High-speed Flash Hummingbird Photo Workshop

 

Hummingbird action at the recent High-speed Flash Photo Workshop captivated and challenged the participant photographers during the morning photography workshop.  -Bert Garcia

 

Filled with early morning German strudel warm from the bakery, seven photographers met in Fredericksburg, Texas, eager to learn how to photograph hummingbirds with high-speed electronic flash.

After a fifteen-minute drive west of town, the group gathered at a private ranch that has a lot of hummingbird action spread among many established nectar feeders and native vegetation.

Upon arrival, the group was instructed on details of the setup and reviewed camera settings previously provided in a written brief. The group then set about to place flashes, triggers and backgrounds for three photographic positions. All feeders were removed except one at each photographic set-up. Even as the setups were refined the birds began working the nectar feeders.

All the holes of the feeders were taped over except one. This process provides a predictable path for the birds’ approach.

 

Each photographer had a shooting station complete with a nectar feeder, two flashes for the bird, a large printed background and a flash to illuminate the background. The tripod-mounted camera was equipped with a Pocket Wizard radio trigger to activate each flash in synchronization.

Throughout the morning shoot, the images were evaluated in-camera and the settings and positioning were tweaked for optimum results. All participants were excited over the images they capered as they reviewed the shoot on the camera displays. Many of those images are found here:

South Texas Bird Photo Workshop Update

The South Texas heat did not stop workshop participants from getting some exciting images of Spring birds during my latest Bird Photography Workshop at Laguna Seca Ranch.

Held during the last week of May, the workshop featured three days of photography at water features in morning and afternoons. Additionally, a morning dedicated to raptor photography provided many photo opportunities.

Great Crested Flycatcher -Dolph McCranie

 

Laguna Seca Ranch is located in Hidalgo County deep in Texas’ Rio Grande Valley.  It is predominantly South Texas chaparral, featuring mixed grasslands interspersed with Mesquite, Ebony, and Hackberry mottes. Due to the climate, numerous specialty species abound and during this time, migrants return from Mexico and Central America.

Male and female Northern Cardinal pair interacting with food. Bird interaction is always nice in a photograph. -Cathey Roberts

In the afternoon, the temperatures reached the century mark. It was quite hot for photographers, but the temps also brought the birds to the water features to bathe and drink. That is an added benefit of the water features.

The water feature attracts many avian species, especially when it’s hot, including this Scissor-tailed Flycatcher. -Brian Loflin

Another favorite at the water feature is this Greater Roadrunner getting a drink. -Brian Loflin

The colorful male Pyrrhuloxia is a member of the cardinal family and is generally the western member of the family -Brian Loflin

Northern Bobwhites were paired up prior to breeding. Many good images were made of these birds. -Cathey Roberts

 

The noisy, ever-present Green Jay is a South Texas Specialty species, highly sought after by birders everywhere. -Dolph McCranie.

Big Bend Landscapes, Light Painting and Starry Night Skies

Over the last weekend in February 2020, Shirley and I led a workshop to the Big Bend area of Texas. Our goal was to specialize in capturing images of the many striking landscapes, and historical spots in the area and to teach some techniques of light painting and star photography.

Eight photographers from across Texas joined us in Study Butte and photographed for four days. We had early mornings most days and late nights for a few. To make a 7:30 AM sunrise photograph at Santa Elena Canyon requires a 6:00 AM departure from the hotel to make the road trip in time to set up properly.

Photographers are very much aware of the vast difference that a few minutes can make in the color of any given scene as evidenced by this image of the sunrise at Santa Elena canyon- just five minutes apart.

Spectacular sunrise at the same spot -Art Madden

Early morning light within the first hour of the day is the perfect time for Santa Elena Canyon. During this time the 1,000 foot canyon walls are illuminated brightly by the warm morning rays.

During the four days we had a planned itinerary that took us virtually from one end of Big Bend National Park to the other, including Terlingua (TX) Ghost Town and Cemetery and much more.

Big Bend is full of varied wildlife including an extreme number of bird species.
Roadrunner -Art Madden; Whitewing Dove -Alan Lusk.

Thousands of people flock to Texas to see the amazing spring wildflower displays. Bluebonnets are the most recognized species. In Big Bend, the Blue bonnets are a different variety, tall and lanky, but impressive nonetheless. – Alan Lusk

No desert photography trip is complete without cacti. This prickly pear, Spiny-fruited Prickly Pear (Opuntia spinosibacca), is one of this author’s favorite. -Art Madden

For most days the weather was nice, the sunlight cooperative, but the only disappointment was cloudy skies each night preventing star photography.

