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
A pretty good argument for using ProPhoto RGB as your working color space
Photographers discovered 20 years ago that sRGB is a really bad color space for professional photography. So we all changed to Adobe RGB 1998. The reasons for doing so are important: Adobe RGB has a larger overall gamut, and conversion … Continue reading
Bavaria has castles! I have photos.
In my home county in California we have a famous castle, one built by newspaper magnate William Randolph Hearst in the early 20th century. Called Hearst Castle, it is a tourist mecca, visited annually by several million people. The castle … 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

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
Van Gogh’s Père Tanguy in perspective
Museums often have no-photography rules, depending on their policy about allowing visitors to take photos, or the legal arrangements they have with art owners, copyright holders and other things that go beyond my pay grade. In the Galleria dell’Accademia in Florence, … Continue reading
The Bishop Peak Portrait Project is very nearly up!
For the next five months I’ll be living in Munich and teaching at the Munich University of Applied Sciences. I arrived here a week ago and I had my first classes this week. But, last week, before leaving San Luis … Continue reading
Once a bitmap, always a bitmap
In my recent series of blogs about reproducing line art from 19th century copper engravings (and similar line art) using modern digital technologies I showed how scanning as grayscale and converting to bitmap format (with the 50 percent dither option) … Continue reading
