This photographic film captures images by recording the inverse of the colors and brightness values of the scene. Light-sensitive layers of the film react to different colors of light, creating a latent image that is then chemically developed into a visible negative. For example, areas exposed to bright red light appear cyan in the developed negative, while dark areas appear clear or slightly tinted.

This medium offered a versatile and affordable way to capture images in color for much of the 20th century. Its widespread adoption democratized photography, allowing more people to document their lives and the world around them in vibrant hues. The development process, which transforms the latent image into a viewable negative, also allowed for adjustments in color and exposure, affording a degree of creative control in the final print. This paved the way for countless iconic photographs and home movies, preserving memories and historical moments alike.

9+ RGB Light Wires: Positive & Negative Color Codes

Standard RGB LED strips typically use a four-wire configuration. Red, green, and blue represent the individual color channels, while the fourth wire provides a common ground or positive voltage. While the color coding for the individual red, green, and blue channels is generally consistent (red for red, green for green, and blue for blue), the fourth wire can vary. Often black or white designates ground, while red, white, or even blue can represent the positive voltage line. Consulting the manufacturer’s documentation is crucial to confirm the specific wiring for a given LED strip.

Correctly identifying and connecting these wires is essential for proper functionality and safety. Miswiring can lead to malfunctioning lights, damage to the LEDs, or even electrical hazards. Understanding this wiring configuration allows for proper integration with controllers, power supplies, and other components within lighting systems, enabling a wide range of dynamic color effects and precise control over illumination.
