I watched a youtube video on Photoshop Blend-If tutorial.
From what I learned from tutorial is that you can select a low value (which can break into 2 points for soft transitions)
and a high value (which can also break into 2 points for soft transitions)
So I have allowed 4 points in total (Low Minimum & Low Maximum for 2 point soft transition for low point and
High Minimum & High Maximum for point soft transition for high point).
The plug-in is called Mask-If.
- Select the layer you'd like apply mask-if to
- Run Plug-in, select channel, select 4-point numbers from 0-255 (that you'd like to use like in Photoshop Blend-If)
- Click OK
- Plug-in will create a layer called/named "Mask-if" for you to play with afterwards (but it'll be set to not visible because it will already apply that mask to your selected layer).
