The Importance of Grayscale and Luminance in Images
Grayscale images are not merely black and white. They are composed of various shades ranging from black to white. The information contained in these shades relates to luminance, which describes the amount of light that is emitted from, passed through, or reflected off an object.
Unlike brightness, which is subjective and can vary among individuals, luminance is measurable. This makes it a vital aspect of image quality and visibility. In fact, when we remove the color information from a standard image, it becomes grayscale or achromatic, which means it's without color. Yet, the image remains visible because the luminance information is still present.
On the contrary, if we delete the luminance information, we end up with an entirely black image with nothing left to see! This is why luminance and brightness are often considered more important than color information in an image. Our Grayscale PDF Tool leverages this principle to convert colored PDF documents into high-quality grayscale versions.
