Running the five-color
Pearl press postcard
Last year I began the restoration of an 1895 Pearl press, a treadle-powered letterpress that was donated to the Cal Poly Shakespeare Press Museum. That press was a rusty machine when we took delivery of it. I took it to … Continue reading
Reminiscences of a prepress guy
I am an old prepress guy. I owned one of the first PostScript service bureaus in the U.S. I was there at the beginning. It was painful, but overall it was a great business. We had been traditional typographers, and … Continue reading
My new Canon EOS R mirrorless camera
and a new world of high ISO shooting
I was excited when Canon and Nikon both announced their mirrorless pro (or semi-pro) cameras last fall. The time had come. Sony has been in the market for three generations now, and Canon had made a few attempts (EOS M, … Continue reading
The case for using DNG as your primary file type
I have files created by a Kodak-branded, Canon digital camera from this century that can no longer be read. This is my second case of file obsolescence; the first being Kodak Photo CD files that cannot be read by any … Continue reading

Spinning time into gold with slit-scan images
My blog of day before yesterday told of the process of recording things that move in front of a photo-finish camera (also called a slit-scan camera). This is an S-Bahn train coming into the station. Its speed was constant, except … Continue reading
Difference of opinion makes a horse race
In a recent blog I introduced you to the rotating panoramic camera, a complex mechanical device dating from the early 20th century. The heart of that camera is the roll of film, moving at a constant speed through the camera, … Continue reading
Panoramic cameras and images, Part I
The first true panoramic camera was patented by William J. Johnston in 1904. Century Camera Company brought that camera to market in 1905 as the Century Cirkut Camera. The company later became a part of the Eastman Kodak Company, which … Continue reading
Street Art provides an opportunity
for repositioned panoramas
My wife and I traveled today to see a neighborhood in Munich that is famous for its street art. It’s called the Tumblingerstraße area, and it features some very sophisticated works of graffiti – much better than graffiti – that … Continue reading
