The Tetons Beyond 830 nm

The Teton Range Beyond 830 nm

The images above and below were recorded at Antelope Flats.  The image above was recorded at 15:00 MDT on June 8, 2013 using the Nikon D200 converted to the Wratten 830nm filter cutoff by LifePixel Inc (aka the D200IR)**.  The lens used was the old but reliable AF-S Nikkor 18-70mm f/3.5-f/4.5G at 27mm.  Exposure was f/16 and 1/80s, ISO 100.  The image below was shot with the same setup, but with the lens at 50mm, and an exposure of f/16.0 and 1/30s, ISO 100.

The image above was recorded at 15:00 MDT on June 8, 2013 using the Nikon D200IR and the 18-70mm lens at 27mm.  Exposure was f/16 and 1/10s, ISO 100.  This shot was taken at the famous Snake River Overlook.

**There are many IR conversion options, and the technical details are well-detailed on the LifePixel website.  Although the lower wave length cutoff filters, i.e., color IR filters, produce interesting images, I prefer the deep saturation and contrast generated by the ‘Deep BW IR’ filter, e.g, the 830nm cutoff filter.

Grand Teton Diary: June 1-2, 2012

Early summer may be our favorite time to visit Grand Teton National Park.  There will be snow high on the Tetons through the end of June, which makes for an excellent contrast element to the complex rock formations.  The weather is fairly reliable, although as a few of these images will confirm, there is a enough instability to generate some interesting cloud formations.  Finally, we tend to spend most of the spring in the YNP, and have to delay a visit to GRTE (pronounced Gertie…) until early June.

Our favorite place to stay is at Jackson Lake Lodge.  It is a bit quieter here than at Colter Bay, certainly much quieter than at the Moose Junction area.  The lodge proper houses the registration office, gift shops, and restaurants, but few rooms.  A spectacular view may be had from the east side of the lodge, where windows rising from floor to the top of the peaked ceiling provide a lovely frame for the view of the Tetons across Willow Flats.  The guest rooms are laid out in blocks southwest of the lodge.  Many of these rooms have views of the Tetons, some of them spectacularly so.

A big advantage of staying at the Jackson Lake Lodge is that it is only a few minutes from Oxbow Bend, making it relatively easy to photograph Mount Moran from across the Oxbow Bend of Snake River at dawn.  The image above was recorded at 08:35 MDT (yeah, we arrived late the previous evening so the dawn thing was not happening) on June 1 , 2012, using the Nikon D800E and the AF-S NIKKOR 24-70mm f/2.8G ED lens at 70mm.  Exposure was f/11.0 and 1/160s, ISO 100 (base).

From Oxbow Bend, the most compelling route to explore the park runs N/S along Highway 89 (and concurrently, Highways 191 & 287).  Traveling south from the Oxbow Bend, you will first run east to the Moran Entrance, and then track dead south.  The first major stop along Highway 89 will be the Cunningham Cabin area.  The site consists of two buildings located on several acres.   A buck-and-rail fence runs east-west along the southern edge of the site.  As you can see in the image below, the fence provides a nice foreground element to the image of the Tetons.

The name buck-and-rail derives from the characteristic X-shaped ‘crossbuck’ or ‘buck’ and long horizontal sections or ‘rails’.  Buck-and-rail fences are common throughout this part of the country.  The popularity of the style derives primarily from the fact that no post holes need to be dug.  The abundance of Lodgepole Pine trees in the region, which grow to produce specimens with trunks that are narrow and straight, insures a ready source of fence stock.

The image above was recorded just east of the cabin at 12:47 MDT on June 1, 2012, using the D800E and the 24-70mm lens at 70mm.  Exposure was f/11.0 and 1/160s, ISO 100 (+0.33EV, corrected in post-processing).

An observation I have made on a number of previous occasions is that infrared imaging provides a very entertaining option for the motivated photographer.  Early summer in Gertie presents many such opportunities.  The image above was recorded at 11:46 on June 1, 2012, using the Nikon D200IR (converted to 830nm cutoff by LifePixel Inc) and the AF-S DX Zoom-NIKKOR 18-70mm f/3.5-4.5G IF-ED  lens at 60mm (90mm effective in FX).  Exposure was f/16.0 and 1/10, ISO 100.

