In frog photography patience is a virtue and good things will come to those who wait. On May 30th of this year (yes, I am way behind on processing my image files) the night time temperatures were perfect for the male Green Frogs to congregate at a nearby wetland and chorus to entice females to the pond for mating. As I waded about the pond I noticed one particular male that was clinging to an old cattail stem, while floating in a section of the pond with no distracting debris floating in the water. I slowly made my way over to where he was and once directly in front of him, I slowly moved myself into a kneeling position in front of him. As I did this I was reminded of the hole in my chest waders as cold pond water began to trickle into the waders. Also it was a perfect night for the first mosquitoes of the season to emerge and feast upon your truly. I do not use any sort of bug spray when I am out photographing frogs and toads due to its toxicity to them. I would hate to handle a frog or toad with bug spray on my hands as it would be harmful and likely fatal to them. The time span between the above image and the one below is exactly seven minutes. Once I was in position, I waited and waited and waited, all the while swatting mosquitoes with slow-motion-like movement so that I would not disturb the frog. As I was waiting I kept watching the frog’s torso, as it began to fill with air I knew it was going to call very soon. In the above photo you can clearly see how bloated the frog looks and then in one quick moment all the air is pushed out, inflating the vocal sac, and the Green Frog’s signature loose banjo string-like call can be heard.

In 2012 Sigma released the Sigma 180mm f2.8 APO Macro EX DG HSM OS Lens. In July of this year I had the opportunity to spend about a week with the lens, to give a thorough workout, as it was on loan to me from Gentec International, the Canadian distributor for Sigma lenses. The Sigma 180mm Macro lens is physically a large lens yet does handle very nicely. It is equipped with Sigma’s Optical Stabilization feature, which will compensate for about 4 stops. At the time of this lens’ release it was the only 180mm Macro lens to offer such superb stabilization. It is also a fast lens with a maximum aperture of f2.8 therefore the viewfinder is bright making manual focus easy (should you prefer to manually focus your macro lenses – I generally do). Since my main objective was to use this lens handheld from the canoe for frog photography and wetland details too, I was very eager to put the Optical Stabilizer to the test. Some other features that are noteworthy to mention for this high-performance lens are:
- Three low dispersion glass elements for excellent correction of both axial chromatic aberration and lateral chromatic aberration.
- Hyper Sonic Motor delivers auto-focusing that is quiet, fast, and accurate.
- Multi-layer coatings to minimize flare and ghosting.
- Accepts 86mm size filters.
- Tripod collar to easily switch from horizontal to vertical orientations.
- Minimum focusing distance of 18.5 inches.
- Magnification ratio of 1:1 at the minimum focusing distance.
Let’s head out into the Horseshoe Lake wetland in the canoe and see what we can find. Do note additional info that is provided in the image captions.
One of the first things that did take some getting used to on my part was working with the greater minimum focusing distance. Since I am most accustomed to using my Nikon 105mm Micro Lens which has a minimum focusing distance of 12 inches I often found that I was getting in too close with the Sigma 180mm Macro lens and would have to adjust my positioning to accommodate for the greater minimum focusing distance. This is by no means a hindrance though, in fact the greater minimum focusing distance has many benefits to it. If you enjoy photographing butterflies, small lizards, snakes or other often difficult to approach subjects, the Sigma lens will permit photographing from a greater distance which in-turn will lessen the chance of entering the animals comfort zone causing them to take flight.
Hand-holding the Sigma 180mm f2.8 APO Macro EX DG HSM OS Lens in the Horseshoe Lake wetland was a very enjoyable experience and allowed me to create numerous images that would have been difficult to do otherwise, as it would have been impossible to set-up a tripod in the soft mucky bottom. Do note that macro lenses as a rule are some of the best optics available and I will often use them for landscape imagery as well, including some of the intimate wetland scenes below.
After photographing several different scenarios in the wetland environment I decided to head into the woods with my tripod and photograph some woodland details. Many years ago I used spend much of my time in woodlands photographing woodland plants, tree bark details and any bugs that I could find. It was a ton of fun to take the Sigma 180mm Macro lens into the woods to re-visit my photographic roots.
And last but not least, I could not resist the temptation to create a pleasing blur of a lovely cluster of ferns growing alongside of the cottage road. To create the blurred effect I simply stood at the edge of the road, looking down upon the ferns and using an in-camera sideways motion with a shutter speed of 1/15 created an image that revealed the subject matter, yet had a pleasing amount of blur to it as well. This is a technique that I learned from colleague, mentor and friend Denise Ippolito.
Conclusion: The Sigma 180mm f2.8 APO Macro EX DG HSM OS Lens was an absolute joy to use. The 18.5 inch minimum working distance took some getting used to on my part, but is very beneficial to photographing subjects that are prone to spook very easily. The Optical Stabilization feature’s performance is superb offering a stable solution to creating hand-held imagery in often difficult situations. While I mainly used the lens hand-held, the tripod collar did make switching from horizontal to vertical orientations effortless when a tripod was in use. Alternately, the tripod collar would offer an excellent and very simple solution to mounting an off-camera flash for night-time macro photography, much like I do for my night-time frog imagery whereby I use flash 100% of the time. I would highly recommend this lens to anyone looking for a macro lens, or looking to upgrade to a longer focal length macro lens. It is a large, sturdy, and well built lens that delivers superb image results. I only wish that I had more time to fully explore the capabilities this lens has to offer.

