La Palma Glass Frog – unedited RAW Image File

The above photo is an unedited RAW image file of a La Palma Glass Frog that was photographed at our popular “Dart Frogs of the Amazon Rainforest Photographic Workshops” with a Nikon D500, Nikon 105mm Micro Lens, and a Nikon SB400 Speedlight mounted on a Wimberely F-2 Macro Bracket. While the flash-generated spectral highlights are well controlled and their is minimal debris to clean-up on the Monsterra leaf, used as a prop, there is one thing that bothers me about this photo as presented. What is that? I do wish that I had switched to the vertical orientation to best represent the frog’s pose on the leaf, however, all is not lost and my wish can be easily achieved with a few simply steps in Photoshop.

After making some initial edits to the image in Adobe Camera Raw the image is brought into the Photoshop interface as seen below.

La Palma Glass Frog Photoshop Interface with the Crop Tool selected and the Content-Aware box checked

Once the image is opened in Photoshop I select the Crop Tool and the Ratio option from the drop down box in the upper left corner of the interface. When using the Ratio option you can select the exact pixel dimensions that you want to use. In this case I entered the pixel dimensions fro a vertically oriented image photographed with a Nikon D500. With crop dimensions now in place over the image I simply drag out the corners of the crop for the desired look and position the frog where I want it to be within the frame. Before I click the check mark to perform the desired crop I check the Content-Aware box. By doing so Content-Aware will fill in the black areas outside of the actual image area to match the surrounding elements. In this case it will fill in the sliver along the bottom and the larger portion at the top. The natural indent of the Monsterra leaf will be fixed later with a simple quick mask removal technique.

After performing the above mentioned steps, the optimized image file for the vertically oriented La Palm Glass Frog image can be seen below. In this situation the Content-Aware did an amazing job of replicating the leaf to fill in the areas that were outside of the image. The Clone Stamp tool was used at varying hardnesses to evict the flash generated spectral highlights and debris on the leaf surface. The lower left corner of the image where the indent of the Monsterra leaf was creating a distraction was fixed quickly and effortlessly by utilizing a Quick Mask. To learn more about using Quick Masks and other techniques to easily optimize image files take a look at APTATS 1 & 2.

I recently was reading about an interesting technique for creating water blurs on Moose Peterson’s blog. This technique works wonderfully for river scenes, waterfalls, and along lake shores or oceans. In the image above of beautiful Red Rock Point on Georgian Bay the waves were crashing quite nicely and I was able to create a nice scene with the waves rolling in. I did want to create an image with a much longer exposure, however, the time of day would not permit such an exposure and my 10-stop Neutral Density filter was back in the car. Since I was suffering from nagging lower back pain I was not about to make the trek back to the car to get the filter. Then I remembered the article that I read about utilizing the camera’s multiple Exposure feature to create the blurred look to water imagery. I set my Nikon D800 to the Multiple Exposure feature and dialed in a six frame exposure. Below you can see the effect of this technique. Do note that due to very blustery conditions there is some blurring to the trees as a result of the wind.

Male American Toad (Bufo americanus) chorusing in pond at night.

Male American Toad (Bufo americanus) chorusing in pond at night.

I have been quite busy these last few weeks, with little time to get out for fresh images. This week with our night time temperatures being relatively warm I had to head out in search of some photos of chorusing toads, which I could hear far off in the distance. Since the ponds behind my home were destroyed a couple of seasons ago I now must travel further a field for images. I have located another productive pond about 15 minutes from my home, so I drove there a couple of nights ago. The toads were being most cooperative as song filled the air.

When I photograph frogs and toads at night I will use a head-lamp as well as two tiny flashlights attached to the flash head with elastics, these are used for focusing at night. Another useful way to use external lighting to assist with night-time focusing is to use a small clip-on flashlight and fastening it to sturdy elements within the pond such as that of a dried cattail stem. By doing so you can aim the light quite accurately to assist with the focusing. This is exactly what I did to photograph the toads in this blog post.

Often I have noticed that the toad’s colorations can vary greatly among each specimen that has arrived at the pond. I was delighted to find this specimen with it’s lovely golden yelow tones.

A Waterfall Along the Nottawasaga River, Organgeville, Ontario

Secluded Woodland Waterfall on the Nottawasaga River near Orangeville, Ontario

The above artistic rendering of a small waterfall located along the Nottawasaga River near Orangeville, Ontario was created using the Photoshop plug-in Topaz Simplify, which is available from Topaz Labs. I visited this waterfall a few years ago and have had the image sitting on the back-burner ever since. This evening I decided it was time to optimize the image file and play around with creating a painterly-like version of it as well. Below you will see the original version of this lovely, secluded waterfall.

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.

Johnstone's Whistling Frog with HighLight Warnings

Johnstone’s Whistling Frog with HighLight Warnings

Above you see a photo of a Johnstone’s Whistling Frog that I created in Port Antonio, Jamaica. This was the first image that I created of these lovely little frogs during my stay in Jamaica. Being excited at photographing a new species I forgot to check my camera settings before clicking the shutter. When I scrolled back through a couple of the frames to confirm my exposures were correct I realized my error and immediately dialed in the correct settings but the frog jumped away. I was left with this image, which on the camera’s LCD screen was showing what appeared to be blown-out highlights (note that in the above image I made adjustments in ACR to mimic what I was seeing on the camera’s LCD screen – the highlight warnings on the camera would have been black instead of red as shown above).

Directly below is the same image as it opened in ACR. You can see that the highlights are not too bad after all. The red highlight warnings seen here red here are the flash generated spectral highlights, which are indeed blown-out with no detail whatsoever.

Now look at the optimized image file below. After making the required slider adjustments in ACR I was able to recover a great deal of detail in what the camera originally indicated was blown-out and lacking detail. I then opened the image in Photoshop and using a series of Quick Masks and Clone Stamp Tool applications addressing the flash generated highlights.

This is why I do not delete photos, in the field, as seen on the camera’s LCD screen. I always wait until I am editing a trip’s images when back home at the computer.
