Glacier National Park Beyond 830nm

It’s a long way from anywhere to Glacier National Park.  From Salt Lake City to Apgar, MT, it is about 650 miles, 11 hours travel time.  It’s about the same story to go from Portland to Apgar.  The distance is a bit shorter from Seattle to Apgar, about 550 miles, which can be done in about 9 hours.  Denver to Apgar is 970 miles, which will take about 15 hours.  Like I said, a long way from anywhere.  The good news is (obviously) that the long distances from large metro areas keeps the number of visitors down, but make no mistake, it can get remarkably crowded at times.

Naturally, once you get to the Park, you want to maximize the experience.  For the photographer-expeditionary, this means getting up at dawn and not quitting until after the sunset.  For many though, there is a big gap from about 11am until about 4 or 5 in the afternoon.  Some (slackers) use this time for siesta, others use the time to get into position for the afteroon or sunset.  In my view the very best way to spend the noonish hours is to keep right on shooting.

One way to extend time behind the lens will be to to push conventional photography beyond conventional (golden hour) time limits.  I’ve written a bit about the myth of the golden hour from time to time.  If you are willing to invest the time it takes to properly process such images, this can be an effective approach.  Under the right conidtions and with the proper gear, a most excellent option is to shoot in the near infrared (near-IR).  The best way, and in my opinion the only reasonable way to shoot the near-IR is to get hold of a DSLR camera in which has the anti-aliasing filter replaced by a near-IR cutoff filter.  There are several groups that will do this – I have used and can recommend LifePixel out of Mukilteo, WA.  Folks seem to like the mods done by LDP LLC aka MaxMax as well.  Anyway, I had a Nikon D200 modified to the Life-Pixel Deep BW IR option, which is equivalent in the old-tongue to a Wratten 830nm filter set up.  The Deep BW IR provides the richest, deepest tones available in an IR modification.

Quality near-IR capture requires the presence of direct sunlight overhead.  Clouds on the horizon add essential drama to these shots, and without clouds the sky goes nearly to black.  Of course given the right sort of foreground elements, e.g., foliage, this can work well.  If clouds block the sun overhead however, the resulting image will lack the contrast that one is generally hoping for in the capture.

The first four images in this entry were recorded on at around 14:00 MDT on July 23, 2011 using the Nikon D200IR and the AF-S DX NIKKOR 16-85mm f/3.5-5.6G ED VR at f/11 or f/16.  I generally like to shoot a bit closer to noon to get the most intense contrast, but things seemed to work out well here.

Although light is metered through the lens in an IR-modified camera, the meter is measuring the visible light intensity, whereas with the 830nm cutoff we are looking at something else.  Fortunately, the intensity of the near-IR light is proportional to the visible, and simply requires that you dial extra exposure to compensate (about +3.0 EV in my case).  In practice I bracket the exposure +/- 1.0 EV in 1/3 f-stop increments.

The subject of the first three images was Saint Mary Lake, while the forth image (above) was made near Lake Sherburne.

The images above as well as the following two images were made at about 11:00 MDT on July 24, 2011, near Logan Pass.  No clouds, but plenty of dramatic contrast.

 The image below was recorded at noon on July 24, 2011, at Sun Point near the western edge of Saint Mary Lake.

The final two images were recorded along the shore of Lake Sherburne at around 13:30 MDT.

Images were converted using ACR version 6.5 or 6.6 to set WB and exposure.  The bulk of the processing was conducted using Nik Silver Efex Pro 2, based on a variation of the High Structure – Harsh preset.  Additional processing was applied using Color Efex Pro 4.  Capture, creative, and output sharpening was applied using Photokit Sharpener 2.0

Did you catch the HP in the first image?  Yep, look again.

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.

Mesa Arch

Mesa Arch is located in the Island in the Sky district of Canyonlands NP.  The arch is accessible via a short, relatively flat 0.5 mile hike from the parking lot adjacent to SR313.  The parking lot is near the junction of roads leading northwest to Upheavel Dome and south towards Grand View Point Overlook, about ten miles inside the park on SR313.  Mesa Arch is easily one of the most photographed natural arches in the world.  Based on our three or four visits to the arch, I’d estimate that your mean time alone here is perhaps two minutes – no kidding.  If you want to photograph Mesa Arch without also including your fellow beings (who are posing for their own photos), you have to be patient and act fast.  The classic image is of the arch at dawn, with light streaming in from underneath.  There are hundreds of virtually identical images posted on the web.  All quite serviceable, but nevertheless subtle variations on a single theme.  Unlike the many relatively smooth forms found in Arches NP, Mesa Arch has a distinctly rough surface, and this is what I wanted to emphasize in this set of images.

Mesa ArchThe IR image above, looking west through the arch to the La Sal Mountains and Shafer Basin was recorded on February 15, 2009 at around 15:00 MST using the Nikon D200IR (see the March 6, 2009 entry for details) and the AF-S  DX Zoom NIKKOR 12-24mm f/4 IF-ED lens at 18mm.  Exposure was f/16 at 1/20s, ISO 100.

The arch is perched on the edge of the mesa, overlooking Buck Canyon about 1000 feet below.  As I’ve mentioned in a previous entry, if arches earned their name from their function, this one would be named ‘walked-on arch’.

Mesa ArchThe image above; looking west-southwest, was recorded using the Nikon D200IR and the AF-S  DX Zoom NIKKOR 12-24mm f/4 IF-ED lens at 12mm.  Exposure was f/16 at 1/25s, ISO 100.  The image below is identical the one shown above, apart from application of a coffee tone.  Toning was applied using Nik Silver Efex Pro.  I am partial to the coffee-toned image, but wonder whether it might be over-the-top.  Comments appreciated.
