How to create mask for transparent?

[Harvey Clayton]

I'm having two files. One is regular image and other is a black/white version of it. I want to use the white area as visible and black as invisible. Is there a was to do this? I attached files for your reference. Regular mask is doing it, white brush reveals the masked image and black hides it. But I don't know how use my image as a mask.

I imagine that the OP tried and failed to attach the files, rather than actually forgetting. As an anti-spam measure, new users cannot attach files to the first post: attachments should become enabled for subsequent posts.

One solution juste mine   open this file

I made a B&W  extract off the Color layer,

I select the sky with Threshold ajustment ( more faster in my case )

Merge B&W with This Threshold obtain a layer

Drag it on  duplicate Background layer (Original color version)

I  obtain a layer with a Kind of mask, this layer have  internal properties,  in this layer you can make any adjustment local

Protection against global adjustment as long as it remains in this layer or is not isolated by a Group
