I don’t know if anyone remembers this thread:how to apply the 'vivid light' blending mode like in photoshop
I remembered it today, and then I found a detailed article (in Chinese) from April, and finally got a rough idea of how it works, and performed some simulations
Lowering the filling means lowering the opacity of the B layer, mixing with the neutral layer first, and then doing the blending of color darkening and color lightening
In ps, there are a total of 27 blending modes, of which 8 blending modes have different algorithmic compensations when the opacity and filling degree are the same. Assuming a full score of 100 points, the difference between opacity and filling is sometimes the difference between 95 points and 100 points, and sometimes the difference between 70 points and 90 points.
Except for those 8 modes, there is no difference in adjusting opacity and filling degree in other modes.
The 8 special mixing modes are:
Burn, Linear Burn,-mixed white
Color Dodge, Linear Dodge, Difference-mixed black
Vivid Light, Linear Light,-mixed gray
Hard Mix-under study
ps: fill 20/vivid light
krita: The upper layer opacity 20/normal; and the middle gray are placed in a layer group, and the group is set to vivid light (must be grouped)