Retracing our steps brings us back to the Cunningham Cabin area at around noon:30.  The image above was recorded using the D200IR and the 18-70mm lens at 40mm (60mm effective in FX).  Exposure was f/14.0 and 1/10, ISO 100.

The image above was recorded using the D200IR and the  18-70mm lens at 75mm (90mm effective in FX).  Exposure was f/16.0 and 1/10, ISO 100.

Traveling further south brings us to the famous Snake River Overlook (below).  Many have noted, some with lament, that the trees have grown tall since Ansel Adams made his famous image here in 1942.  I disagree with those that find the changes problematical, and suggest that a well-made image from here (today) can be just as compelling as those made by the master 70 years ago.

The image above was recorded at 13:09 on June 1, 2012, using the D200IR and the 18-70mm lens at 57mm (90mm effective in FX).  Exposure was f/16.0 and 1/10, ISO 100.

The region south and east of the Snake River Overlook is known as Antelope Flats.  We have not seen many antelope (pronghorn) around, but the area is very popular with bison, and we have seen moose near Ditch Creek.  A short drive east along Antelope Flats Road brings you to Mormon Row and the famous Moulton Barn shown below.  The gambrel-style barn structure has a timelessness to it that many find interesting – many are surprised to learn that the barn was used by the Moulton family until 1945.

Image above recorded at 14:07 MDT on June 1, 2012, using the D800E and the 24-70mm lens at 55mm.  Exposure was f/11.0 and 1/125s, ISO 100.

In early summer Antelope Flats is decorated by brilliant yellow Mule’s Ears (Wyethia).  The image above was recorded at 14:24 MDT on June 1, 2012, using the D800E and the 24-70mm lens at 42mm.  Exposure was f/5.6 and 1/2000s, ISO 400. Handheld.

After passing through Moose Junction we headed back north along the Teton Park Road, which tracks much closer to the Teton Range.  Just north of the Taggart Lake Trailhead, we found that the River Road was open.  On previous visits, the road has been closed.  There are a number of interesting things to see along the River Road, but it is the unique views of the Snake River that I find most compelling.  Below we find the HP; with her ever-present field glasses, along the western bank of the Snake.

Image above recorded at 16:27 MDT on June 1, 2012, using the D800E and the 24-70mm lens at 32mm.  Exposure was f/8.0 and 1/320s, ISO 100.  Handheld.

Having recovered from a previous late arrival on the evening of May 31, we were ready for an early start on June 2.  The images above and below of the Tetons looking across Willow Flats we made at 05:44 MDT (above) and 05:52 MDT (below) using  theD800E and the 24-70mm lens at 70mm.  Exposures were f/11.0 and 1/10s (above) and 1/15 (below), ISO 100 (-2.33 EV).

The image above was recorded at 05:52 MDT on June 2, 2012, using the D800E and the 24-70mm f/2.8G ED lens at 70mm.  Exposure was f/11.0 and 1/15s, ISO 100 (-2.33 EV).

Quite often, during a visit to Gertie, we will make a dash up to The Stone.  A visit to Artist’s Point overlooking Lower Falls and the Grand Canyon of the Yellowstone River, shown below, is a favorite spot.  I have a few other things to share about our visit to YNP on June 2, but that will have to wait for a future entry.

Image above recorded at 09:24 MDT on June 2, 2012, using the Nikon D800E, and the AF-S NIKKOR 24-70mm f/2.8G ED lens at 70mm.  Exposure was f/11.0 and 1/125s, ISO 100.

Finally, we returned to Willow Flats in time to catch the sun setting over the Teton Range.  When the atmospherics are right, as shown here, the back-lighting of the Tetons can be properly dramatic.  Image above recorded at 20:48 MDT on June 2, 2012, using the D800E and the 24-70mm f/2.8G ED lens at 40mm.  Exposure was f/8.0 and 1/13s, ISO 100 (-2.0 EV).

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.
