Ask any Dune fan whether there’s been a perfect adaptation of Frank Herbert’s seminal sci-fi novel, and you’ll get many different answers. Some might say Denis Villeneuve’s Dune movies are the closest to a Platonic ideal. The nerds might say it’s the Sci Fi Channel’s three-part miniseries, Frank Herbert’s Dune. Bigger nerds will say perfection exists only in Alejandro Jodorowsky’s deranged imagination, while the biggest nerds will argue that there’s no way to accurately adapt Dune at all. Only the real freaks, however, will speak up for David Lynch’s notorious 1984 flop.

Lynch’s Dune holds a fascinating place in pop culture history, releasing to such poor reviews and abysmal box office returns that the director famously disowned the film. It’s attained a kind of cult following in the decades since, with some fans proclaiming it to be a misunderstood masterpiece. But even star Kyle MacLachlan, who played the tragic hero Paul Atreides, acknowledges that Lynch’s Dune had an “impossible” task it couldn’t quite pull off.

If you’ve never seen a total solar eclipse, University of Colorado Boulder astronomer Doug Duncan has some advice about photographing the big moment: Don’t.

That’s surprising advice coming from the developer of the SolarSnap app, a camera app designed specifically for taking pictures of solar eclipses. But he says if you’ve never seen a total eclipse before, you’ll want to be in the moment.

“A photo of totality is neat, but it's like a photo of the Grand Canyon: If you've ever seen the Grand Canyon, it's so much more than a picture of it,” Duncan tells Inverse.

During several recent total eclipses, Duncan noticed people juggling their smartphones, their eclipse glasses, and their camera apps.

“It's kind of hard to hold your phone, hold a pair of eclipse glasses in front of your phone, and with your third hand, control the camera,” says Duncan. But if you are keen on taking a photo during the eclipse, he recommends sticking to the period of partial eclipse. Here’s how to take the best shot possible.
