H-Number
H-Number, also known as the Hazen Scale, is a method for rating the color sensitivity of photographic films. It was developed by William Eugene Hazen in the early 20th century and has since become one of the most widely used methods for comparing the color sensitivity of different types of photographic film. The scale assigns a unique number to each film type based on its sensitivity to light, with higher numbers indicating greater sensitivity to color. One of the key advantages of the H-Number system is its simplicity and consistency. By providing a standardized way to rate the color sensitivity of different films, it allows photographers to make informed decisions about which type of film to use for a given project. This can be especially important in situations where color accuracy is critical, such as in commercial or scientific photography. In addition to its use in film photography, the H-Number system has also found applications in other areas of color measurement and analysis. For example, it is sometimes used to rate the color sensitivity of digital cameras or other imaging devices, or to compare the color accuracy of different types of display screens. Overall, the H-Number system remains an important tool for anyone involved in color photography or color analysis. Its simplicity and consistency make it a valuable resource for photographers, scientists, and engineers alike.

H-Number
H-Number, or the Hazen Scale, is one of the oldest and best-known methods for rating the color sensitivity of photographic films. Developed by William Eugene Hazen in the early twentieth century, the scale assigns each film type a unique number based on its sensitivity to light. Hazen's scale is an invaluable tool for photographers, as it provides a simple and consistent way to compare the color sensitivity of different types of photographic film. Important works by H-Number include his series of papers on photographic sensitometry, published as part of his doctoral thesis, and his work on the measurement of color sensitivity.
