Linear Dodge

Linear Dodge also belongs to the Lighten group of blending modes; it will always lighten the picture and blending with black has no effect. Linear Dodge can be seen as a combination of Color Dodge and Screen, but it's a more powerful blending mode than either. Like Color Dodge, Linear Dodge can clip highlights, which does not happen with Screen, but Linear Dodge differs from Color Dodge in that it lightens black.

Linear Dodge inspects each color channel and brightens the base color to reflect the blend color by increasing the brightness. Does this definition sound familiar? If so, that's because Linear Dodge's definition is the exact opposite of Linear Burn (see pages 32-33). While Linear Dodge lightens the base to reflect the blend color by increasing brightness, Linear Burn darkens the base by decreasing brightness.

Using Linear Dodge

You can produce interesting results by inverting the blend layer and applying small amounts of Gaussian blur At first, the image is completely white, but as you increase the Gaussian radius, you will see a line drawing begin to emerge In this picture of the girl, a little blur washes out the image, around 10-15 produces a weak line drawing, while pushing the radius up to around 25 produces the most balanced effect

Notice how Linear Dodge produces a brighter result than Color Dodge, but also notice how Linear Dodge, unlike Color Dodge, lightens the blacks.

Applying Linear Dodge and Gaussian blur with a radius of 25 to an inverted image produces a balanced combination between a line drawing and a bleached photograph.

Here, I applied blur to the blend layer before inverting it. This isn't really a good idea as I can't see my final result. So, try to change the blending mode and do any inversion before applying blur.

A smaller amount of blur (here, I've used a value of 10) produces a weak line drawing without the need for filters.
