Here are just a few of his other tips, via the NASA story:
Try including people in your shot
"There are lots of great photos of people appearing to be holding the moon in their hand and that kind of thing," he said. "You can get really creative with it."
Don't worry if all you have is a smartphone camera
"It’s all relative," he said. "For me, it would be maddening and frustrating -- yet it may be a good challenge, actually. You’re not going to get a giant moon in your shot, but you can do something more panoramic, including some foreground that’s interesting. Think about being in an urban area where it’s a little bit brighter."
Additionally, he recommends adjusting for the right light balance with your phone's camera settings, saying. "Tap the screen and hold your finger on the object (in this case, the moon) to lock the focus. Then slide your finger up or down to darken or lighten the exposure."
