Certainly!
In the "Levels" menu, click on the far-right hand dropper (set white point) and click on the background. This makes everything of that brightness or brighter completely white.
Also in the "levels" menu, click on the "black point" dropper and click on a darker shadow on the lens. This makes everything that dark or darer turn black. It also re-defines the curves, so the tones blend.
Then, I added some contrast, darkened the highlights, and applied a little bit of Unsharpen mask (93%, .9 pixels, 1 threshold).
And that's about it!
