One Less Yellowstone Cutthroat

While travel along the Jackson Hole Highway near Oxbow Bend, we encountered a Great Blue Heron fishing in the Snake River.  Due to its unique geographical location as a wide shallow bend in the Snake River, Oxbow Bend is a target-rich environment for photographers.  During the spring, Moose, Deer, Coyote, Coots, Cranes, Grebes, Herons, Pelican, and many smaller birds can all readily be observed here.

The fishing strategy of the Great Blue Heron, Ardea herodias, involves a slow wadding stealth walk.  When a fish is spotted the long sharp beak snaps shut around the fish and holds it securely.  The fish is then swallowed hole.  The quarry here is the much-sought-after Yellowstone Cutthroat Trout (Oncorhynchus clarkii bouvieri).

In the this sequence of images, we observe the entire process, from capture through consumption.  The result…one well-fed Heron, and one less Snake River Cutthroat Trout.

Images in this entry were recorded at ~18:00 MDT on June 2, 2011, using the Nikon D700 and the AF-S NIKKOR 600mm f/4G ED VR lens with the AF-S Teleconverter TC-14E II – that’s 1275mm effective.  Processing included capture sharpening using PhotoKit Sharpener, blending the blue channel into the red channel in luminosity blending mode, followed by contrast enhancement of the red and green channels using curves adjustments again in luminosity mode to preserve the native color balance.  Additional contrast enhancement was applied using Nik Viveza 2 and light edge darkening was applied using Nik Color Efex Pro 3.

Grand Tetons Beyond 830 nm

Photography at Grand Teton National Park presents some challenging timing issues.  Since you will most likely be shooting from a location along the eastern side of the Tetons, your best light will come at dawn, and there are no very good options for late afternoon shooting.  Of course these rules only apply to visible light – head over to the near IR and you open up some excellent additional possibilities.

In my view, and I believe some of the images included in this entry may back me up, the near IR may have some distinct advantages over convention visible light BW rendering .  In addition to the ascetical advantages, there are three significant technical advantages.  First, the haze that is commonly apparently from mid-morning on through dusk is invisible in the IR.  Secondly, excellent captures can be made just about anytime between 10:00 and 14:00, assuming that the cloud cover is minimal.  Finally, since all ‘good photographers’ know that you cannot make decent capture outside of the golden hours, you will have what may normally be crowded locations all to yourself.

The images in this entry were all recorded from points all the Jackson Hole Highway – see the March 7, 2011 entry for more on this most excellent road.  Captures were recorded between 11:30 and 12:45 on August 8, 2010, using the Nikon D200 converted to IR , and the AF-S 16-85mm f/3.5-5.6G VR IF-ED lens at focal lengths of between 35mm and 50mm .  The IR conversion was made by Life Pixel, using their Deep BW IR option – equivalent to Wratten 830nm filter.  Images processed using Nik SIlver Efex Pro 2 and Adobe Photoshop CS5.
