The La Palma Glass Frog (Hyalinobatrachium valerioi) is a small tree frog (about one inch) endemic to the rainforests of Costa Rica. When view from underneath you can see all of their internal organs, blood vessels, and bones – hence the name glass frog. During each Dart Frogs of the Amazon Rainforest Photographic Workshop we bring this species out as a bonus species. The above image is optimized from a horizontal capture as can be seen in the unedited RAW directly file below. In hindsight this fantastic pose on a Monsterra leaf should have been capture in both horizontal and vertical orientations. Hindsight and Photoshop knowledge is a wonderful thing because with a little tweaking you can have both.

In the screen shot of the Photoshop interface below you can see that I have selected the Crop Tool (I set the Ratio to 3712 X 5568 pixels, the same dimensions as an image from a Nikon D500). I then moved the crop tool and enlarged the ratio until I had the frog positioned exactly where I wanted it to be. As you can see from the screen shot below, the crop tool as been extended well beyond the actual image. This was done deliberatley. Note that I have checked the Content Aware box (please click on the image to view the larger version making it easier to see). All I have to do now is click on the crop tool’s check mark to initiate the cropping and let content aware will fill in the areas beyond the frame. usually there may be a little touch up needed as the content aware may not fill in the spaces perfectly, but in this case it did a wonderful job with no additional touch up required. The final task that was performed was cloning out the flash generated spectral highlights on the frog. I often find that enlarging the image to about 400% simplifies the task of cloning out these highlights, although it can be a time consuming task.

And last but not least is the optimized horizontal orientation of the La Palma Glass Frog. Please do remember to click on the images to view the larger, versions.

A quick update on the recently announced Dart Frogs of the Amazon Rainforest Photographic Workshop on Saturday, November 25th as it is now SOLD OUT (wait list). If enough interest is generated or the wait list becomes sufficient we will add a second date on Sunday, November 26th. If you missed out on getting your name in for the Saturday date, it is not too late, please send me an email by clicking here asking me to add you to the wait list.

Today’s post again features imagery by two participants in the recently concluded dart frog workshop. I love the pose of the Ranitomeya fantastica on the branch in the opening photo that Paul Infelise captured. The male Denrobates tinctorius “Mount Matecko” below seems to have a tough guy look to him and although a tad tight in the frame I really do like the pose on the Dendrobates tinctorius in the final image by Paul.

Mark Pomeroy sent along a small selection of his imagery from the day as well. Each of the frogs that mark sent are very small, measuring roughly the size of a thumb nail, with the exception of the Ranitomeya reticulata which is a little bit smaller than that! Mark’s Ranitomeya variablis on the Monsterra leaf is posing for us quite nicely and the placement within the frame works well too. The La Palma Glass Frog (Hyalinobatrachium valerioi) has a very inquisitive look to its pose. The dark background creates the effect that this is a night time capture, which is an accurate representation for this nocturnal species. The Glass Frogs are always brought at the end of each event as a bonus species and they never disappoint. As mentioned previously the Ranitomeya reticulata is slightly smaller than a thumb nail in size and I like that mark kept it small in the frame as I think it enhances the diminutive size of this incredibly tiny, yet colorful dart frog.

This post is feature several images from some of the participants that attended the recently concluded Dart Frogs of the Amazon Rainforest Photographic Workshops on August 19th & 20th. We had a great group of folks for each date and tons of fun creating great images. We incorporated the use of props for some species to illustrate just how tiny they are. These props included a ten cent coin and the thumb of yours truly for a human touch 🙂 I am really proud of the images that the workshop participants created during these two events as well as their post processing skills. I will share more images from other participants when they are able to send their images along. Below are a few images from the first group of participants that were able to submit their images this week. Stay tuned for more images soon 🙂

First time participant Alan Jones made the trek from Michigan to attend both days of the workshop and created many great images using his Nikon D800 with the now discontinued Nikon 200mm Micro lens and the R1 Wireless Close-up Speedlight System I love the upright pose Alan captured of the Epipedobates tricolor, the side profile of the Phyllobates terribilis, and the low perspective for the Dendrobates leucomelas.

Jennifer St. Louis was also a first time participant at the dart frog workshop. Jen was using a small soft box on her camera mounted flash to add a soft even light, which is something I may start incorporating. I absolutely love the image she captured of the Ranitomeya flavovitta below. Her low perspective allows the frog to stand out beautifully against the poster-like, out-of-focus background. Her image of the Hyalinobatrachium valerioi on the Monsterra leaf creates a nice sense of scale for this tiny tree frog and her Dendrobates leucomelas image really pops against the soft greens of the same leaf.

