The first Wildlife Photography Exhibition represents the finest of the images produced and selected by students of the new Wildlife Photography Program at Texas A&M University- Kingsville. Students created images to best depict Texas wildlife and its habitat. The class members produced these images during the Spring 2018 semester and printed and prepared the mounted images for the May exhibit at the Caesar Kleberg Wildlife Center in Kingsville, Texas.
BEST IN SHOW- “It’s a Small World”- Kelley Wood
“This ladybird beetle was on a Honey Mesquite (Prosopis glandulosa) inflorescence. I was looking at the plant because there were multiple butterflies and other insects that I wanted to take pictures of. It was in the shade, so the lighting was not as harsh.”
BEST HABITAT- “Bobcat”- David Campbell
“I was on the ranch I work on near Cotulla, TX heading to one of our ponds with a fishing pole and cold beer in hand. As I got near the water I noticed this bobcat sitting on the edge of the brush and realized I didn’t have my camera. I watched him for a second and decided to go back to the truck (a couple hundred yards away) to get my camera. To my surprise he had not moved an inch which allowed me to take this and several other great photos.”
BEST WILDLIFE- “Burrowing Owl”- Alex Meza
“Photographed in Granjeno, Texas, a small town literally at the edge of the Rio Grande River. This owl nests in crevices created by big boulders that are placed next to the levee to protect citizens from the Rio Grande River flash floods. The Burrowing owl was out in the sunset after a hot day in South Texas.”
WILDLIFE PHOTOGRAPHY PROGRAM
The new Wildlife Photography program is an unique-in-the-nation curriculum providing classes to biology majors within the Range and Wildlife Sciences department at the university. The program was started through a generous donation by the Frederick J. Bremner Trust. Dr. Bremner was a former faculty member at Trinity University in San Antonio.
The program began this Spring 2018 semester with the first in a series of classes entitled Introduction to Digital Wildlife Photography. Additional classes include: Advanced Digital Wildlife Photography, Wildlife Macro Photography, Wildlife Photographic Technology, and Digital Post Production in Wildlife Photography.
The program was developed by Brian Loflin, a Austin biological photographer, author and educator who has taught similar classes at UT Austin Continuing Education and Informal Classes for the past eleven years and in seminars and workshops throughout the country. Loflin is a adjunct faculty member at Texas A&M University- Kingsville.

Brackettville, Tex.- October 2, 2017
A new program for Wildlife/Biology majors at Texas A&M University-Kingsville (TAMUK) has been implemented by a generous donation from the Frederick J. Bremner Charitable Trust. The program includes a thirty-hour course of study in biological and wildlife photography, classroom and laboratory equipment and professional digital cameras and accessories for student use when enrolled. When fully established, this academic program will be the only one of its kind within a university setting in the United States.
Bremner Trustee Sandy Hurwitz said, “The trust was charged in finding a home for this donation in the center of a robust educational environment that can make a difference in habitat understanding and outdoor utilization. We believe that TAMUK is the perfect home for this program and we want to make TAMUK the unquestioned world leader in Wildlife Photography and Eco Tourism. As an educator, mentor and outdoorsman, Fred Bremner would be exceptionally thrilled with this new program.”
Dr. Fred Bremner, professor emeritus of psychology at San Antonio’s Trinity University, died June 30, 2016 at 80 years of age. A specialist in the relationship between the brain and behavior, Bremner joined the Trinity faculty in 1965 as an associate professor. Promoted to full professor in 1974, he served twice as chair of the Department of Psychology before retiring in 1999.
Dr. Bremner had a great love for horses and the outdoors and enjoyed teaching his students to ride, hunt, train bird dogs, and fish. He established the Frederick J Bremner Charitable Trust to continue his life’s work in promoting these passions.
