FILM 1400 Chapter Week 1 (2-48): Reading Notes - Week 1
Document Summary
A photographically based film is a ribbon of still images. The most common shooting rate is 24 frames per second. When the film strip first emerges from the camera, it is a negative, meaning the colours. In the 35mm format, film runs through the projector at 90 feet per minute and light values are the opposite of those in the original scene. Before the image can be projected, a positive print must be made. A professional digital motion picture camera functions in the same way as the 35mm camera. Digital cameras use a fixed sensor instead of film. The sensor is covered with a grid of millions of microscopic diodes (also known as photosites). Each of the diodes create pixels in the final image from the captured light. 720p images contain about 921,000 pixels, and 1080p images have nearly 2. 1 million.
