Pinnacle Studio: Understanding Color Correction

Color correction is one of the final stages of the post production process. To understand how color correction works, you need to understand how a digital image is created.

Digital Image Creation

A digital image begins with the lens. Light enters the lens and reflects the image onto an image sensor. The sensor then converts the image into a digital file by breaking it down into pixels. Each pixel is a solid color created by a combination of the colors red, green and blue. These pixels all form together to create your image.

Now the image is dependent on light, and light comes in different color varieties. Your eye might be able to compensate for it automatically, but your camera does not, which is why you need to white balance when shooting. However, most images are not perfectly color balanced when shooting, and usually require some form of color correction.

Using Color Correction

So when you color correct with your editing program, you are manipulating the overall RGB scheme of an image. If the image seems to warm, then you decrease the red value and raise the blue. If it's too cool, then decrease the blue and increase the red. It's a process that might seem tedious, but it has huge influence over the quality of your final edit.