Return workshop participant Don Johnston captured the Epipedobates tricolor on a 10 cent Canadian coin which really gives us a great sense of scale for this tiny but colorful frog. Don was also using the discontinued Nikon 200mm Micro lens with a light source provided by his Nikon SB900 Speedlight mounted to a Wimberley F-2 Macro Bracket. The benefit of using such a lens is that you gain more working distance, which can be most beneficial at times. Don’s capture of the Dendrobates tinctorius on the soft green moss (direct from Peru) pops nicely as does his Phylobates terribilis sitting on the Cordelyne leaf – what better combination than a bright yellow frog sitting on a bright purplish-pink leaf 🙂

Sherry Butts’, a returning workshop participant, opening image of the Ameerega hahneli reaching up to my thumb nail was only made better when the frog actually climbed up onto my thumb nail. Sherry was using one of my home-made flash diffusers to add soft, even lighting and while these custom-made diffusers are impracticable for field use they allow the workshop participant to create stunning imagery without the need to invest in expensive off camera flash brackets. Sherry loves going for a creative look in her images and as a result applied a beautiful texture overlay to her capture on the Phyllobates terribilis on a leaf stem.

Phyllobates terribilis

This past weekend we held our Dart Frogs of the Amazon Rainforest Photographic Workshop at the Crinan Community Centre located just west of London, Ontario. We had a great group of participants in attendance and a couple of folks that took advantage of the two day discount that was offered. Several participants were repeat participants from the first event held in May of this year. One lucky participant from each of this weekend’s events walked away with a fabulous door prize – The Plamp that was graciously supplied by Wimberely.

Here are a few of my initial edits from a few of the images I captured in between assisting participants with their images. As usual during each event we bring out a couple of bonus species at the conclusion of the day. For this event we featured the La Palma Glass Frog (Hyalinobatrachium valerioi) and The Fringed Leaf Frog (Cruziohyla craspedopus).

In the coming days I will be featuring some participant photos.

In September I am travelling to Tarapoto, Peru on a scouting trip to be able to add an incredible rainforest photographic workshop opportunity to my 2018 line up of available workshops. Stay tuned for news about this upcoming workshop.

The next Ontario based Dart Frogs of the Amazon Rainforest Photographic Workshop will be held in Mississauga, Ontario in November. Once the logistics for this event are finalized I will announce the event here.

Two spaces have just opened up for the Saturday, August 19th Dart Frogs of the Amazon Rainforest Photographic Workshop. One lucky participant will walk away with an awesome door prize graciously supplied by Wimberley. To find out more information about the workshop please click here and contact me here to arrange payment via email transfer or by cheque and reserve your spot. It would take tens of thousands of dollars to explore the rainforest to photograph a fraction of the species that you will be able to photograph on this date in the comfort of the Crinan Community Centre located near London, Ontario. Hope to see you there!

Due to the very successful, first-ever Dart Frogs of the Amazon Rainforest Photographic Workshop in May I will be hosting two photographic workshops, with new species of dart frogs in each session, in August at the Crinan Community Centre located at 13568 Dunborough Line in West Elgin, Ontario, located near London, Ontario.

The dates and times for these workshops are:

Saturday, August 19, 2017  10:00a.m. – 3:00 p.m.  (SOLD OUT – wait list)

Sunday, August 20, 2017       10:00 a.m. – 3:00 p.m. (SOLD OUT – wait list)

The space for each workshop is limited to a maximum of 8 participants to allow ample time for folks to photograph each species. Each workshop will feature different species and colour varieties of dart frogs.

These are the only workshops available whereby you will be able to capture stunning imagery of 15 different species of dart frogs endemic to the Amazon rainforest. It would cost tens of thousands of dollars to explore the Amazon jungle on your own in hopes of photographing a mere fraction of these species. These workshops, in partnership with Understory Enterprises, will bring you an incredible opportunity to photograph these 15 species of dart frogs for only $195, plus HST, in a comfortable atmosphere with natural studio set-ups. The recommended gear for photographing these tiny frogs is a macro lens and off camera flash. Alternately, using high quality close-up filters such as the Canon 500D filters will allow many lenses such as the Nikon 80-400mm or Canon 100-400mm to focus close enough for these small subjects. Please contact me here if you have any equipment inquiries when registering for this workshop. I also provide custom made flash diffusers that will allow folks to capture equally stunning imagery using camera mounted flash as well.

Please note: folks wishing to sign up for both dates will receive a 15% discount, which works out to $339.13 plus HST to attend both sessions.

Coffee, tea and snacks will be provided during the workshop.

To register for this workshop folks may contact me by clicking here for availability.

