Many thanks to Bruce Heller for the following explanation of how the DTB filters were used in the Technicolor dye transfer printing process: This blue filter is a sample of a rough ground Corning Glass DTB (Dark Theater Blue) filter. The example shown here has not been polished. These filters were used in the optical […]

As I was going through Jim Danforth’s equipment (he saved some very amazing things), I came across a pair of Technicolor prisms and a mysterious blue disc. One prism is from a 3-strip Technicolor camera, and the other prism looks suspiciously like the ones from the early 2-strip Technicolor cameras. There was also what, at

New arrivals! After many twists and turns with Fedex, we finally took delivery of equipment from the collection of Gunnar Blanke, a filmmaker from the Denver, CO area. Lots of neat stuff in this collection, including a Mitchell NC that was purchased by Lookout Mountain in 1959, two Mitchell GCs, an Akeley Gyro Head, a

Discussion on last week’s post made me think that this machine would be interesting to share. Back in the 80’s I built several single frame rear process projectors like the one pictured here. These projectors were used mainly to create composites of live action photography and matte paintings. Matte painting composites are an art form

In 1920, Bell & Howell introduced the Cinemotor, a revolutionary electric motor drive for their model 2709 motion picture camera.

For its

In the days of yore, back when I was shooting movies with Mitchell and Bell & Howell cameras, we often struggled with getting leather belts spliced together so they ran quietly and smoothly. Several of the assistant cameramen I worked with had a bag full of pieces that they would use to splice belts together.

We had so many interesting comments on last week’s trip down memory lane, I thought I would show another interesting solution to a problem we ran into while shooting space ships. Budget always being a problem, I had to devise a way to get close enough to the miniatures to give the illusion of the

A trip down memory lane . . . The movie industry always calls for unique solutions to unique problems. Many of us without the budget to build a Dykstraflex needed a device that would allow our cameras to be focused by computer control and hold the camera at nodal point. To solve this problem, I

Over the years, I have collected numerous Unit I shuttle camera and projector movements. I used these movements to build animation cameras, optical printers, and rotoscope stands. The first camera I remember using that featured a Unit I shuttle was a Bell & Howell 2709. Developed by Albert S. Howell and patented in 1912, the

Accessory Kit for a Mitchell Standard 35mm motion picture camera. These accessory kits were the best friend of cameraman, as they contained nearly everything you would need to shoot a movie! This very gently used example is is in remarkably clean condition with very few signs of use. A fantastic collectible!
