Sometimes It Just All Comes Together

Gorillas have always been a difficult subject to photograph. They're nearly black making it a challenge to retain any detail in their faces. You simply cannot photograph them well in direct sunlight, you need them to be in even shade and preferably on an overcast day. In captivity there are few enclosures with a natural green background.

It all came together for me the other day with an opportunity that lasted for just a few seconds. This is an endangered Western lowland gorilla male silverback with a prominent sagittal crest.

High Speed Strobe Synch

2011-03-10T11:36:00.000-08:00

It's been nearly a year since we last photographed these Burrowing owls. Therisa learned something new that still has me shaking my head in disbelief, High Speed Strobe Synch! With our Canon 430 EX Speedlite we can enable High Speed Synch and synch higher than 1/250 sec. We can strobe synch at any shutter speed! Wow, where have I been.? What a plus this is for moving subjects and being able to utilize faster shutter speeds with long lenses.

With this in mind we set out to photograph the diminutive Burrowing owls, knowing that we needed to get lower and closer. It's frustrating to have good tripods that still don't go low enough. Bean bags to the rescue!

Lighting Zoo and Aquarium Exhibits

2010-11-01T09:45:00.000-07:00

This Electric eel, Electrophorus electricus, was photographed with a 10-22mm. Canon lens at 22mm. More photos can be viewed here.

Many people have asked me over the years how I shoot indoor zoo and aquarium exhibits.

Lately I've seen photo submissions from aspiring photographers who have simply tried to take advantage of improved noise reduction in the current crop of Digital SLR cameras while pushing their camera's ISO into unacceptable realms. I'm afraid 3200 ISO is not going to be acceptable to any photo editor, art director or photo agency unless you've captured something that no one else can duplicate. In short, I am a firm believer of keeping your ISO at your camera's lowest possible setting.

To light indoor zoo and aquarium exhibits use a strobe. Yes, you can use the pop-up strobe built into your camera. In this case I used the Canon 430EX Speedlight, set to TTL, mounted on the camera's hot shoe with a diffuser. In either case I shoot in Manual mode, usually with the shutter speed set at it's maximum synch speed (1/250 sec in this case) to eliminate the unwanted color temperatures of the exhibit's artifical lighting sources. The lens aperture will usually be the smallest f stop (in this case f 13) in can get for the light output with the diffuser on. Your camera's LCD will give you exposure feedback in each situation. If your image is too dark at f16 (underexposed), open up the aperture. If your image is too light (overexposed), close down the aperture. Pretty soon, you'll be getting the repeat experience you need so you can dial in the f stop quickly.

The other trick to avoid reflections is to make sure your lens is touching the exhibit glass. If you have a subject really close to the glass, you still can shoot it if you get your strobe off the camera on a TTL cord to the hot shoe or by using a wireless TTL strobe trigger.

Testing New HDR Software

2010-10-17T13:18:00.000-07:00

Just downloaded Nik HDR EFX PRO software for a free 15 day trial. This image was from my very first test drive. I'm impressed. You will not believe the amount of control you have over the image output with their "U Point" feature:

with "U Point^® technology, you can make precise selections to easily fine-tune and enhance specific areas of your image."

Different Perspectives

2010-08-12T05:27:00.000-07:00

To capture what remains of the Key West shrimp fleet at first light, we set our alarm clock for 4:00 A.M. and drove the 90 miles south in darkness. We had a good idea where to find the old shrimpers as we had done our homework even utilizing Google Map's satellite imagery.

Arriving in dim pre-dawn light, we located the rusting boats and grabbed our camera gear. I opted for the Canon 10-22mm while Therisa took off in the other direction with the Canon 100mm. Soft first light draped the shrimp boats. 30 minutes later the best light was gone but we each had our images. It was fascinating to see our different perspectives on the same subject, proving to us once again the importance of our teamwork.

Granddaughters In The Pool

Once in awhile it's simply good to get out of your comfort zone and try something new, with the helpful cooperation of two of our beautiful granddaughters.

