More experimentation with tethered shooting

August 12, 2020

Oh no! I have become the blogger who cried wolf. Yes, I’m guilty of over-promising and under-delivering. I promise to do better. Oops, I did it again! (Queue Britney Spears…)

Why tethered shooting?

In case you’re wondering what piqued my interest in tethered shooting, I was bored. I had figured out all there is to know about non-tethered shooting so I needed a new challenge. Not!

Tethered shooting enables me to quickly check composition, exposure, and focus, to name a few advantages of tethered versus non-tethered shooting — on a larger screen than the LCD on the back of my cameras.

Bear in mind, I don’t want to edit the photo files using my laptop computer (Apple 13″ MacBook Air) — I prefer to use my desktop computer (Apple 24″ iMac) for photo editing.

Latest testing

The following photos were taken by tethering my Fujifilm X-T3 digital camera to an Apple 13″ MacBook Air computer, via a TetherTools USB cable. FUJIFILM Tether Shooting Plug-in PRO was used to save JPG files to a folder on the desktop of my MacBook Air; in turn, the JPG images were displayed in Adobe Lightroom. Both JPG and RAF files were saved to one of two memory cards in the X-T3.

Notice the difference in way these two photos were lighted. Both shots were taken using a single off-camera flash. The position of the flash resulted in more- or less dramatic light. Each shot shows something better than the other, so I was unable to choose a clear favorite. What’s your preference?

Tips and Tricks

Oh yeah, the tips and tricks I have been promising are still in the pipeline. I made some screen grabs today to illustrate the process of tethered shooting. Turns out I overlooked a critical setting so all of the graphics are useless. Doh! Can you say “Do over”?

As promised…

August 9, 2020

A rare weekend blog post

The following photo was taken by tethering my Fujifilm X-T3 digital camera to an Apple 13″ MacBook Air computer, via a TetherTools USB cable. Fujifilm X Aquire (free) was used to save JPG files to a folder on the desktop of my MacBook Air; both JPG and RAF files were saved to one of two memory cards in the X-T3.

Apple “Preview” was used to view the JPG files saved to my MacBook Air. Looking at larger versions of the photos than can be seen on the X-T3 LCD enabled me to position the exuvia exactly as I wanted.

Notice the left eye is overexposed slightly (as well as the farthest tip of the left middle leg), probably caused by positioning the subject too close to the white background. Hey, it’s been a while since I did much studio macro photography — I need to play myself into game shape!

More details, including some of the tips and tricks I promised, will be provided in my regularly-scheduled blog post on Monday, 10 August 2020. Please stay tuned!

First foray into tethered shooting

August 5, 2020

My first foray into tethered shooting occurred on 01 August 2020. Although I felt like I had no idea what I was doing, I was able to successfully connect my Fujifilm X-T3 digital camera to an Apple 13″ MacBook Air computer, via a TetherTools USB cable. The screen on my laptop shows the display for the FUJIFILM Tether Shooting Plug-in PRO (Mac) for Adobe Lightroom.

Screen display for 13″ MacBook Air.

I will backfill this post with more details about the hardware and software used to capture the following image, taken a few days after “first light.” In the meantime, I’m SO LATE in publishing my blog post for Wednesday I just want to put something out there STAT. Please revisit this post at a later time to read the updated version.

A Swift River Cruiser dragonfly (Macromia illinoiensis) exuvia was collected on 27 May 2017 along the Potomac River at Riverbend Park in Fairfax County, Virginia USA. This individual is a female. Notice the prominent horn on the head, a key field mark for exuviae from Family Macromiidae (Cruisers).

Ignore the bad background and quick-and-dirty lighting — this photo isn’t so much about making a good macro photo as it is the process used to make it. More later…I promise!

Macromia illinoiensis exuvia (face-head)

May 20, 2020

The following photograph of a Swift River Cruiser dragonfly (Macromia illinoiensis) exuvia shows a prominent horn on the face that is a key field mark for larvae/exuviae in the Family Macromiidae (Cruisers).

The specimen was collected, with permission from park staff, on 27 May 2017 along the Potomac River at Riverbend Park in Fairfax County, Virginia USA.