Housed within the Caesar Kleburg Wildlife Research Institute at TAMUK, the new Wildlife Photography Program will provide students in the Bachelors, Masters and Doctorate programs an additional avenue to enhance their professional career through biological and wildlife photography. The purpose of the grant is to address the need to educate current and future students at the university level to serve the fast-growing needs of the millions of people in Texas and globally who are traveling to enjoy and photograph wildlife and nature.
The students will learn to make our public parks, private ranches, urban greenbelts, wildlife preserves and other wild places accessible and productive for wildlife photographers while preserving and enhancing the environment of the open spaces that the increasing number of ecotourists and photographers are utilizing. Every one of us that goes out into the field to photograph birds and wildlife clearly understands the need for more and better venues to enjoy our passion. The ultimate goal is to promote the Conservation and enjoyment of our Natural Environment through photography and ecotourism.
TAMUK is one of the most active and respected research universities in the world in the discipline of Wildlife Science. As a tool for research in the natural sciences, Digital photography is a tool on the cutting edge in providing new methods and practices in measurement, analysis and integrity in publication. As a tool in ecology and the environment, digital photography is very effective in attracting more people to the outdoors to better understand and appreciate our wild places. Wildlife photography also stimulates eco-business and nature tourism on a large scale beyond the scope of biological science.
These programs in wildlife photography and ecotourism will produce TAMUK graduates that will fill thousands of entirely new, well-compensated, high-quality professional jobs in rural Texas, and rural America that are not exportable to China, India or downtown Dallas.

Capturing the inflight antics of hummingbirds, like this Black-chinned female, poses a number of challenges. We have to think about getting them where we want them to be, to be in focus, to have a good exposure, and to be sharp with wing feathers rendered in fine detail.
With today’s digital cameras, automatic technology makes some of this possible. But to get truly refined in-flight images of these little jewels, requires a bit more than camera and high shutter speeds alone. So multiple off-camera, electronic flashes is the only way to go.
To get the flying hummer where we want it, requires placing a feeder with one feeding port in the shade. Shade is important because we need the high speed capability of the off-camera flashes to work for us to stop the motion and wing beat of the hummers. If the set is placed in the sun, most flashes don’t have the power at high speed to compete with the sun for proper exposure.
The real key to this method is to let the electronic flash do the work for you. They are designed to produce crisp, daylight-white light, and at a very fast flash duration. Today’s Speedlights can produce a flash duration as short as 1/40,000 second.
But that speed is not to be achieved at full power. That full-power flash duration may be as long as 1/900 second, much longer. The short flash duration therefore, comes at a trade-off of output light intensity (or exposure, if you wish). Therefore we must be in the shade to overpower the sun. Two flashes on the bird provides additional exposure for increased apertures and better Depth of Field. Place the flashes on stands and synchronize them with the camera using cables, radios or IR triggers or the flash eTTL / iTTl technology. The flash sync does not need to be TTL as everything is in manual mode. The light intensity at the bird may be controlled by simply changing the flash-to-subject distance.
Once the feeder is set up and hummingbirds are using it frequently, it’s time to bring in the other equipment, including camera, flashes on their stands, and the background. It may take a few minutes for the birds to become settled down with all this around, but my experience has showed it is not very long.
When feeder, camera and background are in place, the camera needs to be focused on the feeder port in manual focus mode. The aperture will provide sufficient Depth of Field to assure the bird is sharply focused. As things are moving around, especially in a breeze, auto-focus tends to continuously hunt for a target. The picture you are trying to achieve, depending on lens focal length is like the one below. As the hummer sips, it will back away and then return to the feeder. When it backs away is the opportune moment to shoot.
Finally, the last thing to do is process the image. I shoot in RAW, so I can achieve excellent white balance and tone values in blacks, whites, shadows, highlights and mid-tones. Adobe Camera Raw is the perfect solution for the processing. Other software packages are available including, Lightroom, and On1. After processing, a final crop will yield excellent compositions.
