Christmas Day's rare full moon: How to take a great picture
'You don’t need extra dark skies,' says CBC Starman Don Hladiuk
Dec. 25 brings with it something we haven't seen in almost four decades — a full moon on Christmas.

The precise moment of the full moon will be at 4:11 a.m. MT Friday in Calgary — but even by the time folks are getting up to see what's under the tree, there should still be a good show, according to CBC Calgary's go-to astronomer, Don Hladiuk.
"As the sun is rising in the east, look in the west and you'll see this beautiful full moon, provided the skies are clear, setting in the west," the starman said.
"It doesn't happen very often: it's surprisingly rare."
In fact, the last Christmas Day full moon happened in 1977 — the year the first Star Wars movie came out, Hladiuk says.
"And guess what came out in December of this year, another Star Wars movie, so it's almost like full circle in a way."
How to take a good picture of the moon
Hladiuk says snapping a good picture of the moon should be quite easy.
"The full moon is so bright, you can be in the most light-polluted part of Calgary [or in] the country, where you could read a newspaper to the full moon it's so bright," he said.
"So that's the beautiful part of a full moon. You don't really have to travel anywhere to see it. You don't need extra dark skies."
Hladiuk recommends an ISO of anywhere from 400 to 800 and a fairly fast shutter speed to be sure not to overexpose the picture.
"If you're just trying to take a picture of the moon itself, it is surprisingly bright and you'll need like 1/125th of a second," he said.
He says a long lens of 300 to 400 mm will allow you to zoom right in on the moon itself.
"But there's also another thing you can try, and that's just taking the scenery illuminated by the moonlight," he said.
A longer exposure of four to six seconds can create an interesting effect, he said.
"It'll look like daylight, but you'll still see stars in the background," he said.
Tips for using an iPhone
If you're shooting with an iPhone, the Manual app — $3.49 in the App Store — will allow you to turn your camera phone into an almost dSLR-quality tool, according to CBC photographer Evan Mitsui.
If you don't have the Manual app, try using the built-in focus lock feature to set the exposure on a bright, foreground light source — like a flashlight.
Then, when it's locked in, tilt your phone skyward and snap a shot of the moon, Mitsui says.
