I have a grey scale image with different shades of grey (it's not this image, but it's the general idea, this is from Wikipedia as an example).
I want to use this as a texture in a game engine eg unity, unreal, etc.
And I want a pure black and white version that can be used as bump/displacement map.
So I want the head and the Liberty (and other text) text to be pure white on a black background. I selected the head with the magnetic lasso tool and put that into a different layer and used the bucket paint tool with white to fill the head in (there is probably a better way to do this but wasn't sure).
But i'm struggling with the liberty text. I have selected that and it is also in a separate layer, but can't use the bucket tool to make each letter white obviously. I tried changing the levels but it remains grey.
Was after some advice.
