Tethered

April 13, 2021

“Tethered.” What does that word mean to a photographer? In its simplest sense, it’s when a camera is connected to a computer either by some type of cable or sometimes wirelessly.

“Tethered shooting” implies the photographer is able to control the camera remotely, either partially or completely.

Is there really a distinction between the two terms? I think so.

In my last two blog posts I mentioned that my older Fujifilm X-T1 mirrorless digital camera cannot be used for tethered shooting using either the free Fujifilm X Acquire 2 software or via some sort of HDMI Video Capture device. That being said, the Fujifilm X-T1 camera can be tethered to my computer in order to display the output from the HDMI port on the camera.

The section entitled “Viewing Pictures on TV” that appears on p. 108 of the Fujifilm X-T1 Owner’s Manual is shown below.

When the Fujifilm X-T1 is connected to my Apple MacBook Air computer via a MavisLink Video Capture Card and displayed on-screen using OBS Studio, the camera thinks the computer is a TV. Well, sort of.

OBS Studio | Properties for ‘Video Capture Device’

First, add a “Video Capture Device” to a “Scene” in OBS Studio. Select “USB Video” since the “HDMI Video Capture” device connects to the computer via USB. A colorful test pattern appears on screen, even when the camera is turned on.

When the “Play” button on the back of Fujifilm X-T1 camera is pressed, a small green LED in the upper-right corner of the camera turns on and the photos saved to the memory card in your camera are shown on-screen, one image at a time. Use the “D” pad on the back of the camera to cycle through all of the photos on the memory card. Press the “Play” button when you’re finished and the test pattern reappears in OBS Studio.

By the way, the photo shown in the preceding “Screenshot” of OBS Studio is one of the images I shot for Sumo Citrus still life, a recent blog post.

What is it?

April 6, 2021

Ladies and gentlemen, children of all ages. It’s time for another exciting episode of “What is it?”

This episode is a little different because the name of the mystery item is printed clearly on the product itself. I guess the real mystery is two-fold: What does the acronym “HDMI” mean, and what does this video capture device do?

“HDMI” stands for “High-Definition Multimedia Interface.” The MavisLink Video Capture Card converts HDMI 4K 60FPS (from your digital camera) to USB 1080P 60FPS (on your computer) that can be either recorded or live streamed on video conferencing services.

“MavisLink” is a brand name that was recommended by Graham Houghton, a gentleman whose expertise I respect and opinion I value. It’s worth noting a quick Web search will reveal lots of video capture cards sold under different brand names that look identical to the MavisLink device shown above. Do they work as well as the one recommended by Graham? Who knows?

I plan to use the device in combination with Open Broadcaster Software (OBS Studio) to record the video and audio output from some of my digital cameras; the saved video clips will be featured in future “how to” blog posts.

So far I have tested the process with several of my cameras: My Panasonic Lumix DMC-FZ300 and Fujifilm X-T3 work; my Fujifim X-T1 doesn’t work.

I still need to test my older Canon EOS 5D Mark II. It should work but as far as I know the camera doesn’t feature “clean HDMI” output, that is, some or all of the info display on the camera viewfinder/LCD (e.g., the focus rectangle) is included in the output.

Sumo Citrus still life

March 19, 2021

Have you seen/eaten Sumo Citrus? They’re easy to peel, seedless, and billed as “the sweetest orange.” Delicious, I say!

How I got the shots

I set up a tripod at a good distance from the subject for a 50mm lens. Then I switched cameras without moving the tripod. Each camera/lens combo was set for an aperture of f/8; other camera and flash settings varied as necessary. (See EXIF info for details regarding camera settings for each photo.)

Sumo Citrus from Giant Food

Bernard Nimmons is the produce manager at the Giant Food located in Beacon Center. I sent a Facebook Messenger message to Bernard recently…

I need Sumo Oranges STAT! Are they back in stock?

The following selfie photo is Bernard’s reply to my message. Now you can see why I always say “Bernard puts the ‘Pro’ in Produce.”

Matchbox Monday

November 30, 2020

The Matchbox MBX Construction II set of toy vehicles.

I love toys — always have and always will. When I was a young boy, I was especially fond of toy dinosaurs, Matchbox vehicles, and building scale models, to name a few.

I always check the toy department whenever I visit stores that stock, well, toys. I was delighted to find a small selection of Matchbox toys during a recent trip to Target. After looking at every box hanging on a display wall, I chose the MBX Construction II set. In my opinion, commercial vehicles have more character than say most automobiles.