These Owls Have An Attitude!

2010-05-21T11:31:00.000-07:00

Burrowing Owls (Athene cunicularia) are amazing to observe and photograph. What does it take to get these shots? First and foremost, respect for the wildlife. Never pressure the animal to get the shot. With that in mind it takes a lot of patience while crawling on all fours and laying flat on our tummies looking through a long telephoto lens mounted on a tripod. We learned much from our first attempt and plan to return soon hoping to capture the fledglings emerging from their burrow.

Coral Restoration Photo Assignment

2010-05-10T07:04:00.000-07:00

Background image on the opening page above is by our photographer David Fleetham

Our photo assignment on Coral Restoration for National Wildlife Federation's Ranger Rick magazine, May, 2010 issue. While we had photographed this on assignment for another magazine a couple of years ago, this time was very special as it involved young divers harvesting endangered staghorn coral from an underwater nursery and transplanting the coral to a damaged reef site. This is, without a doubt, the most gratifying photo assignment we've ever worked on from the standpoint of subject matter. Our editor and staff at Ranger Rick magazine, once again proved to be the absolute best to work with! For more information see: www.coralrestoration.org

Perspective

2010-03-20T05:09:00.000-07:00

Prop roots of a Red Mangrove (Rhizophora mangle) at low tide, Key Largo, Florida.

We are constantly challenged to create unique images.

How can you make your photography stand out in the crowd? A fresh perspective on a common subject sometimes does the trick.

In this case, instead of laying down in the wet low tidal zone, I lowered the camera to the ground and without even looking through the viewfinder shot a series of images with the Canon 10-22 lens at 10mm. hoping to get some relatively straight horizon lines which I could crop straight.

Daybreak Fun

2010-03-16T09:09:00.000-07:00

We live on a small island (Plantation Key, Florida) and we keep scouting for new locations.

It's quite a challenge, as most of the waterfront land is privately owned and inaccessible.

We found this site a few weeks ago and thought we would give it a try this morning.

Shooting An Earth Science Textbook Cover in Florida?

2010-01-25T11:03:00.000-08:00

5:00 A.M. alarm clock wakens us to a 65 mile drive south through several rain downpours in the predawn darkness. Thirty minutes before sunrise we arrive at our destination: the bare, weather eroded limestone that is the remnant of a fossilized coral reef. Low tide is on our side, the 20 knot wind is not. We get to work cautiously scouting locations on the slick rock among the tide pools. A wonderful red mangrove will make a fantastic backdrop, but we realize that HDR isn't possible in this wind. We photograph it anyway, knowing we can utilize some digital post processing magic to make the image work. Thirty minutes later, it's over and we've captured nearly 1 GB of camera RAW images. Black coffee tastes really good!

The impetus for this photo journey? For their Florida Adoption a textbook publisher needs a Florida location with obvious Geology for an Earth Science textbook. This photo need has plagued them for weeks. Florida is not a state known for dramatic geological features.

P.S. The mangrove photo is a "manual" HDR made from two frames, one 2 stops underexposed and the other 2 stops overexposed, combined in Photoshop, then processed through Photomatix

We shot both vertical and horizontal as we were told there was a possibility of a wrap around cover.

Horizontal and Vertical

2010-01-03T04:58:00.000-08:00

A couple more shots from New Year's morning shoot at Everglades National Park.

I absolutely love creating images like these. Unfortunately years of photo marketing experience has taught me that there is not much sales potential for these in the world of publishing. Fine art prints? Perhaps, but we don't deal in that realm much.

Whatever. Sometimes it feels absolutely wonderful shooting creatively instead of constantly being concerned about "what sells". Nevertheless, I did learn a long time ago to work a subject both horizontally and vertically, always forcing myself to recompose in the viewfinder before walking away.

So even if shooting these for enjoyment, I'm no fool. I cover my arse and compose several verticals as well.

Covers photo sales pay more.

