Spring Peeper_7343Spring Peeper with Vocal Sac Inflated

With the frog ponds behind my home destroyed, I traveled north to the Parry Sound region to first open the cottage up for another season and to visit one of my favorite temporary ponds that is usually highly productive for American Toads, Spring Peepers, and Gray Treefrogs. The first night was very cool and only the Spring Peepers were out chorusing. Finding Spring Peepers requires a boat load of patience due to there tiny size, but they usually co-operative once you do locate them. The above little fella was found in perfect position on a small silver birch sapling and his placement on the branch would allow for a beautiful poster-like background.

The main problem encountered with photographing frogs at night with flash is spectral highlights. These are blown-out highlights caused when the light from the flash hits the frog’s glossy skin and surrounding wet vegetation. Often I will spend a lengthy amount of time cleaning up these undesirable and unnatural highlights. On occasion, as you can see in the before and after versions below, there will be extensive blown-out highlights. For this particular image there was little good skin left, on the frog’s nose, to work with to evict the highlights so I looked back through the series of images I photographed of this frog on the branch. Sure enough I was able to find another photo where the flash hit the frog’s skin at a slightly different angle resulting in fewer blown-out highlights. I now had my solution. I opened both images into Photoshop and rather than use the ‘Tile’ viewing, I opened them into ‘windows.’ I then made a quick mask of the nose in the image with fewer highlights and moved it into position on the optimized image. The remainder of the flash generated highlights were evicted using the clone stamp tool whereby I would vary the hardness depending on where in the image I was cloning.

This Spring Peeper image was created using a Nikon D800 with a Nikon 105mm Micro lens attached. The flash was a Nikon SB400 Speedlight on a Wimberley F-2 Macro Bracket (the best flash bracket I have ever used for frog photography). A small mini-mag flashlight is affixed to the SB400 with two elastics. The small flashlight makes focusing on these critters at night a breeze.

Do remember to click on the images to see the larger, sharper versions of each. The image below shows the original RAW capture straight out of the camera with no adjustments made to it, and the optimized image.

A quick reminder to folks about Denise Ippolito’s presentation for GRIPS Camera Club in Kitchener, Ontario on Monday June 3rd at 7:30 pm. Denise is a very talented and highly creative photographer with imagery bound to fill you with inspiration. If you are in the vicinity do make plans to attend.Hope to see you there 🙂
