FIGURE 3.1

The Paul-Acres Camera

The first version of this practical camera for taking motion pictures was apparently completed by February 1895. Among other items, Paul improved upon an original design by Acres that called for a crude clamping device to ensure intermittent movement. Like the Edison kinetoscope, this camera took pictures at a rate of 40 per second. When films shot with it were later projected on Paulís theatrograph (see Figure 3.6), which projected 16 images per second, the resulting effect was that of slow motion. Paul corrected the problem with a new camera that he built later in 1896.