New Year's Morning

2010-01-02T10:55:00.000-08:00

We've long held a New Year's Day tradition, photographing a location in Everglades National Park at daybreak. It's wonderful as we set our alarm for 4:30 AM and depart at 5:00 AM. There's no one on the roads and we have Everglades National Park nearly to ourselves. This was taken at dawn, January 1, 2010 near the Long Pine Key campground area.

Mangroves

2009-10-18T09:34:00.000-07:00

We've been hard at work on a Mangrove assignment and in so doing have learned much about these fascinating plants.

Top photo: Red Mangrove flowers, Rhizophora mangle, flowers are either self pollinated or wind pollinated and less than one inch in diameter.

Second Photo: Propagules of Red Mangrove, Rhizophora mangle. When ripe, these young seedlings detach from the parent tree and float in the Florida Bay until a suitable substratum is contacted.

Third Photo: Underwater view of the Prop Roots of Red Mangrove, Rhizophora mangle, which serve as a host for algae, sponges and other marine life.

Yet Another Reason Why Photography Is Wonderful

2009-10-12T12:05:00.000-07:00

Therisa found this amazing creature in our yard the other day!

After doing a little research with the help of knowledgeable friends,

she was determined to be a female Florida Bagworm (moth),

Oiketicus abbotii, female in sack.

This is the only bagworm species in the U.S. that arranges twig pieces transversely.

Changing A Frog's Diaper

2009-09-14T10:47:00.000-07:00

Four of our frog photos are being used in the 2010 World Wildlife Federation's "Frogs" calendar.

Seeing these gorgeous rainforest amphibians in sample calendars we received the other day brought back fond memories of six large terrariums on our dining room table for several months. Each was filled with rocks, stones and large amounts of sphagnum moss and served as homes for our amphibian models who were not exactly low maintenance creatures. In addition to maintaining proper temperature and diet, the moss needed to be removed, rinsed and cleaned by hand on a daily basis. We called it "Changing the Frog's Diaper!"

Photo Sales For Advertising Use Pay The Bills

2009-08-20T09:00:00.000-07:00

The bottom photo of the dive flag at sunset had been used in both print and trade show advertising for the Monroe County (Florida Keys) Tourist Development Council annually for three years.

Image our surprise and delight when their advertising agency contacted us once again to negotiate pricing for its new use in a print ad, top photo.

The fee we agreed upon is 10X higher than what we would have been paid for the editorial use of this image in the same magazine at the same reproduction size.

The message is clear, photos used for advertising pay the bills, take no prisoners!

Young Stewards of the Ocean

2009-08-06T07:56:00.000-07:00

We just completed a a wonderful photo assignment for National Wildlife Federation about young people involved in staghorn coral restoration. We photographed these young divers as they harvested the coral from an underwater nursery, cleaned the growth bases, tagged and measured the corals. Surfacing with their selected corals we then traveled to a damaged area on a nearby reef where we photographed the boys and girls using a special underwater epoxy to "plant" the corals on the reef.

Since our contract dictates we cannot release the photos until they are published by National Wildlife Federation, the photos shown here are of another coral restoration event involving college students that we photographed on assignment for a magazine in 2007.

It's really gratifying to work on an assignment about such a positive project!

Life on Mars

2009-08-03T11:03:00.000-07:00

Sometimes you just can't sleep at night. You've got this idea, this concept and you know there will be no rest until you breathe life into it. Creativity is like that. Fortunately I have a wonderful wife who feels the same and we often work together, as we did here on Mars, to make an idea a reality.

Fossil Shooting Out West

2009-07-31T10:27:00.000-07:00

Therisa and I learned long ago that the key to survival in the highly competitive world of photography is to shoot "niche" subject matter. These are subjects that not everyone photographs so that when a photo editor is, for instance, searching for an image of a fossil snake, we should not face an avalanche of competition. We plan our photo journeys accordingly and are both well tuned into locating unusual subject matter in advance.

The fossil snake above was discovered in 2007 and only the second fossil snake from the Green River Formation in Wyoming. Preliminary identification suggests it's a boa.