Without a doubt my most often go-to lens for Bullfrog in the wetland on Horseshoe Lake is my Sigma 15mm f2.8 EX DG Fisheye Lens, and more often than not I select the Nikon D800’s 1.5 sensor crop when creating these images. By selecting the 1.5 sensor crop I am effectively using a 22mm fisheye lens with a close focusing distance of 5.5 inches. The close focusing capabilities of the Sigma 15mm Fisheye lens are hard to beat when it comes to creating these Bullfrog portraits.

A few months ago there was a wonderful exhibit of tropical frogs at Ontario’s Royal Botanical Gardens in Burlington. One day in April I made a trip out to see and photograph some of the species that were on display. Photographing such animals through the glass walls of their enclosures can often be a bit troublesome due to finger prints and scratches on the glass, however, there are few simple techniques that can be employed for success. When I photograph captive subjects through the glass walls of their enclosures I will always get as close to the glass as possible to eliminate / reduce the risk of scratches and fingerprints from showing up in the resulting images. To get as close to the glass as possible I ensure that I am using my rubber lens hood so that I do not become one of those individuals that has left unsightly scratches on the enclosures. A relatively large rubber lens hood aligned flush with the glass wall of the enclosure will often reduce the risk of the flash from reflecting off the glass, ruining the photos when it fires.
At public exhibits I often find it too difficult to work with a tripod, mostly due to the number of visitors and elementary school class trips that attend. As a result I do much prefer to work with flash and when I photogenic subject and pose is noticed I can then quickly grab a few photos without affecting the other visitors that are also there.
For the image above of the Dendrobates auratus I was able to get a very low perspective and a pleasing background by placing the lens flush with the glass wall at the moment the dart frog jumped to the front of the enclosure. Dart frogs are often very quick and sometime difficult to photograph, but this image gives the impression that I am lying flat on the ground in their rainforest home, yet I was dry and comfy :)
Pictured above is an African Bullfrog. What is not to love about a frog with teeth! These frogs will eat anything they can stuff in their mouths from insects to full grown mice. You will notice that in this image the camera was pointed downwards, with the lens close to the glass and in a downward postion the flash will not reflect back into the resulting images, however, if I tried the same perspective after taking a few steps backwards the flash would be noticeable and the images would be deleted.
Warty skinned frogs such as the above Argentine Horned Frog do pose some challenges with flash generated spectral highlights. In Photoshop I will often evict the most noticeably distracting highlights, for many of the smaller ones as seen above I will open Selective Color and add a touch of Black to the White channel which tones them down a bit.
Treefrog specimens are usually very uncooperative subjects as they are mostly nocturnal so when one is encountered alert and wide-eyed grab as many photos as you can because they will probably go back to sleep very soon.
Below is a Fire-belly Toad which is an Asiatic species and very common in the pet trade. Believe it or not I actually used to keep Fire-belly Toads in a large terrarium many years ago and they lived for roughly 21 years.
After photographing many of these wonderful frog species from around the globe in a single afternoon I thought it would be fun to take one of the images and create a frog fract using the Photoshop plug-in Fractalius. Below is a Goliath Frog skeleton. The Goliath Frog is the largest frog in the world, they live alongside streams and such in Cameron, in Africa.

