My Go to Blend Modes ​

​

Multiply - Darkens an image

Screen - Lightens an image

Overlay - Boosts contrast

Color - Blends only the color

Luminosity - Blends only the brightness

​

The Darken blend modes
As we can see, the Darken, Multiply, Color Burn, Linear Burn and Darker Color blend modes make up the Darken group.

​

The Lighten blend modes
Next, the Lighten, Screen, Color Dodge, Linear Dodge (Add) and Lighter Color blend modes make up the Lighten group. Each of these blend modes lightens the image. 

​

The Contrast blend modes
Below that, the Overlay, Soft Light, Hard Light, Vivid Light, Linear Light, Pin Light, and Hard Mix modes make up the Contrast group. Each of these blend modes both darkens and lightens the image, which increases contrast. 

​

The Comparative blend modes
The Comparative group, made up of the Difference, Exclusion, Subtract and Divide blend modes. These blend modes compare pixels between layers, and none are used very often, especially in day-to-day tasks. However, they can result in some pretty interesting effects.

​

The Composite blend modes
Last but certainly not least, we have the Composite group, also known as the HSL group. HSL stands for "Hue, Saturation and Luminosity", which happen to be the names of three of the four blend modes included in this group, along with the Color mode. The blend modes in this group all have something to do with blending the color or luminosity (lightness) of a layer.
