American Toad_9913

The two images presented here were created a few seconds apart. Often I will take several images from various angles and perspectives when photographing frogs and toads at night, especially when I see the ripple effect. The ripple effect is created when the toad’s vocal sac touches the water’s surface while it is chorusing. The vibration of the vocal sac creates the ripples. In each of these images I was immediately drawn to the way the dead cattail leaves were framing the toad along the bottom portion of the composition and while composing I made certain not to cut-off the ‘V’ created by the break in the leaf at the bottom edge.

Gray Treefrog_244

A few nights ago I ventured out into a new pond that I had discovered where Gray Treefrogs are chorusing very loudly. The pond already has a dense growth of cattails so working my way out to the area of the pond where the frogs were located was tricky at best, but I was able to create a few new images that ended up in the keeper file :) Gray Treefrogs are the chameleons of the amphibian world, able to change their colors to blend in to their surrounding environment. Photographing them in the spring when they are at their breeding pools among the green cattails typically produces images of them in their splendid greens.

Green Frog With Vocal Sac Inflated

Green Frog With Vocal Sac Inflated

By far the most productive nights for photographing frogs and toads tend to be those which are humid, rainy, or drizzly. Above is a recent Green Frog photographed with its vocal sac inflated that was created on a wet evening after the rain stopped. Using a Nikon D800 and a Nikon 105mm Micro lens, I knelt down in the shallow pond with my chest waders on and assumed a low and steady perspective  by resting my elbows on the pond’s substrate. Green Frog’s vocal sacs are only inflated for a brief period while they are making their loose banjo string-like song, but closely watching their movements you can easily learn when to press the shutter to capture a fully inflated vocal sac.

A Large Male Bullfrog on Horseshoe Lake, Parry Sound, Ontario

A Large Male Bullfrog on Horseshoe Lake, Parry Sound, Ontario

I created this bullfrog portrait last summer on Horseshoe Lake near Parry Sound, Ontario. The easiest way to create such images of bullfrogs is to do so from a canoe. Bullfrogs are generally quite approachable and will often tolerate you sliding up beside them in a canoe. By using the Live View mode on my Nikon D800 with a Nikon 105mm Micro lens attached I was able to hand-hold the rig just above the water’s surface for a low perspective – the lens hood was actually dipping into the water slightly. When you photograph frogs in the water from such low perspectives you will be able to get the accompanying reflection. To ensure that I am holding the camera square with the world I place a double-bubble level in the camera’s hot-shoe, alternately you could activate the virtual horizon feature while in the Live View mode. It is also advisable to use auto-focus while doing so as the last thing you need to worry about while leaning over the edge of your canoe is focusing the lens manually.

I am eagerly awaiting this season’s Bullfrog photography on Horseshoe Lake as I will be experimenting with the Sony RX100 in an underwater housing for a completely new perspective on froggies.

One of my main reasons for wanting to try the Sigma 15mm f2.8 EX DG Fisheye Lens, which was on loan from Gentec International, the Canadian distributor for Sigma lenses, was for photographing Bullfrogs in the wetland on Horseshoe Lake near Parry Sound, Ontario. When my parents bought our family’s cottage over 30 years ago there were great numbers of Bullfrogs to be found and their signature jug-o-rum chorusing would echo through the night air. Today all but a few individuals can be heard singing at night and locating them can be a chore some days. Fortunately, there is one very reliable fella that always hangs out in the vicinity of a very tiny island, covered with sedges and shrubs, within the wetland. I have had the pleasure of photographing this individual for over and over. For exactly how long I am unsure, but I would guess at least three years. I can often place my hand underneath him and he will crawl aboard and allow me to pose him. Do note that amphibians should NEVER be handled if you have insect repellent or sunscreen on your hands – it is deadly to them.

Each of these frog-scapes were photographed handheld, selecting the Live View function on my Nikon D800, auto-focus and a double bubble level in the hot shoe to make sure the froggies were sitting square with the world in the photos. This is the easiest way I know of to capture such images from the dry comfort of a canoe. Often my hands are submerged in order to hold the camera just millimeters above the water’s surface. I found over-cast conditions to be more favorable as with the extreme wide angle view of this lens it was easy to accidentally see my shadow or that of the camera and lens within the frame under sunny conditions. Also if the camera and lens is held above and over the frogs it is easy to get the camera and lens reflecting in the water in front of the subject, but by hand-holding the rig just above the water this problem is eliminated. A slight downward pointed fisheye lens will create the rounded prespective that works beautifully to show the frog’s within their world. And since the world is round, this is a pleasing perspective :)

Below are some of my favorite frog-scapes photographed while using the Sigma 15mm f2.8 EX DG Fisheye lens.

Johnstone's Whistling Frog_5985

Johnstone’s Whistling Frog (Eleutherodactylus johnstonei) with vocal sac inflated

Every night as the sun began to set during my stay at Search Me Heart in Port Antonio Jamaica, the nights would begin to fill with the choruses of the Johnstone’s Whistling Frog, also known as the Lesser Antillean Whistling Frog. This tiny little frog, which measures roughly 3/4 of an inch in length, is one of the most widely distributed frogs in the Caribbean, mostly due to trade among the islands. It would be very easy for these frog to hitch a ride among bananas and such being traded between neighboring Caribbean islands. These little frogs do not require water to reproduce as the female will deposit her eggs among leaf litter from which tiny froglets will emerge.

