AppleScript solves my grid mask challenge in Adobe Photoshop
I pride myself on being a competent user of Adobe Photoshop. I know how to make my photos look good by sliding sliders and pushing buttons and applying filters and adding Layer Effects and all sorts of visual things. Occasionally I need … Continue reading
Illustrator graphs show me how my solar system is working
Greetings Blognosticator readers! I (sort of) apologize for my long absence from this blog. I retired from my teaching position at Cal Poly in mid-June, and have been relaxing since then by not contributing essays to this forum. Instead, I … Continue reading
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

Digital panoramic photography
This is part four of my series on panoramic photography and cameras. In the first episode I wrote about rotating panoramic cameras that used rolls of film. As the camera turns, the film rolls past a vertical slit aperture in … 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
