Of course, black will not result in any change when using the Screen mode. The resultant image is one that is brighter than either of the source layers. It multiplies the inverse of the blend layer’s color values by the inverse of the base layer’s color values. However, the Screen mode works completely opposite to the multiply blend mode. Screen, like Multiply, is popular and used frequently in the edit bay. Screen Screen produces a lighter image by multiplying the inverse of the color information in the blend layer by that of the base layer. It also helps in compositing shadows, as well as deep colors to a shot. Apply this analogy to color values and the result is a lower color value and therefore darker.Ī blend between two video clips doesn’t tax the processing power of a computer and provides a quick way to develop a unique look.įor the video editor, Multiply is useful in adding texture to footage and casting vignettes on the screen. When a fraction less than one is multiplied by another fraction, which is less than one, the result is a lower number. It helps to think of a pixel’s color value as a fraction on a scale from zero to one. The name multiply can add to some confusion when deducting how this operation works because multiplication would indicate an increase in value, and thus lighter colors. It multiples the color information of the blend layer with the color information of the base layer, this results in darker values except for where there is pure white in the image. Multiply is one of the most popular and widely used blending modes. Multiply Multiply does just that - it multiplies the color information of the blend layer by that of the base layer, producing darker colors overall. The resultant image looks like it is dithered with noticeable digital artifacts. With Dissolve, random pixels from the blend layer are replaced with pixels from the base layer. The Dissolve mode is more of a random operation than it is a composited blend. Dissolve Dissolve samples random pixels from both the blend and base layers. Otherwise the image will look the same, whether it is on top of another image or isolated by itself. A composite only happens when there is variable transparency applied to the top, blend layer. The Normal mode is the default blend mode for any image. In each case, the image on the top will be the top blend layer while the gradient on the bottom serves as the bottom base layer.

To illustrate the difference between the various blending modes, we’ll use the adjacent images to create a series of composites.
This produces a resultant composite image. Each blend mode applies its unique mathematical operation to the color information of each pixel in the blend layer and combines it with color information of each corresponding pixel in the base layer.
The bottom layer is the base layer while the top layer is the blend layer. There are normally two images layered together to make a composite with blending modes. What are Blending Modes?īlending modes are a way to use the color information in two digital images to create a composite image. The ability of blending modes to composite two or more images into a resultant combined image proved to be desirable and were quickly implemented into other imaging software, such as the standard video editing suite. Video editors are used to seeing blending modes, whether they wield them when necessary or stumble across them, never knowing what they’ll get.īlending modes are rooted in the history of darkroom photography and were adopted into and expanded upon by digital imaging programs, such as Adobe Photoshop. One artifact that has existed for years inside of video editing programs is blending modes. Travellers of these worlds were bound to find artifacts of the other arts as the crafts of imagery converged and technology allowed the magic from one to transfer to another. Graphic design was separate from photography, which although centered on the camera, was vastly different than videography and animation was something left for creatives from another realm. The world of image creation used to be siloed into different media.