 

By the end of the trip everyone had captured thousands of great images of this most interesting countryside.

Backing up Digital Image Files

What is backing up digital files?

Digital photograph files are a non-tangible entity, a digital data file, living insecurely in the ether of ones and zeros in a computer storage system. No longer do we have a shoe box or file drawer of negatives, prints or color slides. Therefore, we must house our files in a place that is easy to access, readily retrievable, and safe.

Tangible photographs, including negatives, prints and slides are no longer a part of digital photography. Shoe boxes and file drawers full of photos are a thing of the past. Today. we must safely store digital image files where they may be organized, accessed and protected. Such is just one job of today’s digital photographer.

 

To achieve a storage system that meets these criteria requires some thought, planning, and a bit of monetary outlay.

Today’s planners and designers of most modern computer operating systems do not do the serious photographer any favors. Operating systems like Windows, and Apple iOS are designed around the principle of a single computer operating system drive whether a hard, spinning disk drive (HDD), or a solid-state drive (SSD), or a hybrid of both, like a fusion drive.

We must understand these components are electronic, some with mechanical components. Within the computer system, the drive with the operating system is operating full time when the computer is turned on. Electro-mechanical drives are spinning all the time. It’s understandable that these components will fail. Solid-state SSDs are vulnerable to component failure by detrimental heat.

Failure will happen. It’s not if — but when.

So, if all our photographs are on our computers operating system (op-sys) drive, and we have only one –like most photo enthusiasts– our images will be lost with the failed drive. Therefore, we must put our photographic images some where else that is safe. That’s the first step. The second step is even more important, that is making a duplicate of every photo in a second place for safety through redundancy. That’s backing up!

In an ideal situation, the op-sys drive should contain only the operating system itself plus other software such as the photo editing software and so on. Everything else including, photos, financial and medical files and all other personal files must be kept elsewhere.

There are several ways to do this. Some photographers have multiple drives installed within their computer cabinet. This is a good idea at the time of computer purchase, or at the time of its assembly. This generally requires a larger case or cabinet and lots of fans to move air for cooling- the detrimental foe of electronics. Given the physical space and electronic capability, additional drives may be added at a later time.

The use of additional drives requires not only initial planning for installation, but a serious thought toward file organization. This is food for a later discussion.

The alternative plan used most frequently is the use of external electronic drives, or portable drives. Today, these drives have become very inexpensive and create a low-cost solution to the storage issue. Let’s look at common solutions:

JBOD- Just a Bunch Of Drives

As an addition or addition to internal drives installed in the computer cabinet, external electronic drives are now very inexpensive and are available as spinning hard drives, or solid-state units. Capacities are now available in 1TB, 2TB, for pennies compared to the past, and larger capacity drives don’t cost much more. Today the HDD drive is the low-cost choice of the two and the SSD drive, the most reliable over time.

Several electronic portable drives are a simple, cost effective manner of storing images off of the computer operating system drive. Over time, the file data may grow quite large. Organizing and securing the data is a more complicated task when using such a bunch of drives.

 

In operation, these additional drives are connected to the computer via a variety of methods, including USB, Firewire, or Thunderbolt. Regardless, the computer will recognize these external drives and data files may be moved to them readily.

Some manufacturers offer drive systems that enable expansion as required. The three drives above are tied together in JBOD system. But, management of file storage and redundancy is a continuing issue.

 

In this manner, the JBOD requires manual moving, saving, and management of file material. To create any type of redundant protection, all the data on one file must be completely duplicated on a frequent basis to a second drive.

With personal dedication and commitment, this is a most workable, inexpensive solution.

RAID- Redundant Array of Independent Disks

A RAID solution takes the JBOD solution one major step further. Most frequently, a RAID consists of two or more physical drives housed within a single enclosure and it automatically creates the duplication of data and back up continuously as it is used. The computer “sees” the drives as one and operates as such. Management of storage and duplication of data is accomplished by the electronic RAID controller within the system enclosure.

The three units pictured above are a RAID system. Each box contains two independent drives, with an electronic controller. It provides a seamless, user-friendly method of safely backing up the images through redundancy. The process is managed by the internal RAID controller. Each unit is a 20TB RAID. When used together, the system will store 60TB of data, providing 30TB of file storage with an equal amount of redundant backup.

