Levels - Quick Question

[cjwidd]

When applying a bitmap mask to a fill layer - in this case, a greyscale image - why does simply adding a levels modifier make such a dramatic difference to the appearance of that mask?

I don't see any difference on my side after simply applying a levels filter. Do you have screenshots?

Jeremie, I apologize, I thought I deleted this question. It was a simple mistake on my part - the channel was inverted and I did not realize. Feel free to remove this post.
