I have long wanted to experiment with over-under, or also known as split shots, of Bullfrogs in their watery worlds. Several days ago I gave it a whirl for the first time and cannot wait to get back up to Horseshoe Lake to create more of these images. Each of these over-under images was created handheld from the canoe using the Nikon D500 and the Laowa 15mm 1:1 Macro Lens in an Ewa Marine Housing. Why did I use a crop sensor camera to create these images with the Laowa 15mm Wide Angle Macro, quite simply because the 15mm focal length will vignette horribly with a full frame camera inside the Ewa Marine bag. The 15mm focal length on a crop sensor camera works perfectly though. The Live View feature was activated to assist with composing and focusing each of the scenes. I was unsure how the Laowa lens would perform inside the Ewa Marine housing, but was more than pleased with the results, considering that the Laowa lens is a fully manual lens. The easiest was I found to capture these photos was to place the camera and lens inside the Ewa Marine housing but to not use the rail clamp to close the housing. This allows the top of the housing to remain open allowing my hand to easily focus the manual lens. The easiest way to ensure sharp focus while using the Laowa lens and Live View is to enlarge the view to 100% on the LCD screen and focus on the frog’s eyeball. To quickly enlarge the view to 100% over the frog’s eyeball I pre-position the Live View focusing sensor over where I want the frog’s eye to be positioned within the composition. I then press the center button on the Nikon D500’s multi selector to immediately attain a 100% view, allowing me to accurately focus on the frog’s eyeball and capture the intended frame.

I am often asked “How do I get so close to these frogs?” The answer – large bullfrogs tend to be more tolerant than the juveniles. A slow approach works best as do slow movements inside the canoe. Any sudden movement triggers a flight response. Once the canoe is in position beside a chosen subject I kneel down in the canoe and slowly move the camera into position. For many of these images the front of the lens is only about 2-3 inches away from the subject.