 

In such a system, disks are combined into different RAID configurations known as RAID levels. The RAID level you choose depends on which storage attributes are most important to you, including:

Capacity-               The total amount of data you can store.
Performance-        The speed at which data is copied.
Protection-             The number of disks that can fail before data is lost.

RAID 0—Data is not duplicated on both hard drives in RAID 0. This results in faster transfers and more storage, since the full capacity of both drives can be used to store unique data. However, RAID 0 lacks a very important feature: data protection. If a hard drive fails, all data in the array is lost.

RAID 1—RAID 1 provides greater safety since data is duplicated on each disk in the array. If a single disk fails, the data remains available on the other disk. However, this comes at a cost -since the same data is written to each drive, copying data takes longer and overall storage capacity is reduced by 50%. RAID 1 is a good choice when safety is more important than speed or disk space. It is the best solution for photographers requiring redundancy AND security.

Remember: Always eject a storage drive from your computer before physically disconnecting it. Your computer must perform filing and housekeeping operations on the drive before it is removed. Therefore, if you unplug the drive without using the operating system’s software, your files can become corrupt or damaged.

NAS (Network Attached Storage)

NAS is a storage system device that connects to your home or office network and can include one or more hard drives. A NAS is engineered to be a single drive, JBOD, or RAID systems. Unlike direct, hard wired solutions, files on the NAS can be accessed using a computer, tablet, or smartphone that is connected to your local network or even over the Internet. Many systems offer an intuitive and user-friendly NAS experience while offering tons of rich applications, allowing you to share files and enjoy multimedia anytime.

CLOUD Storage

Online, or Cloud storage is now a viable option for independent photographers. This system requires the upload of digital files to an online, commercial site for storage and retrieval. To commit to a cloud-based solution, keep in mind several considerations:

Internet speed and reliability– how long does it take to upload and access your files
Cost of internet service– are you charged a premium for high use
Frequency of use– do you need the service all day, every day
Type of files stored– are you storing only JPGs or RAW files and complete projects

After a review of the above, you may find cloud storage may not be a good fit for you. Some plans are good for small amounts of data (images) but if you shoot in RAW and have thousands of images, some plans can’t cut the mustard.

If you do feel the Cloud is right for you make certain you carefully consider the following before you commit:

Have a Plan with Three Backups (see the 3-2-1 Backup plan below.)
In addition to your master working files, have at least one Local Backup

Have an Off -Site Solution
Use a multiple hard drive system
Use on-line Cloud storage only as part of your strategy
Don’t rely on the Cloud as your primary or only backup

The Cloud may not be reliable
Internet goes down
Servers get hacked
Fees are late or don’t get paid
Terms change without notice
Cloud companies go out of business or are acquired by others

Minimum Acceptable Usage Scenario
Consider 1TB of RAW files as minimum capacity- (Some plans don’t support RAW)
Fast broadband connection- No Dial-Up or Wi-Fi
No metered web usage from your service provider
Fast service Up / Down Speed
Works with either Mac or Windows.

The 3-2-1 backup plan

Serious photographers who are conscientious about their work carefully store, safeguard, and backup all their images. As we have seen, there are several ways to do this and additional variations on each system. Regardless of the system that is used, you should have a thoughtful plan in place that will provide you the comfort in the safety of your work and your legacy. A workable plan is outlined below:

1. Have at least 3 copies of your data
   Having three copies of data means that the first one would be your actual data, wherever they reside. The other replicas (redundant clones, or mirror images) will provide for high availability and redundancy, since the more replicas you have, the more chances to keep the data safe.
2. Keep these backups on 2 different media
   You should keep the data in two different formats, for one format outlives the other. For example, disks from the same RAID are statistically dependent, and often, after one disk failure, you might experience the failure of another disk from the same storage in a short period (often because the devices are of the same age). Using different formats reduces the risks that all your backups will be damaged, as different formats have different strengths and weaknesses when it comes to redundancy.
3. Store 1 backup offsite
   It is understandable that a big disaster like an earthquake, fire or another unpleasant event will destroy buildings, and even data centers may burn down resulting in powerful data loss. It is the reason why considering offsite data backups comes into view.
   Offsite means as FAR AWAY as possible, in another city, state, country or even continent. Your data is safe then, even if there is a fire or national disaster.

