Monivärikuvaus

Monivärikuvaus refers to the process of capturing and reproducing images using multiple colors. Traditionally, this has involved separating an image into its primary color components, typically red, green, and blue, or cyan, magenta, and yellow. Each of these color separations is then recorded on a separate medium, such as a photographic plate or a digital sensor. When these separated color images are combined or overlaid in the correct proportions, they reconstruct the original full-color image.

In traditional photography, this was achieved through various multi-layer films or by using separate filters during exposure. For printing, the process involves using different inks or dyes for each color separation, which are then printed in sequence onto paper. The accurate registration and blending of these inks are crucial for a faithful color reproduction.

Digital monivärikuvaus is now the dominant form, utilizing digital sensors that capture light across different wavelengths, often processed to create RGB or CMYK data. Image editing software then allows for manipulation and printing of these color components. The principle remains the same: breaking down a scene into its constituent colors and then recombining them to create a visual representation. This technique is fundamental to almost all forms of color imaging, from photography and film to printing and digital displays.