According to the side panel of the packaging, the following vehicles are included in the toy set (from right to left, relative to the preceding photo): Matchbox Skidster; 1966 Dodge A100 Pickup; Matchbox Water Worker; Man TGS Dump Truck; and 2014 Chevy Silverado.

Post Update

I stumbled across a YouTube video that features two favorite Lesney Matchbox toys from my childhood: the yellow “Evening News” van; and the red double-decker bus.

As I mentioned in the comments for this post, I need to find my old Matchbox toys!

The last rose of summer

November 16, 2020

The Last Rose of Summer is a poem written in 1805 by Irish poet Thomas Moore.

15 NOV 2020 | The Beacon of Groveton | rose bud

“You look like the last rose of summer” was one of my Irish mother’s favorite sayings. Miss you, Mom!

Tech Tips

A rose bud cutting from the landscaping at The Beacon of Groveton was photographed against a pure white background (255, 255, 255) using the “Meet Your Neighbours” (MYN) technique.

I used my Fujifilm X-T1 digital camera and an 18-55mm zoom lens, set for 55mm. One external flash was used to backlight the background (a piece of translucent white plastic) and another flash was used as a key light on the subject. Check the EXIF/IPTC info for the photograph for complete details regarding photo gear and camera settings.

Laowa LED Ring Light for 25mm Ultra Macro Lens

October 9, 2020

I prefer artificial light from electronic flash units rather than continuous light sources such as LEDs. That being said, when the working distance between lens and subject is small, a lens-mounted LED ring light makes sense to use.

Minimum focusing distance versus working distance

The “minimum focusing distance” is the distance from the subject to the focal plane. The “working distance” is the distance from the front of the lens to the subject. For macro photography, usually the latter is more important than the former.

According to Venus Optics (Laowa), the minimum focusing distance for the “Laowa 25mm f/2.8 2.5-5x Ultra Macro lens” is 23.4 cm at 2.5x magnification and 17.3 cm at 5x. According to several Web sites, the working distance is 45 mm (4.5 cm) at 2.5x and 40 mm (4.0 cm) at 5x, or a range of working distances from ~1.8 to ~1.6 inches.

Adding one or more extension tubes reduces the working distance and increases magnification. For example, adding a Kenko 12mm extension tube reduced the working distance from 45 mm to ~30 mm at 2.5x.

And it’s worth noting that adding the Laowa “Canon EF lens to Fujifilm X mount camera adapter” to the lens further reduces the working distance — the adapter is ~26 mm wide, essentially equivalent to adding a 26mm extension tube. Combined with the 1.5x crop factor of Fujifilm X-Series cameras such as the X-T1 and X-T3, it’s no wonder the magnification of the lens is increased dramatically when used with select Fujifilm cameras!

Ultra Macro Lens

The first two photos, courtesy B&H Photo, show the version of the Laowa lens for Canon EF. For what it’s worth, f/4 is the “sweet spot” for this lens.

Look closely at the front of the lens. Notice a “flange” (one of two) that is visible around the outer rim of the lens. Those flanges are used to mount the Laowa LED ring light on the lens.

LED Ring Light

The next two photos, courtesy Allen’s Camera, show the Laowa LED ring light.

The LED ring light ships with a USB power cable. A power source for the ring light is NOT INCLUDED. My next blog post will feature a discussion of the pros/cons of the power source solution I decided to use.

LED mounted on lens

The last photo shows the Laowa LED Ring Light mounted on the Laowa Ultra Macro Lens that is mounted on my Canon 5D Mark II digital camera. The USB power cable is connected to the LED ring light but not connected to a power source. (Don’t mind the clutter in the background!)

Notice the face of the LED ring light extends ~5 mm beyond the front of the lens, thereby reducing the working distance by ~5 mm (~0.5 cm). Plan accordingly.

Macromia illinoiensis exuvia (face-head) redux

May 22, 2020

A Swift River Cruiser dragonfly (Macromia illinoiensis) exuvia was collected, with permission from park staff, on 27 May 2017 along the Potomac River at Riverbend Park in Fairfax County, Virginia USA.

The preceding image shows the remnant ommatidia clearly.

From this viewpoint, it’s harder to see the prominent horn on the face that is a key field mark for larvae/exuviae in the Family Macromiidae (Cruisers). The base of the triangular horn is located above the labium (face mask), between the long, thin antennae; the apex of the triangle is pointed toward the viewer.

It’s easier to see the horn in the featured photo in my last blog post.

Tech Tips

The subject was photographed against a pure white background (255, 255, 255) using the “Meet Your Neighbours” (MYN) technique.

20 photos of the specimen were taken using 2.5x magnification at an aperture of f/4; 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.

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.

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.
