Find out how to {Photograph} and Composite a Lunar Eclipse ⋆ Bryan Hansel Images

A lunar eclipse is a type of occasions that will get overhyped by the media and underestimated by photographers. Everyone needs a shot of the blood moon, however most individuals simply level a telephoto at it and name it achieved. I wished one thing extra — not simply the eclipse itself, however the full arc of the moon’s journey via the night time, set towards a recognizable foreground. Here’s how I deliberate and constructed that picture.

The Planning

The picture I had in thoughts required figuring out precisely the place the moon was going to be at each stage of the eclipse: earlier than, throughout, and after totality. I used The PhotoPills to calculate the moon’s place and observe its path via the sky over Grand Marais. Once I knew the arc, I might discover a spot on the town the place that path would line up with one thing attention-grabbing within the foreground. I settled on a place that put the lighthouse within the body.

Focal size issues greater than folks assume for this type of shot. I knew I wished to make use of 50mm, which is huge sufficient to indicate the total arc of the moon throughout the sky, however lengthy sufficient that if I printed it massive the moon would have actual element in it quite than simply being a brilliant dot. Getting the focal size proper earlier than you exit saves quite a lot of frustration on location.

The Shooting

I ran two cameras that night time. The first was arrange for the huge panoramic shot with the lighthouse and harbor. The second was zoomed in tight on the moon to seize element in the course of the eclipse itself.

The huge shot is a panoramic composite constructed from three separate frames shot at completely different factors alongside a digicam pan: left aspect with the lighthouse, center with the western marker, and proper aspect protecting the marina. Each body overlapped the subsequent by about 20 to 25%, which gave me sufficient shared element to sew them collectively in Photoshop.

Here’s the half that took probably the most coordination: every particular person moon within the remaining picture comes from a separate shot taken in the course of the corresponding panoramic place. So whereas I used to be capturing the left third of the panorama, I additionally captured the moons that belonged in that part of the sky. Then I rotated to the center place and captured the subsequent group of moons. Then the precise place for the final group. You must assume via the timing rigorously earlier than you begin. Once the eclipse is transferring, you don’t get a second likelihood.

At daybreak, after the eclipse was over, I reshot all three panoramic positions with the brighter morning mild to get cleaner base pictures for the background.

The Compositing

Back on the laptop, I sewed the daybreak panoramic frames into one massive base picture. Then I went via every particular person moon shot and positioned it the place it belonged within the arc — lining every one up with its appropriate place within the sky relative to the foreground.

I obtained fortunate in a single respect: the lighthouse was seen in a number of the moon pictures, which gave me reference factors to work from. Without that, the alignment would have been largely guesswork.

The principal downside I bumped into was parallax. When you pan a digicam for a panoramic shot and not using a specialised nodal level tripod head, the attitude shifts barely between frames — objects at completely different distances don’t line up completely while you sew. Because of that, the moons didn’t fall right into a clear, mathematically exact arc the way in which I’d hoped. In the top I drew a curve via the moons and nudged a couple of of them onto it. Whether it’s a correct arc or not, I can’t say, however it seems to be proper, and the ultimate picture captures the sensation of the night time higher than a technically excellent model in all probability would have.

What I’d Do Differently

A nodal level panoramic head would have solved the parallax downside and made the compositing a lot cleaner. If you’re planning a shot like this, it’s well worth the funding.

I’d additionally plan the moon timing much more rigorously. Knowing precisely which moon phases I wanted to seize throughout every panoramic place, and having that written down earlier than I began capturing would have made the night time go extra easily.

One Last Thing

Lunar eclipses are predictable years prematurely. NASA publishes eclipse schedules far into the longer term, so there’s no excuse to not plan. Find the subsequent one, spend an hour in PhotoPills determining the place the moon will observe over a foreground you care about, and go make one thing extra attention-grabbing than a telephoto closeup of a pink moon.