There are many ways and solutions to accomplish this 3-aspect task, be they software or hardware. Backup process should be set as far from manual interaction as possible to avoid human error. It is highly recommended to run backup jobs on a regular basis and scale (weekly, monthly backups, etc.) to be able to restore from the most recent and consistent one.

South Texas Bird Workshop – May 2019

May begins a traditionally long hot, and often humid, season in far south Texas. This year is no exception. However many copious rains in April have kept the countryside lush and green. This has been a blessing for bird life.

This workshop during the last week of May was very productive with a large variety of great birds. Frequently in pairs, the species photographed numbered thirty-one, including some favorites including Painted Bunting, Summer Tanager, Blue Grosbeak and Grove-bill Ani. The traditional South Texas favorites included Green Jay, Pyrrhuloxia, Great Kiskadee, both Long- and Curve-bill Thrasher, Golden-fronted Woodpecker, Olive Sparrow and many more.

The following represents just a few of the favorites.

.From the top left:Painted Bunting female, Painted Bunting male, Painted Bunting first year male, Blue Grosbeak, Summer Tanager male, Couch’s Kingbird, Grove-bill Ani, Green Jay, Curve-bill Thrasher, Mature and immature Crested Caracara, Crested Caracara Portrait with mouse, Greater roadrunner with mouse, Greater Roadrunner, Pyrrhuloxia, and Long.bill Thrasher.

Everyone was able to make many amazing and similar images to take home. And the camaraderie was top notch.

If you have interest in a similar workshop, the next one is scheduled for October 24-27. 2019. If you have interest visit my web site at The Nature Connection or send me an email to bkloflin@austin.rr.com.

Two Stories: Extirpation vs. Restoration

 

Fossil fish, possibly of the extinct genus Knightia, which is only about seven inches long. This is typical of the fossil fish that are found in shale and limestone strata. Complete fish tend to be rare, and it is far more common to find just parts of fish, like the backbone with ribs and spines attached shown above, which came from sedimentary layers of the Eocene period about 55 million years ago.

 

The National Geographic Channel is currently airing a television series called One Strange Rock. The program talks about the history of life on earth and five mass extinctions on the planet [Earth]. In the series, host Will Smith narrated, “Ninety-nine-point nine percent of all species that ever lived are gone.”

That statement refers to all the dinosaurs and all the animals and plants of the fossil record. That’s in the past, for sure. But you must be certain, this process of loss continues even today. Let’s look:

Extirpation:
Sandbur prickly pear cactus, Opuntia Pusilla

Long, prostrate chains of elongated pads are typical of Opuntia pusilla. These pads are easily detached, making the plant typically quite short.

 

During the field work and production of our 2009 book, Texas Cacti, I was elated to be able to find a little-known cactus, Sandbur prickly pear. This species is recorded to be found only in a small area on sand dunes and rocky outcrops, behind the beaches along the Gulf Coast only on Bolivar Peninsula in Galveston County, Texas.

Detail of Opuntia pusilla pads, or stems. These stems are usually low and are seldom more than 4 in.  (10 cm.) tall.

 

Making landfall over Galveston and the Bolivar Peninsula in Texas at 2:10 a.m. on September 13, 2008, a category 2 hurricane named Ike caused extensive damage, with sustained winds of 110 mph, a 22 ft storm surge, and widespread coastal flooding.

The effects of Hurricane Ike in Texas were crippling and long-lasting. Ike’s effects included deaths, widespread damage, smashing and flooding an estimated 100,000 homes. Galveston was declared uninhabitable, and the Bolivar Peninsula wiped clean of boats, buildings and most vegetation.

Aerial photograph of the Bolivar Peninsula at Galveston Texas the day after Ike. The 2008 hurricane Ike wiped most all vegetation and structures from this area.

 

After several visits to the Bolivar Peninsula after Ike, we are very disappointed to to be unable to find any remaining indications of this little plant of the species.

Restoration:
Tobusch Fishhook Cactus; Sclerocactus brevihamatus var. tobuschii

Endangered Sclerocactus brevihamatus var. tobuschii is quite cryptic in its growth among the grasses of its habitat. Often pollinating bees may lead us to the flowers in season.

 

The endangered Tobusch fishhook cactus, named for its unique hooked central spines, is found in only eight counties on the Edwards Plateau in central Texas. This uncommon cactus spends the first five years of its life smaller than the size of a quarter before even producing its first flowers. This cactus is a low, deep-seated and very inconspicuous plant because of its diminutive size, and the fact it is camouflaged within the grass and limestone of its habitat. Therefore, it very difficult to find.

