Linear work flow and Photoshop

Hey guys!

I’m having a bit of a blonde moment… I’m trying to paint textures in Photoshop for a scene that uses LWF so I want to paint the textures viewing them with a gamma adjustment of 0.4545. I was looking for an exposure adjustment layer so I could view the map with the corrected gamma but cant seem to find one, is there another way to do it that I’m missing?

There is no need to worry about that if you set your Gamma Bitmap Input setting to 2.2 in Max.