For the first time since the inception of this blog I went an entire month without a new blog post. Yikes! Sorry folks. The month of June quickly became a hectic month me as I was spending many evenings driving to various frog ponds near my home and the cottage in search of fresh froggie imagery, processing a large, multi-print, fine art order for the corporate head-quarters of a financial institution in the United States, and several other responsibilities that were leaving me little time to post any new content. The good news is that I was by no means slacking off on creating fresh imagery and now have many new photos, tips, and info to share in upcoming posts.
Each of the frog images within the post were created throughout the month of June during the peak of the spring chorus (breeding season) and surprisingly enough I do still hear the American Toads and Gray Treefrogs chorusing around my home, mostly due to the cool nights prolonging the breeding season this year.
During my travels to various ponds in June I discovered two new ponds that have become my preferref locations for frog photography. At one pond I was amazed at the sheer numbers of American Toads that were floating out in the deeper, inaccessible sections of the pond. They would make their way in towards the stands of last season’s dried cattail stems to chorus. Also among the dried cattail leaves were vast numbers of Spring Peepers. Finding a Spring Peeper among a stand of dried cattail leaves is like looking for a needle in a haystack. Most often the Spring Peepers will be chorusing well above the surface of the pond and once discovered, a slow approach is mandatory as they will become aware of your presence quickly and stop chorusing. If this happens remain still for about 10-15 minutes and you will soon be rewarded for your patience.
At the second pond that was newly discovered there were large congregations of Northern Leopard Frogs, which were quite co-operative as well as Green Frogs. Creating images of these two species with their vocal sacs inflated has always been a challenge for me as the call is quick and seemingly unannounced, but upon carefully studying the frog’s behavior I have noticed that they do indeed give very subtle clues that they are about to croak :) Green Frogs will quickly flap the skin on their throat a couple of times just prior to calling, and the Northern Leopard Frogs (as do other frogs) will noticeably begin to draw air in making their body appear inflated. Once they look pretty full of air, a song is soon to follow.
This season I wanted to try creating some night-time imagery of frogs that had a slightly different look to them and thus I decided to head-out into the ponds with my Sigma 15mm Fisheye lens to see what I might be able to create. Below are two of my favorite fisheye night frog photos. When using the fisheye lens for these images it was imperative that I paid close attention to the placement of the flash, cords, and mini-flashlight (used for focusing) as they would end up within the image if placed incorrectly.
Of all the frogs and toads I get to photograph, none are more enjoyable than the Gray Treefrog. Often Gray Treefrogs will strike interesting poses as they climb around vegetation. Below are a few more Gray Treefrog photos that were created over the past month.

One thing I was looking most forward to upon returning to the Caribbean Island of Cayman Brac in March was photographing Cuban Treefrogs. Although the Cuban Treefrog is an invasive species throughout the Caribbean known to feast upon smaller frog species, they are still a beautiful treefrog. When I visited Cayman Brac in February 2014 the Cuban Treefrogs were very easy to locate however, in March 2015 this was not the case. It had been relatively dry prior to my return trip and I think some of the frogs moved on to wetter areas or were lying dormant somewhere. After three very unsuccessful nights of searching for these frogs I remembered one very important fact about treefrogs – they will most often hang-out around human structures and porch lights as the lights tend to provide these amphibians with an all-u-can-eat buffet :) I began searching the decorative concrete wall surrounding the villa and alas I found a Cuban Treefrog sleeping away the day. The next plan was to monitor this frog as night began to fall so that I could finally create some fresh Cuban Treefrog imagery.
Once I had discovered this frog’s day-time resting place I was easily able to locate and photograph it over the course of several nights. Here is a selection of my most favorite froggie images from the lovely island of Cayman Brac.
As you scroll through the images below do note that I have used a Canon 500D Close-up Filter on my Nikon 80-400mm VR lens. This close-up filter is a simple and relatively inexpensive option for turning lenses such as the Nikon 80-400mm and the Canon 100-400mm into close focusing macro lenses. Here is a photo to illustrate the Canon 500D Close-up Filter attached to my Nikon 80-400mm VR lens.
Also note that each of these images were photographed handheld using the discontinued Nikon Speedlight SB600 on a Wimberley F-2 Macro Bracket (the best flash bracket on the market for macro work today).

I returned from my 14 day stay on the Caribbean island of Cayman Brac late on March 19th. Since my return I have been busy getting caught up on various things and processing a few of my initial favorites, from the vast number of images created during the trip. Today’s post will highlight my most favorite photos from the trip and in subsequent posts I will get into the nitty-gritty of what worked, what didn’t work, and the techniques used to create the images.
During my trip there were many lovely sunrises, a few nice sunsets, lots of Brown Booby chicks, reptiles, amphibians, and it seemed like with each day of snorkeling, which was everyday, I found something really cool to photograph in the ocean too :)
Here are a few images from this recent trip to Cayman Brac.
