Filters.

Well - I took one photo looking through the steel gate to the backstairs at Live Arts. And I took another photo through a red plastic flyswatter in my kitchen. I mashed them together with Pixlr. And then I fartnarkled a bit more - also with Pixlr.

If I'd been less lazy, and more inspired, I might have invented an interesting homemade filter. But there we are. Or here we are.
