I have a b/w image, slightly textured, meaning some pixels are not straight white or black but in the middle. I want to use it against dark background keeping just the light pixels. Have tried playing with Layer Style Blend Options, but it removed too much. Applying the Linear Dodge (Add) to a layer fixed my problem on screen. However, I now need to apply this effect to pixels and save as Transparent PNG. Is there a way of doing that, similar to how you can apply a layer mask? Saving transparent PNG creates problems since the main layer needs to have something in the background for Linear Dodge (Add) to work as intended.

Basically what I'm trying to do is discard everything that's not white and save as PNG