Payments can be made via email transfer or by cheque made payable to Andrew McLachlan.

Hope to see you there!

The Dart Frogs of the Amazon Rainforest Photographic Workshop is fast approaching with limited space remaining. On Saturday May 13th at 10:00 am at the Crinan Community Centre located at 13568 Dunborough Line in West Elgin, Ontario those that are already registered will be creating incredible imagery of a vast variety of dart frogs endemic to the forests of Peru. In order to photograph this vast variety of frogs in the wild it would cost tens of thousands of dollars and extensive, guided travel, but in this four hour photographic workshop you will create impressive imagery of nature’s most colourful animals, in natural settings, in comfort.

One lucky participant will be walking away with a door prize donated by Wimberley!

One such frog we will be photographing is Phyllobates terribilis aka “The Terrible One.” This frog is the deadliest vertebrate on the planet with enough alkaloid toxins to kill 100 people. Fortunately all dart frogs in captivity lose their toxins and are perfectly safe. They develop their toxins through the ants and termites that they feed on in the Amazon Rainforest, without this food supply they lose their toxicity.

All frogs used in this workshop are captive bred specimens.

Here are a few examples of what you will be able to capture if you register for the workshop. Do note that there are limited spaces remaining. For more information please click here.

On Sunday April 9th, two days after receiving a late season snowfall, the temperatures rose to just above the 20 degree Celsius mark in south-central Ontario. Perfect conditions for a night time excursion to the neighborhood frog pond. As I drove through the night to reach the pond I did so with the car window rolled down and as I neared the pond’s location I could already hear the deafening chorus of hundreds of Spring Peppers. Typically at this point in the season it is only the Spring Peepers, Chorus Frogs, and Wood Frogs that are chorusing. Other species will generally emerge a few weeks later. On this night I did note many Green Frogs, and American Toads had also emerged but had not yet begun to chorus. I spent about two hours wading through the shallow waters of the pond searching out the crooners and also keeping a close eye on a newcomers to the pond – Beavers. Late last fall it appears that beavers have moved into the pond creating a dam to retain a deeper depth to the pond which should benefit the frog’s offspring in their metamorphosis to adulthood without the risk of the pond drying out. When searching for these frogs it is often best to search the grasses and shrubbery at the pond’s periphery, as this is where they will be discovered most often. On this first excursion I was pleasantly surprised to locate a juvenile Bullfrog as well.

Here are a few images that were created on this first excursion into this year’s spring chorus.

Please remember to click on each photo to view the larger, sharper version.

Have you have ever thought about trying your hand at photographing frogs and toads at night during the spring chorus. If so, send me an email to schedule a private in-the-field session to learn how I photograph them under the cover of darkness.

Workshop participant Chuck Carson recently shared a few of his images that he created during my January Reptile & Amphibian Workshop that was held at Reptilia. I love the peek-a-boo pose on the Red-eyed Tree Frog and the dead-on stare from the Green Tree Python has excellent sharpness from the tip of the nose to the eyes, which is where you want it to be. The Dendrobates auratus was photographed on some dried oak leaves to mimic the debris on the forest floor  that these colorful dart frogs call home. Similarly the Fire Salamander that is endemic to Europe was photograph in a mini-pond set-up with lichen covered tree bark to resemble native habitat for these large salamanders. Chuck also did very well with these latter two species, especially with the very jumpy dart frog and also by paying close attention to the salamander’s reflection in the pond, being sure not to cut it off on the bottom edge.

Red-eyed Tree Frog

Red-eyed Tree Frog – captive

Today’s post will feature imagery from Tim Harding. I first met Tim a couple of years ago at Tiny Marsh near Elmvale, Ontario. Tim signed up for my recently concluded frog and reptile photographic workshop that was held at Reptilia on January 7th and captured some lovely images. We had a great turn out of talented folks and I hope to feature more imagery from the workshop participants as they submit their images. Here are a few images that Tim was able to create during the workshop. As usual, the Red-eyed Tree Frogs performed perfectly and posed very co-operatively atop the pink bromeliad blossom. The Vietnamese Moss Frogs with their superb, camouflage coloring blend in nicely on a large, lichen covered piece of tree bark. The dendrobates auratus dart frog with its incredibly bright colors really pops when placed on a few old dried oak leaves to create a forest floor-like setting. And finally the Fire Salamander gives us a nice pose while it is crawling around on a large section of moss. Tim was using a small softbox on his off camera flash to help soften the light. Using small softboxes is an excellent way to soften the harsh light of a bare flash bulb and often they will help to reduce some, but not all, of the flash generated spectral highlights as well.
