Blending modes that lighten the image.
Similar to Divide. Inverts the top layer, and divides the lower layer by the inverted top layer. This results in a image with emphasized highlights, like Dodging would do in traditional darkroom photography.
Outputs the upper layer as power of the lower layer.
Similar to Overlay. A combination of the Multiply and Screen blending modes, switching between both at a middle-lightness.
Hard light checks if the color on the upperlayer has a lightness above 0.5. Unlike overlay, if the pixel is lighter than 0.5, it is blended like in Multiply mode, if not the pixel is blended like in Screen mode.
Effectively, this decreases contrast.
With the darken, the upper layer’s colors are checked for their lightness. Only if they are Lighter than the underlying color on the lower layer, will they be visible.
Similar to Overlay.
Checks which is darker the lower layer’s pixel or the upper layer’s double so bright. Then checks which is brighter of that result or the inversion of the doubled lower layer.
Perceptually the opposite of Multiply.
Mathematically, Screen takes both layers, inverts them, then multiplies them, and finally inverts them again.
This results in light tones being more opaque and dark tones transparent.
Soft Light (Photoshop) & Soft Light SVG¶
These are less harsh versions of Hard Light, not resulting in full black or full white.
The SVG version is slightly different to the Photoshop version in that it uses a slightly different bit of formula when the lightness of the lower pixel is lower than 25%, this prevents the strength of the brightness increase.
Similar to Overlay.
Mixes both Color Dodge and Burn blending modes. If the color of the upper layer is darker than 50%, the blending mode will be Burn, if not the blending mode will be Color Dodge.
This algorithm doesn’t use color dodge and burn, we don’t know WHAT it does do but for Color Dodge and Burn you need to use Hard Mix
