Dragon Spine Plaza Blanca New Mexico

DP2M0107_small2

Plaza Blanca is about one hour north of Santa Fe New Mexico by car, the last couple of miles is a dirt road. Spectacular rock formations can be found only a few hundred yards from the parking lot. I’d just started walking again after all the foot surgeries. This was taken with a paired Merrill Dp2 rig, on a sliding bar with about 8 inch stereo base. Then the image was transferred to Provia 100F by photographing a 4K screen.  (I describe the process in more detail in A28 folio notes). The developer was nearly exhausted and resulted in thick image with excessive contrast. I plan to send my film to Colorado lab in the future. There are lots of lovely digital images taken with this Foveon sensor camera (thanks to Boris Starosta for turning me on to the Merrill, he uses Merrills in his clear building series). The Foveon sensor records all RGB at each site in a ‘stack’ of sensors, so each color plane has all the full resolution, without interpolation since there is no Bayer filter.  I plan to upgrade to a 10 bit calibrated 4K screen, and eventually to an 8K screen for future digital to film experiments. I’ll also do some head-to-head tests going back to photograph the original subjects with digital and film (TL-120 and paired Mamiya 220 85 and 55 mm). I’m quite please with the Merrill sensor and lens, have the DP3 now too. Merrills are like using slower film cameras (usually want ASA at 100, tripod or good light for routine use), the slowness comes from the ‘thickness’ of the sensor, as light has to make it into the depths of the chip to provide the color information. But this lens is amazingly sharp.

Plaza Blanca is about one hour north of Santa Fe New Mexico by car, the last couple of miles is a dirt road. Spectacular rock formations can be found only a few hundred yards from the parking lot. The process used was the same as described for my image “Dragon Spine, Plaza Blanca”. This is one of the most beautiful sites in New Mexico for these odd eroded columns. These are a bit like the Tent Rocks (those are found an hour south of Santa Fe)…featuring a capstone protecting a column of softer material. Once the capstone is gone, the column will erode much faster. The area has changed in 10 years due to this process. If we ever have an NSA meeting in Santa Fe, this is one place to check out.

Native American Fetish Carving

This was done using a segmented mirror beam splitter box and a Sigma DP3 Merrill, with a front 3 diopter 72 mm diameter achromat for extra magnification. This little carving is only 1-1/4″ tall. I bought it from a Native American artist in Albuquerque from the State Fair 2006. I am looking for his name, but can’t find the receipt. If I find it I will update the post. This was done with a ring flash held off-camera (up and to the left). with a black velvet background. You can see the plastic base the carving was resting on. The lower left photo is the mirrorbox with the top off. The two first surface mirrors direct  the left and right halves of the camera frame along axes that give a 12 mm stereobase. Stereophotomaker corrects the slight keystone distortion nicely. Its made from 1/4″ ABS sheet solvent welded. The lower left face of the cube has a filter mount for screwing on AR filter and accessory lenses, the right face has a filter mount with adapter which accepts the Merrill DP3. Knobs allow the filter ring to be loosened to align the camera with horizontal plane of the macrobox. The macro mirrorbox is essentially treated as a “lens”. It hangs off the Merrill, which has a nice strong snoot. The right image shows the rig in use. The camera is mounted to the Benro Angel tripod with ARCA plate…from this vantage point, the mirrorbox is hidden by the flash power supply at the top. The accessoy lens and ring flash are on the left facing face of the cube. The subject here is a sprig of pinon stuck in an old 120 takeup spool. I’ll convert that image to film. Have some nice macro shots with this rig, just getting used to it.

ALSO: I will look at moving back or using focus stacking to increase DOF so the entire subject is sharp.

Alternate view of the Dragon Spine formation at Plaza Blanca, about one hour north of Santa Fe New Mexico by car, the last couple of miles is a dirt road. Process used is the same as for the Dragon Spine image (described in more detail there). The process for digital to film I described in my notes for A28 folio entries. This is the red channel only, spreading the histogram to result in maximum range from black to white (some of the streaks are from the JPG compression when I uploaded this image). The 16 bit Sigma Merrill image (which as 12 bits of useful range, padded to 16 bits) was processed in Corel PSP. This seems to introduce some aliasing in dark quarter-tones, next time I’ll use a 16 bit work flow. Most of the PSP workflow is 16 bit, but histogram manipulation seems to sometimes result in gaps in the color scale. This can be seen in the patterns in the sky, which was pushed down to make it dark. I could also try a red filter, but the red layer of the Merrill sensor is pretty good at that color separation. Perhaps a polarizer! Someone showed a film rig in 2012 (the MF SIG) at my first NSA and it had some square gradient filters, I could likely go that route (I think it was Bob Venezia). Close one eye and you could imagine this is a rider and a dragon, with a puff of smoke. In 3D that illusion is less convincing. Still, the figure to the lower right looks like and earnest fellow with a big nose and his muscular arms at his sides.

Iconic Images

Tent Rocks near Los Alamos

Well, this one is a bit different. It’s a hyper of a formation about 1/8 mile away taken using the Sony SLT 55 with a 100 mm prime macro lens. The images were acquired as part of a rapid burst from a moving car (I’d had foot surgery and my wife was driving me about). The spacing of the shots is around 100 feet. The white formations are about 30′ tall. This is a little known site near Los Alamos.

This was transferred to TL 120 using a “4K” screen. See “Camel Rock North Face” for the details of that process.

There is a very famous grouping of tent rocks, larger and more numerous, south of Santa Fe, which some of you may know of. They occur only in a few places, including outside of Istanbul, Turkey.

I’ll be heading out to Tent Rocks proper in the summer once things have solidified.

Overlook Park White Rock, New Mexico

This image was taken using cha cha and a single Sony SLT 55 with 35 mm Sony prime F1.8 lens. The focus of the infinity point was a bit soft so I used a bLind deconvolution filter (Lucy Richardson) to refocus. Then the images were transferred to TL 120 by photographing a quad UHD screen with custom color table.

This is one of my favorite sites, with many opportunities for interesting views depending on the time of day. This wa 2pm to a bit hard lighting. The figured rock in foreground was interesting. I was pleased that the raw format and transfer process kept the detail and color of the highlight on the rock. In the left distance is Black Mesa. I lived near there for 5 years in a former candle factory where I had a lot of my woodworking equipment. I’ve since sold that equipment.

When I take this site again, I’ll be using the tl120 directly with its 85 mm lenses

Camel Rock West Face

Sony slt 55a 35 mm prime. Cha-cha. October 10, 2013 10:35 am.

Used to be you could climb up on this until about 1970. There were actually two formations, one about 100 yards south. Some kids attached a rope and pulled it down with a pickup. So they put a fence around it.

This was transferred to TL 120 using a “4K” screen. See “Camel Rock North Face” for the details of that process.

Camel Rock North Face

 

I only recently discovered the MF stereo world thanks to Nik! the first I’d seen was at the 2012 NSA. Immediately after that I’ve had 7 foot surgeries and unable to use my TL 120 the way it was intended.  Determined to participate though, and once things are healed I’ll be getting out and composing directly to film. I realize one goal of this folio is to preserve the art of direct analog film photography, so my new entries are a bit of sacrilege. Since I’m a scientist I like to experiment. I have a bunch of 35 mm stereo and digital stereo photos. One question I wanted to answer empirically was: what would it look like to transfer images from my archive to medium format.

Inaugural Offerings

Geoffrey Waldo is our newest member in 2013. As you may be able to discern from his images, New Mexico is home.

I’ll go out on a limb and suggest these images were created with a TL120-1.
