Color Management Can Be Easy
You are likely familiar with color management if you’ve spent time behind a camera or if you have invested a fair bit of your time in photography and videography. We often unconsciously perceive the absence of color management in everyday life. For example, we have all taken pictures, ordered prints and suddenly realized that they have a flaw, like a green cast. “That’s not what it looked like when I took the picture!” is the most common reaction. Nobody wants skin tones that remind them of zombies; certainly not in a professional environment, such as portrait and wedding photography. The process might seem daunting, but color management can be easy.
How does the color discrepancy between perception and prints arise?
To understand color management, you first need to take a closer look at the properties of light. White light consists of all of the colors of the visible spectrum. As the composition of colors changes, the color temperature changes. For instance, there are more red component parts in the evening sun than in the midday sun, where the colors have a much more balanced ratio. That means a white sheet of paper should have a reddish or neutral look at times, but that is not always the case.
What about people? The retina of the eye, which is quite comparable with the sensor of a camera, perceives these color differences and redirects these signals to the brain. The brain analyzes this data and completes a white balance based on previous sensory experience. As a result, the sheet of paper mentioned above would then appear white. This phenomenon is called color constancy.
People also perceive colors at different brightness. Our brains perceive an image that isn’t what exists in purely physical terms. This explains the green-tinged photo: it was probably taken in fluorescent light, and technical devices do not have the “brain power” to counteract this phenomenon.
Color management will solve this issue
To a certain extent, color management attempts to simulate the brain and corrects the raw data coming from the sensor in order to match the feeling of human perception more closely. Color management can do even more than just that. While a human being represents a closed system (more or less), where everything is finely tuned, this is not the case with modern technology. We combine input devices (camera, smartphone, etc.) and output devices (monitors, printers, etc.), without considering that each device has a wide range of capabilities to capture or play back colors. Different papers also have their own reflection properties when they’re printed. All devices must be compatible with each other to prevent any unpleasant surprises. This is why color management is necessary to achieve color consistency across devices and outputs.
