Spelling Bee

I was walking toward the Graue Mill to explore the nearby trails. Along the way, I noticed this intriguing sign.

The spelling was correct on the other side.

Pullman Exploration

I've been rescanning a few images from a trip to the Pullman factory site - this is a mix of imagery from a large format camera, and a Leica IIIf. This opportunity was part of an excursion with members of the Midwest Large Format Asylum - http://www.midwestlargeformat.com

I hope to add an image of the Hotel Florence soon.

Composition, and cold weather

Several years ago I was intrigued by the long winter shadows at the historic Graue Mill, in Oak Brook Illinois. http://www.grauemill.org

I put a wide angle lens on a Hasselblad - the old 40mm C Distagon. A dark orange filter was placed up front, to enhance contrast. There was some Ilford HP5 film rolling around in my collection, so I loaded it up and drove to the mill.

It was brutally cold. After each exposure, the lens would stop down, but did not return to its wide open f4 aperture. I had to manually open it up in order to compose the rest of the images.

The equivalent view of this lens in 35mm terms, is in the range of 25mm. With a very few steps, the image composition changed radically.

Batteries can also be problematic in cold weather. I've used a motorized Hasselblad a few times, and the internal battery failed quickly when used during a 15 degree day. I rigged up a small 6 volt lead-acid battery, kept it in a pocket inside my coat, and ran a wire to the camera. This worked well. Always carry extra batteries.

The Graue Mill is a favorite location of mine for photography. There are scenic trails through the adjoining natural area, and numerous events are held throughout the year.

Abstraction of an abstraction

Looking through some older negatives, I found misplaced images that I thought had been lost. I had a low resolution jpeg, and a left/right pair from a flatbed scanner that I could stitch together for a reasonable version for the web. I'd sent three negatives to a lab that provides high resolution drum scans, so that I could print large versions of the images for display in juried art shows. At some point, cleaning my desk, I managed to misplace the DVD, and the negatives...

In 2005 - 2007, I had the opportunity to exhibit several of my large anamorphic prints in the juried Around the Coyote Fall Arts Festival. Hundreds of artists filled the Flatiron Building and adjacent commercial locations in Wicker Park.



I was intrigued with the possibility of creating large versions of the imagery, since details in smaller prints I had made with inexpensive consumer scanners and printers could not produce the desired results.

The negatives produced by the Omniscope camera could be difficult to work with. One issue is the variation of the exposure. Across the face of the film, there is roughly 1.5 stops gradient between the edges of the film. This will be explained in a separate post on the camera later. The negatives are from medium format film, and approximate the 6cm by 17cm format.

Once scanned, the high-resolution images were printed, using a LightJet printer that fires lasers to expose either Kodak Endura or Fuji Crystal Archive photographic paper. For each show, I had to produce two or more new prints. Three candidates were missing, and I was stuck using the consumer-grade scanner. The prints from the LightJet were acceptable, yet didn't have the look I'd hoped for.

Pinhole images can be surprisingly sharp. They are diffuse by nature. This characteristic, distortion, or whatever you prefer to call it, can be used in creative ways like any other optical property. Control of the depth of field  is commonly used to emphasize a face in portraiture, as the eye is drawn to the detailed parts of an image. Another characteristic of pinhole imagery is a near-infinite depth of field - in relative, practical terms. My Nikkor-M 300mm large format lens has an aperture ranging from f9 to f128. At f128, the lens is approaching the relative size of a pinhole aperture, and has an amazing depth of field. I'll post an image using the lens at f128... when I find it... showing a fence with adequate focus at about three feet from the lens, with a building in sharp focus about a half-mile away.

Here are the three 'lost' images. They are not particularly impressive in this small format for the web, so you'll have to imagine the detail and subtle nuances of a high resolution print at about 40 inches wide. The original files are scanned at 300 dpi with an image width of 65 inches. Imagine that on display - I may try one that large. I will not pay for the framing, however... I'll settle for a few tacks.

Abstraction of the Abstraction

Under the Cloud Gate sculpture, by Anish Kapoor, is the omphalos, a highly polished concave chamber that distorts and reflects. It looks like this...

I wondered what this distorted world would look like when imaged with the Omniscope. An abstraction of an abstraction...

This was taken after the seams were polished. The camera was on a low tripod near one end, where I had to stoop low enough to stay out of the way. Tripods are not welcome under the sculpture - I happened by when it wasn't noticed, or they didn't care since I was well out of the way.