Later, as your success rate increases, the set may be fine-tuned by the addition of a couple of strategically-placed flowers and greenery to hide the feeder and to provide a framing device for the composition. In addition, the hummers may enjoy actually feeding from several species of tubular flowers with a bit of sugar-water mix in the flower throats. Watch the vegetation the hummers actually use and select some blossoms and greenery for a natural set-up. Then get your finger on the trigger and enjoy!

Many times when producing images of small subjects we find that there is insufficient Depth of Field (or depth of Focus) to render the entire subject sharply from front to back. Insufficient Depth of Field (DoF) is cause by three factors:
First, we understand that, in addition to exposure, aperture controls DoF. As we increase the F number we add DoF. However we may not be able to make a good exposure with a big F number like F22.
Another factor is that as we increase the focal length of our lens, the DoF becomes smaller. We could select a shorter lens, but that changes perspective and ability to focus close in the case of a macro lens.
The final consideration is that when the lens is moved closer, the DoF also becomes smaller. Thus we are our best enemy and must deal with self-imposed photographic criteria.
Therefore we have learned to use focus stacking to solve this problem. This requires a series of often many images, each made at a different point of focus from front-to-back. The images are blended into on in the computer using specialized software. The image of the bee (below) is an example of a stacked composite of 50 blended images.
The several images are captured using different points of focus. Some lenses change magnification as the focus is changes, creating alignment problems. The better approach requires moving the camera a measured increment between shots. A geared focusing rail (below) or an automated programmed focusing rail are specialized tools for changing the focal point without compromising image size.
Another system uses a rail incorporated into a bellows system to change focus but not scale, as pictured below. There are several choices from several manufacturers to accomplish this movement process.
Now comes the new tool on the market- The Helicon FB Tube. This new idea comes from the producers of Helicon Focus, the industry leader in image stacking software. Essentially it is an extension tube with integrated electronic micro-controller designed to enable automated focus bracketing in single or continuous shooting modes. The measured tube length is 13mm and adds somewhat to the magnification of the lens dependent upon the focal length. Mounted on the camera in the same way as a usual macro extension tube, Helicon FB Tube automatically shifts the focus by one step with each shot thus producing a stack of images of unlimited length that can be rendered into a fully-focused image.
Helicon FB Tube needs no additional hardware apart from conventional cameras and lenses. Helicon FB Tube has no optics and does not affect image quality. Helicon FB Tube settings are configured through an additional application for Android or iOS. The set contains: Helicon FB Tube with IR Receiver and LED Indicator; Front and Rear Caps; IR Transmitter – connects audio port of a smartphone and Extension cable for smartphone and IR Transmitter.
The unit has been tested and found compatible with a wide number of camera models and lens. Helicon FB Tube is available with mounts for Nikon and Canon cameras and AF lenses with built-in motor.
I tested the image focusing ability of the FB Tube making 15 focus step images of the acorns below using a step factor of 70. The camera was a Nikon D800 with the FB Tube and 105mm F2.8 Micro Nikkor. Selected aperture was F5.6. Electronic flash in TTL Mode within a softbox provided consistent light.
To set up the FB Tube a couple of simple settings are made on the smartphone device, including lens focal length, crop factor, aperture and step size. this was relatively straight-forward on my iPhone using the available ap:
The phone then transmitted the data to the FB Tube via an IR emitter plugged into the phone audio jack and aimed at the tubes receiver. as shown below.
To get started, the first focal point was focused manually at 3.0 CM on the rule. The rest of the images in the series were focused automatically by the FB Tube. Three of those images are shown below -the first, middle, and last- of the 15 image sequence.
The fifteen images were selected in the computer and rendered in Helicon Focus
Method B (depth map) in a normal manner, rendering sharp focus from front to back. Final adjustments for tone, color and sharpening was completed in Photoshop CC.
There are several procedures to make images for stacking. Moving the camera is simple and inexpensive. A manual rail is a bit of an expense, Fully automated, servo motor driven rails and associated accessories are often more than $600. In comparison, the Helicon FB Tube costs $200.
