blendtypes

Blend types refer to the various methods used to combine two or more images or layers in digital graphics and video editing. These techniques are fundamental in creating composite images, special effects, and visual effects. The most common blend types include:

Additive blending combines the pixel values of two layers by adding them together. This technique is often used to create glowing or light effects, as it increases the brightness of the overlapping areas.

Subtractive blending subtracts the pixel values of the top layer from the bottom layer. This method is useful for creating shadows or darkening effects, as it decreases the brightness of the overlapping areas.

Multiply blending multiplies the pixel values of the two layers. This technique is often used to create shadows or darken images, as it reduces the brightness of the overlapping areas.

Screen blending inverts the multiply blending effect by inverting the pixel values before multiplying and then inverting the result again. This method is useful for creating highlights or lightening effects, as it increases the brightness of the overlapping areas.

Overlay blending combines the multiply and screen blending effects. It multiplies or screens the pixel values based on the base color. This technique is often used to create a more natural-looking blend, as it preserves the highlights and shadows of the original images.

Blend types can be adjusted using various parameters, such as opacity and blend mode, to achieve the desired visual effect. Understanding and utilizing different blend types is essential for creating compelling visual content in digital media.