Prior to departing for Port Antonio, Jamaica I did a ton of research to learn of various landscape locations I would want to visit and what wildlife species may be indigenous to the region. During my research I discovered that there is roughly 27 species of frogs in Jamaica. Knowing that in advance I decided I should take along my gear that I frequently use for frog photography, however I did not really want to carry the additional weight of my Nikon 105mm micro lens, so I decided to leave that lens at home and follow my own advice here about the Nikon 80-400mm macro lens solution. By using my Nikon 80-400mm VR lens with the Canon 500D Close-up filter and my Nikon SB400 Speedlight, on a flash bracket, I was well equipped to capture these tiny frogs. I did not know that these tiny frogs would be so plentiful among the vegetation of Search Me Heart’s gardens. Each night before heading off to bed I would spend about an hour or so wandering about the lush gardens with a small flashlight, trying to located the frogs as they sang. In the photo above I had to wait patiently for this little fella to commence singing again after I discovered him among some yellowed foliage of wild banana plants and the frog below would show up virtually every night on the very same leaf to chorus. By frequently searching out these subjects I was able to capture some of my most favorite frog images to date.

Golden Poison Frog (Phyllobates terribilis)

I have long wanted to photograph tropical species of frogs and had a wonderful opportunity to do so a couple of months ago. All of the frogs in this post are captive bred and raised in Canada. Since many of these photos will appear in the eBook I am writing on frog photography, it was of the utmost importance to me that none of the frogs photographed were wild caught specimens. One of the chapters in the eBook will provide tips and instructions on photographing captive specimens such as the ones you see here.

One of my favorites is the lovely poison dart frog that opens this blog post – the Golden Poison Frog (Phyllobates terribilis). This is perhaps the deadliest of poison frogs. Its skin is coated with an alkaloid poison (batrachotoxin). It is estimated that one milligram of this poison is enough to kill 10,000 mice, 10-20 humans, or two bull elephants. Yikes! Good thing they are captive bred. Poison dart frogs tend to lose their toxicity in captivity as they are no longer feeding on the ants and termites of their rainforest homes, which is where they get their toxicity from. Nonetheless, poison has never looked so beautiful.

Here are a few additional poison dart frogs from the shoot….more to follow in a later blog post.

Chorus Frog, male, in position to start calling

I have spent the last two nights out in the ponds photographing the Chorus Frogs, Wood Frogs and Spring Peepers. The Spring Peepers emerged about two days ago and began singing. So far, this year is turning out to be one of the best, if not the loudest chorus I have ever heard in my 15 years of living here. While sitting in the ponds, surrounded by a large number of Chorus Frogs, I can honestly say that the sound is utterly deafening this year. I love it! And the best part is these little fellas are quite literally singing all day and all night long. Each night after I have finished photographing the frogs it is so nice to crawl into bed, leaving the bedroom window open, and be serenaded to sleep by these wonderful sounds of spring. Here are a few recent captures from the last two nights. Note, I have never been able to photograph Chorus Frogs in the day as they are too weary and go silent when I get within 50 feet or so of the ponds. At night it is a different story, especially if it is an overcast night. For some reason overcast nights are always more productive. With temperatures predicted to break records, for this time of the year, over the next few days I would not be at all surprised to see the American Toads emerging very soon as well.

Tiny Marsh Provincial Wildlife Area at sunrise

Several days ago I drove over to Tiny Marsh for sunrise. I was greeted with a cloudless sky, not the most pleasing of situations for sunrise imagery. However, I ventured out across the wetland trails to see what might develop. As the sun rose above the horizon I captured a few images, minimizing the cloudless sky and allowing the wetland vegetation to dominate much of the image. Shortly after this I decided to walk out along the boardwalk trail to search for my favorite wildlife subjects – frogs. The boardwalk goes through a forested swampy section of  Tiny Marsh. My timing for this was perfect as there were many young Leopard Frogs at rest on fallen branches and resting among the duckweed in the water. I spent the next three or four hours shooting frogs. Since the frogs were in rather unpleasant lighting situations with the blazing sun casting harsh shadows as it streamed through the surrounding forest I decided to use my Nikon SB-400 on a home-made flash bracket to illuminate the scene. When I shoot frogs I always try to get down to their level if possible, so in this situation I lay down on the boardwalk to get as low as possible. The use of the flash solved the harsh, contrasting lighting, but it created another problem that I dislike very much – flash generated specular highlights. So began the task of eliminating these from the images. Often I will work on a photo very large (500-800%) to evict the highlights. I often use a variety of quick masks and clone stamp to complete this task. Due to the glossy, wet look of the amphibian`s skin this can sometimes be a time consuming task, taking 1-2 hours per image on occasion. I do find the extra effort is well worth the end result and when I complete the task why not try running through the photoshop plugin Fractalius.

Below you will see one of my Leopard Frog images from this day showing the original capture, the optimized file and of course the Fractalius rendering.

On another note, I have started a Facebook fan page today, still lots of work to do on it, but you may check it out here .

For some reason Green Frogs always remind me of the 400 year old folk song Froggie Went-a-Courtin’. I first heard of this song several years ago when Bob Dylan recorded his version of the song. Last week I photographed numerous Green Frogs out in the pond. One frog in particular was quite striking – a uniform green color not the usual mottled appearance that they have. As I was framing a close-up of this fella, pictured above, he lunged forward to bite the lens. When frogs detect movement they usually try to eat what is moving, due to voracious appetites. No worries, I remained unscathed by the attack :).

This season I was finally able to capture Green Frogs with their vocal sacs inflated. This is rather difficult as they only inflate them for a moment, unlike Toads and Gray Treefrogs that inflate their sacs for a longer duration. Here is a selection of Green Frogs from this season.

When you assume a very low camera position, a frog’s eye view if you will, leave some space in front of the frog and you will be able to capture the frogs reflection also. As you can see in the two images below.
