Is there a way to increase brightness beyond the default setting on MacBooks?

Just got the new MacBook Pro Retina, and I love it except for the fact that the overall brightness was decreased by 20-25%. A couple reviews talk about this noticeable reduction in brightness (http://www.extremetech.com/computing/130819-analyzing-the-macbook-pro-with-retin a-display), and I assume it has to do with the power consumption of the retina display.

That said, I've always thought the highest brightness in previous generation MacBooks was barely bright enough as it was, and now with this reduction in default brightness, I'm finding it hard to use. I know I may be in the minority thinking this, but I may have to return the machine if I can't find a workaround.

Is it possible to increase brightness beyond the default setting? Is there a command line setting that I can adjust? I'm well-aware of the battery trade-off this will have, but I don't care. I have to be able to see the screen.

Any thoughts and/or suggestions are appreciated.
