Advanced blending modes

Have you ever wished you could apply a layer blending mode only to a range of the image without having to use a layer mask? So you’re in luck, in PhotoShop layer properties you have the right tool for this process.

Lost at the bottom of the layer properties window is located the advanced blending mode which varies images’s opacity varies pixel by pixel depending on the color of the pixels in the bottom layer.

This advanced blending mode works similarly that the opacity control except that instead of affecting the entire picture it works isolation each one of the channels. Therefore, the possible merging options depend directly on the color space in which we are working. Apart from the workspace’s channels it allows us to affect gray color.

This image from SBK will serve to illustrate how to operate with advanced blending modes.

First layer has been doubled and then applied neon light effect.

In this first example it has been melted the neon layer effect with the original layer using the range of grays. The first pair of controllers affecting the current layer and the second ones the underlying layer. In the image can be seen that by varying the opacity of the upper layer, the underlying image will appear above. In the example, using the vector of the right, first thing that begins showed are the darker tones, that means, the pixels are made transparent with the darker tonal ranges. If it has been used the left vector first transparent pixels have been made of the lighter tonal ranges.

Each controller has two possible settings that vary the output level by moving each one separately (press ALT) this easely smooths the merging layer, as shown in the image.

By varying the controller of the underlying layer what is achieved is to bring its color up, by changing the opacity of the current layer.

In the last image is possible to observe this transition in the red channel. The result of the operation could be expressed as follows:

If the pixel of the underlying layer has a high value red its corresponding pixel in the current layer gets transparent

If it had been used the right vector it would means:

If the pixel of the underlying layer has a low red its corresponding pixel in the current layer becomes transparent