Tech Tips

The subject was photographed against a pure white background (255, 255, 255) using the “Meet Your Neighbours” (MYN) technique. The specimen was posed on its dorsal side, so the camera was focused on the face-head-ventral view of the exuvia. The final image was cropped and rotated 180° during post-processing.

10 photos of the specimen were taken using an aperture of f/16; in-camera focus peaking was used to highlight select areas in each photo. RAW FILE CONVERTER EX 3.0 was used to convert Fujifilm RAF files to TIFF files. Adobe Photoshop CC 2017 was used to create a focus-stacked composite image that was edited using Apple Aperture.

Editor’s Note: This blog post is the last installment in what turned out to be a three-part series. The featured focus-stacked composite image is a little closer to what I had in mind when I set up the photo shoot.

MYN – Macromiidae larvae/exuviae are horny

May 15, 2020

A prominent horn on the face is a key field mark for larvae/exuviae in the Family Macromiidae (Cruisers), as shown in the following photograph of a Swift River Cruiser dragonfly (Macromia illinoiensis) exuvia.

The base of the triangular horn is located above the labium (face mask), between the long, thin antennae.

The specimen was collected, with permission from park staff, on 27 May 2017 along the Potomac River at Riverbend Park in Fairfax County, Virginia USA.

Tech Tips

The subject was photographed against a pure white background (255, 255, 255) using the “Meet Your Neighbours” (MYN) technique. The specimen was posed on its dorsal side, so the camera was focused on the face-head-ventral view of the exuvia. The image was rotated 180° during post-processing.

My vintage 2009 Apple iMac desktop computer is too old to support drivers for importing RAF files from my Fujifilm X-T3 mirrorless digital camera into either Apple Aperture or Adobe Lightroom.

The work-around is to use a free application from Fujifilm that converts RAF files to TIFF files, which can be opened and edited with Aperture and Lightroom. Problem is I’m a big procrastinator and haven’t learned how to use the file converter application, so I simply edited one of the JPGs straight from the camera.

For the most part, the finished image looks fairly good although the eyes are blown out a little to a lot. JPG files have less dynamic range than RAF files so I was unable to recover the blown highlights.

Hmmm, it might be time to buy a new desktop computer!

Post Updates

I finally got around to figuring out how to use the free Fujifilm application to convert RAF files to TIFFs. See my follow-up blog post entitled “RAW FILE CONVERTER EX 3.0” for step-by-step instructions.

10 photos (converted from RAF to TIFF), including the one-off featured in this blog post, were used to create a focus-stacked composite image of the specimen that is a little closer to what I had in mind when I set up the photo shoot.

Focus bracketing using Fujifilm X-T3

May 11, 2020

In-camera focus bracketing was used to shoot 35 photos automatically. Adobe Photoshop CC 2017 was used to create the focus-stacked composite image shown below.

Focus-stacked composite image

The toy is a Poliwrath, one of many Pokemon characters. The 7″ plastic ruler is from the Calvert Marine Museum. Do you know why the small ruler is 7″ long rather than the more common 6″ length? Please leave a comment if you know the correct answer.

Photo No. 1

The camera was focused manually on the closest point in the foreground, before pressing the shutter button.

80mm (120mm, 35mm equivalent) | f/8 | 1/250s | ISO 160 | 0 ev

Select photos from the 35-photo set show the focus point advancing automatically from the foreground to background.

Photo No. 5

80mm (120mm, 35mm equivalent) | f/8 | 1/250s | ISO 160 | 0 ev

Photo No. 20

80mm (120mm, 35mm equivalent) | f/8 | 1/250s | ISO 160 | 0 ev

Photo No. 35

80mm (120mm, 35mm equivalent) | f/8 | 1/250s | ISO 160 | 0 ev

Tech Tips

Minimal effort was invested in arranging the subjects and lighting the scene.

Some trial and error is required in order to determine the correct focus bracket settings for a given combination of camera and lens, in this case, my Fujifilm X-T3 and 80mm macro lens.

As it turns out, I shot six sets of test shots before I found settings that worked the way I wanted. The following settings were used to shoot the 35 photos for the focus-stacked composite image featured in this post: Frames = 35; Step = 10; Interval = 3 s.

