The Negative Image Calculator is a powerful tool that allows you to effortlessly transform your images into stunning photo negatives. By simply loading an image into the calculator, it automatically generates a negative version by inverting the RGB colors of the original image. The RGB color model represents colors using three channels: red, green, and blue. With this calculator, you have the flexibility to choose which color channels to invert, enabling you to create custom negative effects. Whether you want to invert all three channels or selectively invert specific colors, such as red or green, the Negative Image Calculator provides you with the creative freedom to achieve the desired result.
Inverting image colors
In the RBG model, each pixel of the image is represented by three numbers (R, G, B), each of them represents the model channel: R - for the red channel, G - for the green channel, B - for the blue channel. Each number lies in the range 0 - 255. This model is called an additive color model, since a particular color is produced by adding three primary colors to the black color (0, 0, 0). The maximum value - (255, 255, 255) represents a white color. The calculator above simply inverts all pixels of the image using the formula (255-R, 255-G, 255-B).
