from my dear friend Susan Kinsley. There was a cover note inside the box…

The church where I work has a ministry where they paint rocks and then place them in the community for people to find to brighten their day. When I saw this one in the basket, I decided that you needed to have it. The woman in charge of the ministry gave me permission to take it and send it, rather than trying to hide it at Huntley Meadows or somewhere you might, or might not, find it. Enjoy! Susan

There’s a friend who knows me well. Thanks for thinking of me, Susan. God bless you!

Aging gracefully

March 1, 2019

The following gallery features several photos of a Valentines Day gift of appreciation from The Beacon of Groveton. A little more than two weeks after the red rose was delivered, the flower appears to be aging gracefully.

I experimented with a different lighting setup than the last photo shoot of this flower. An articulating Loc-line arm was used to hold and pose the cut flower. The background is a 12″ x 12″ piece of white plastic, mounted vertically and backlighted by a radio-controlled external flash unit. Notice the vignetting on the left side of the photo, caused by the flower being offset from the center of the sweet spot of the backlight.

28 FEB 2019 | BoG Photo Studio | Valentines Day rose

The simplest solution to the vignetting problem is to crop the image. Ah, much better, and much closer to achieving my vision for the finished product — the red rose posed against a clean white background!

The next photo is the only photo in the set that turned out exactly as I wanted. Well, the flash in Group B (off camera, to the front-left of the subject) is a little too bright, but that’s just the perfectionist in me talking.

28 FEB 2019 | BoG Photo Studio | Valentines Day rose

The first two photos were taken at f/8. I moved the camera closer to the subject for the last photo and switched to f/11 for more depth of field. The shadow of the flower stem on the white background wasn’t part of my plan — I’m not sure whether it adds to the photo or detracts. What do you think?

…and smell, er, see the roses. Seriously, man doesn’t live by odonates alone!

The following gallery features several photos of a Valentines Day gift of appreciation from The Beacon of Groveton. Nearly a week after the red rose was delivered, it’s beginning to show a little “character.”

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.

“Generic Baskettail” larva (preserved specimen) | Orange Park, FL USA

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 power!

January 18, 2019

Like Tim “The Tool Man” Taylor, I like/need more power. (Grunt, grunt.) Regular readers of my photo blog know that I have purchased several new external flash units and related accessories, all of which use batteries as their power source.

Panasonic eneloop pro rechargeable batteries and Ansmann Battery Boxes are my current favorite brands.

Panasonic eneloop pro rechargeable batteries | Ansmann Battery Box

Look closely at the full-size version of the preceding photo. Notice that the month and year I bought the batteries is written on the side of each battery using a Sanford’s Sharpie permanent marker. I do this for two reasons. First, it’s easier to group/use batteries of the same vintage. Second, it’s easier know when it’s time to replace a set of batteries that doesn’t hold a charge as long as it used to.

The little things matter in photography. Little things like batteries, especially when you’re photowalking in the field. I always carry at least two boxes of four batteries per box.