The camera was set to save files as FINE+RAW. In the interest of expediency, the composite image was created using JPGs straight from the camera. Photo No. 1, 5, 20, and 35 are also unedited JPGs.

What are the take-aways?

The technique works as advertised and should help to save time by automating the most tedious part of the process of creating focus stacks. Further experimentation is planned.

MYN – Hylogomphus adelphus exuvia (dorsal)

May 4, 2020

The following Anisoptera exuvia — collected by Freda van den Broek on 10 June 2019 along the St. Croix River in Polk County, Wisconsin USA — is definitely a member of Family Gomphidae (Clubtails), probably Mustached Clubtail (Hylogomphus adelphus).

Dorsal view

The abdomen is wider than the head. Vestigial mid-dorsal hooks are noticeable along several abdominal segments, especially segment nine (S9). A “median groove” is apparent along part of the abdomen. The lateral spine on S9 is spinulose-serrate along the outer edge.

MYN – Hylogomphus adelphus exuvia (ventral)

May 1, 2020

The following Anisoptera exuvia — collected by Freda van den Broek on 10 June 2019 along the St. Croix River in Polk County, Wisconsin USA — is definitely a member of Family Gomphidae (Clubtails), probably Mustached Clubtail (Hylogomphus adelphus).

Ventral view

Notice the exuvia has a flat labium (prementum). There are lateral spines located on abdominal segments six through nine (S6-S9); the lateral spine on S9 is spinulose-serrate along the outer edge. Also notice the well-developed tibial burrowing hooks on its legs.

10 JUN 2019 | Polk County, WI | H. adelphus exuvia (ventral)

Male (vestigial genitalia)

Male odonates have two sets of sex organs: primary genitalia located on abdominal segment nine (S9); and secondary genitalia located on abdominal segments two-to-three (S2-3).

Both sets of vestigial genitalia are clearly visible on the ventral side of some (but not all) specimens, such as the H. adelphus exuvia shown above.

MYN – Too dark or too light?

April 27, 2020

The following Anisoptera exuvia — collected by Freda van den Broek on 10 June 2019 along the Red Cedar River in Barron County, Wisconsin USA — is definitely a member of Family Gomphidae (Clubtails), possibly Rusty Snaketail (Ophiogomphus rupinsulensis).

Dorsal-lateral view

Nine (9) photos of the specimen were taken using an aperture of f/16; in-camera focus peaking was used to highlight select areas in each photo. Adobe Photoshop CC 2017 was used to create the focus-stacked composite image shown below.

10 JUN 2019 | Barron County, WI | Anisoptera exuvia (dorsallateral)

When I previewed the RAW files used to create the preceding composite image, I thought most of the files look too dark.

So I did a do-over using 15 photos, resulting in a new version of the composite that is perfectly in focus but a little too light. Compare/contrast the two composite images and you should notice it’s easier to see the mid-dorsal hooks along the abdomen in the first image. The primary purpose for the images is to illustrate those field marks, therefore I think the first (darker) image is better.

10 JUN 2019 | Barron County, WI | Anisoptera exuvia (dorsallateral)

Face-head-dorsal view

Five (5) photos of the specimen were taken using an aperture of f/16; in-camera focus peaking was used to highlight select areas in each photo. Adobe Photoshop CC 2017 was used to create the focus-stacked composite image shown below.

10 JUN 2019 | Barron County, WI | Anisoptera exuvia (face-head-dorsal)

My first impression of the version shown above is it’s too dark, and I second-guessed myself for not shooting more photos for the focus stack.

I created a new focus-stacked composite image using a little more light and 14 photos. When I examined the RAW files used to create the new composite image (shown below), I thought most of the files still look too dark. (But I was wrong.)

10 JUN 2019 | Barron County, WI | Anisoptera exuvia (face-head-dorsal)

So I created a third version using much more light and 24 photos. Although it’s debatable which image looks best, the first- and second images show a few key field marks of the antennae better than the third image.

It turns out the antennae are one indicator this specimen is from the genus Ophiogomphus (Snaketails), so the first two (darker) images are the winners once again.

10 JUN 2019 | Barron County, WI | Anisoptera exuvia (face-head-dorsal)

For what it’s worth, the second of three images is my favorite as indicated by the fact that the image is cropped so there’s room for annotations.
