This is an auto action that I set up to usually use it in my projects
Not something really fancy, but I use it to prepare all the layers when I start a new project.


It's an auto action that create all the initial layers that I might use in the project. Most of them are pretty straight forward.
__________
Except 2 of them that might be used (maybe) which is
1. "Contrast Check" layer
- It's a layer filled with 50% brightness + 0 Saturation set to "Color" blending mode.
- Color Blending mode : keep the brightness of the layer below and apply the Hue/Sat of the "color mode" layer (in this case is grey).
- Used for checking the overall contrast of the image to see if something is off in term of Brightness.

__________
2. "Temperature / Saturation Check" layer
- It's the opposite of the "Contrast Check" layer
- Also filled with 50% brightness + 0 Saturation set to "Brightness" blending mode
- Brightness Blending mode : keep the Hue/Saturation of the layer below and apply the Brightness of the "brightness mode" layer (in this case is grey).
- Used for checking the overall Saturation/Temperature of the image to see if something is off in term of Saturation/Temperature..

Those 2 layers are useful in it's own way. You might not need them but it's there.
It can also help when you have 2 pieces of image that come from a different place (like when you're using Green Screen with a different background).
Those 2 layers will guide your adjustment to blend images together instead of using you own eyes to guess.
