If you take a flash picture at night with an entirely empty background, the foreground object will seem to be floating in inky blackness. In this picture, a bearded iris is in the foreground but all the background stuff is so far off that the flash doesn’t reach it.

I would have tried a few other things to see if I could get a better example, but it was cold and I got bored quickly. Maybe some other time. What would be a good object to study?

The truth needs defenders. Be one.

Tomorrow is the last day of our Spring Membership Drive, and we need to raise 1,000 new donations to fund the critical investigations our team is hard at work on. As of today, we’re still less than halfway there—and we can’t afford to fail!

Our nonprofit newsroom is funded by donors from every state in the union—blue, red, and purple, all part of a community of readers who care about the future of our democracy.

We’re independent from corporations and uninfluenced by those in power. Our commitment is solely to the truth. That’s only possible because of readers like you, who believe in the importance of independent, fearless journalism.

Be the reason these stories get told. Make a donation today.