During the production of our same publication, I was thrilled to be shown a small population in Kerr County, Texas by Jackie Pool, a biologist from Texas Parks and Wildlife who monitors this critically endangered species.

Inconspicuous funnel-form, greenish flowers are about one half of an inch in size and bloom in February and March. The hooked central spines give rise to this plants common name.

 

 

Tobusch fishhook cactus was classified as an endangered species in 1979, when scientists knew of less than 200 plants in the wild. At the time of my photos there were just over 2,000 plants identified. Today, numbers have since improved through the discovery of additional populations, research on threats, conservation efforts at documented sites, and teamwork between a host of partners including the U.S. Fish and Wildlife Service, Texas Parks and Wildlife Department, private landowners and many more.

Now, approximately 4,500 cacti are known to exist across the species’ range. In big news for a little plant, the Tobusch fishhook cactus’ federal conservation status was this week reclassified from endangered to threatened under the Endangered Species Act as of June 14, 2018.

I have been honored to get to know this little cactus in the wild, to photograph the little plants, and to watch its recovery.

Change continues. Today there are reported to be over 1.7 million species of plants and animals described by science. And new ones are discovered every day. And, of course, we know nothing of the species yet to be discovered. Only time will tell.

Close up lens selection for larger insects

Roseate Skimmer Dragonfly, Orthemis ferruginea (m)-
Nikkor AF 200 mm F 4.0 Micro Nikkor lens. Fill flash.

 

Last week I was preparing to visit one of my favorite hunting grounds for insects and other critters. The nearby Hill Country Water Gardens is an amazing emporium catering to those who build and maintain ponds. Additionally, they are a very complete nursery with a wide variety of plants. The best thing for me is that they have many tanks and ponds with live water lilies and lotuses. These water features attract many varieties of aquatic insects, including dragonflies and damselflies.

As I was gathering equipment I was selecting the optics appropriate for the day. I knew that I needed more reach than standard macro lenses like my Nikon AF 60mm F 2.8 Macro Nikkor or my Nikon AF 105 mm F2.8 Macro Nikkor. These two lenses are great, but the magnification just is not enough. My longer, Nikon AF 200mm F 4.0 has more reach, but as a fixed lens, there is no angle of view versatility and it will not accept a teleconverter.

So, the tried-and-true solution is a mid-range telephoto lens, with the addition of a teleconverter and for close-focusing ability the addition of a short extension tube. Frequently, a prime lens like a 300 mm lens with a 1.4x or 1.5x teleconverter and a 10 to 25 mm extension tube works well. The arrangement allows a full frame sensor to produce a field of view of about 4 inches and will focus to about 2 feet. That’s perfect, but that arrangement still has no angle of view flexibility.

The answer lies with a zoom telephoto lens, a teleconverter, and if required, an extension tube. With a teleconverter and extension tube robbing the optics of light, a fast lens is most desirable. The solution is a Nikon AF 70-200 mm F 2.8 VR Nikkor lens. To it we add a TC-17EII AF-S teleconverter. This produces a focal length range from 119 to 340 mm and at 200 mm, a field of view of 3.5 inches wide on a full frame sensor. The good thing about this arrangement is that it will focus down to 3.6 feet (measured from the sensor- about 2.5 feet from the front of the lens), plenty close for dragonflies and similar insects.

Canon makes the same arrangement with a 1.4x and a 1.5x teleconverter as well as a 2.0x. Their 70-200 F 2.8 lens will focus to 3.94 feet with a similar set up.

Both Nikon and Canon produce F4.0 versions of these two great lenses at a considerable difference in price.

Robber Fly, Efferia albibarbis (m)

As these minimum focusing distances are perfectly ideal for butterflies, dragonflies, damselflies, and other insects and creatures, there is no need for an extension tube. A 12 mm extension tube will produce a 3.0-inch field of view but will further reduce the effective aperture by an additional stop. In some cases, you need all the light you can get for best auto-focusing and low light situations.

Another benefit of not using the extension tube is the lens combination can focus to infinity. This is a great benefit for that surprise bird or other subject at greater distances.

As in all outdoor photography, a flash used as a fill flash about 1.0 EV below the ambient exposure helps produce images with lower contrast, higher dynamic range and with more motion stopping capability. All the images in this article, except the lilies,  were produced with a Nikon SB-910 Speedlight at minus 1.0 EV.
