Photographing the Lunar Eclipse TIPS & TRICKS
Rent your super telephoto lenses now so that they arrive in time for you to shoot the lunar eclipse, which is happening next week, April 14th and 15th, 2014. This is the first visible total lunar eclipse since December 10th, 2011. The first hints of action begin at approximately 12:30AM EDT with the real action not starting until about 3AM EDT (better details below) – prepare coffee.

For those who don’t know, a lunar eclipse occurs when the sun, Earth, and moon line up so that the Earth’s shadow falls on the moon, darkening it and producing a “rusty” color which is why some people call this a “Blood Moon”. This is caused, for those light nerds out there, by refraction of sunlight by the Earth’s atmosphere.
It’s pretty cool stuff and you won’t want to miss capturing it. Here to give us some tips on how to that is Michael Frye, a professional photographer who specializes in landscapes and nature with plenty of experience shooting the lunar eclipse.

Michael’s photographs and articles about photographic art and technique have appeared in publications around the world, and he is the author and/or principal photographer of four books: The Photographer’s Guide to Yosemite, Yosemite Meditations, Yosemite Meditations for Women, and Digital Landscape Photography: In the Footsteps of Ansel Adams and the Great Masters. Michael has also written three eBooks: Light & Land: Landscapes in the Digital Darkroom, Exposure for Outdoor Photography, and Landscapes in Lightroom 5: The Essential Step-by-Step Guide.

Photographing the Lunar Eclipse
by Michael Frye

On the night of April 14th and 15th, viewers in North America will be able to see a total lunar eclipse. Most people should be able to see the whole eclipse sequence, though viewers in the far northeast will miss the very end of the event. This NASA page shows where the eclipse will be visible throughout the world.
I’ve photographed several lunar eclipses and they’re spectacular events to view and photograph. But photographing at night presents challenges. How do you focus in the dark? How do you get the right exposure? To help speed your learning curve, here are my best tips for making your own lunar eclipse photographs:
Equipment

• DSLR or mirrorless camera with full manual exposure control. Test your mirrorless camera first to make sure you can focus and compose in the dark with the electronic viewfinder (see Focusing below).
• At least two fully charged camera batteries.
• Sturdy tripod.
• Cable release, electronic release, or remote.
• Interval timer or watch.
• Flashlight or headlamp.

Moon Position
Finding a good location means first moving away from cities to avoid light pollution. If you live on the east coast, you’ll need a clear view to the southwest while west coast viewers will be looking almost directly south.
To calculate the moon’s position accurately – if you want to line it up with a building or mountain, for example – there are several excellent apps available. The Photographer’s Ephemeris ($8.99 for iOS or Android, free for the desktop) is one of the best. PhotoPills ($9.99, iPhone only) has similar tools, plus an Augmented Reality feature for visualizing the path of the moon against a live picture of the scene in front of you.

Of course, timing is important too, so here are the important moments:
Partial eclipse begins: 1:58AM EDT April 15th / 10:58PM PDT April 14th
Total eclipse begins: 3:06AM EDT / 12:06AM PDT April 15th
Greatest eclipse: 3:45AM EDT / 12:45AM PDT April 15th
Total eclipse ends: 4:24AM EDT / 1:24AM PDT April 15th
Partial eclipse ends: 5:33AM EDT / 2:33AM PDT April 15th

When the partial eclipse begins the moon will become a smaller and smaller crescent as the Earth’s shadow seems to take a bite out of the moon. During the total eclipse, the moon will look much dimmer and turn orange or even red-orange in color. Just after the total eclipse the moon will return to a slender crescent and then get larger and larger until the eclipse ends and the moon becomes completely full again.

Focusing
Since most modern lenses focus past infinity, you can’t just crank the focusing ring all the way to the end and expect to get sharp photographs. The most accurate way to focus in the dark, by far, is to use live view, zoom in on the moon, and focus manually. It may help to crank up the ISO for this. Autofocusing on the moon should also work if the moon is bright enough (like before the total eclipse begins) – but be sure to then turn autofocus off so that the camera doesn’t accidentally focus on something else.

Exposure
Light meters are useless for getting good exposures of the moon because even a one-degree spot meter can’t read just the moon but will also include some of the surrounding black sky. So here are some suggestions based on past experience, including making the photographs you see in this post. You’ll need to use manual exposure mode and check your camera’s highlight alert (the “blinkies”) to make sure you’re not overexposing the moon:

Full moon, or moon more than half visible: 1/60 sec. at f/11, 200 ISO
Half to one-quarter of the moon visible: 1/30 sec. at f/11, 200 ISO
Less than one-quarter of the moon visible: 1/15 sec. at f/11, 200 ISO
Just the edge of the moon lit: 1 sec. at f/11, 200 ISO
Fully eclipsed at the beginning and end of totality: 8 sec. at f/11, 800 ISO
Fully eclipsed, deepest totality: 8 sec. at f/11, 1600 ISO

In the examples you see in this post, I’ve kept the aperture constant at f/11, but if you need more depth-of-field you could use f/16 and either double the ISO or the length of the exposure. You want to keep the exposures relatively short, otherwise the moon will move and blur. You can get away with eight or maybe even fifteen seconds with a wide-angle lens, but with a telephoto lens you need to use shutter speeds of four seconds or less. To find the maximum exposure time for your lens before movement appears, divide the focal length into 400. So 400 ÷ 25mm = 16 seconds, or 400 ÷ 100mm = 4 seconds. Bracketing exposures is a good idea.

Eclipse Strategies
Trying to include a foreground makes things more complicated, so the simplest way to photograph a lunar eclipse is to take a long lens and zoom in on the moon. If you photograph the eclipse from beginning to end you can even use Photoshop to assemble your images into a montage showing the whole sequence.
A more evocative approach – but a more complicated one – is to capture the eclipse sequence with a foreground, as I did in the photographs in this post. To do this you’ll first need to figure out the exact path the moon will take so you can compose your photograph accordingly. The apps I mentioned above, PhotoPills and The Photographer’s Ephemeris, are invaluable for this.

Once you’ve composed, make sure your tripod is solidly planted and locked tightly. You’ll want to focus on the foreground, not the moon, and use a small enough aperture to get both foreground and moon in focus. A bright flashlight and live view are helpful for focusing on the foreground.

Then make a series of exposures to capture the eclipse sequence. In the two photographs included in this post, the interval was ten minutes between each moon capture, but you could make it fifteen or twenty minutes if you want to space the moons farther apart. Just make sure you keep the interval the same throughout the sequence. You can use an interval timer for this or just use a watch and trip the shutter manually (using a remote or cable release, of course). You’ll need to adjust the exposure times (and possibly the aperture or ISO as well) as the moon dims and brightens.

In my photographs I used electronic flash or a flashlight to light-paint the trees in between making exposures of the moon. Light painting is a complex subject that I won’t get into here and, if this is the first time you’ve ever tried photographing an eclipse, I’d suggest you keep it simple and don’t try light painting. Just try to capture single images of the moon itself, or perhaps a sequence with silhouetted trees or other objects in the foreground.

If you get ambitious and try a sequence, the final step is to assemble the images in Photoshop. From Lightroom you can select the images and choose Photo > Edit In > Open as Layers in Photoshop, and Photoshop will stack the images into one document as separate layers. Or you can do this by hand using the Move tool to drag one image on top of another; just make sure you hold down the shift key while dragging so that the images align properly.

Then change the blending mode of every layer except the bottom one to Lighten. This makes light areas override dark areas, so the moon from one frame will override dark sky from another frame. As you do this you’ll see all the moons magically appear and complete your sequence. If you light-painted a tree or other object, that too will appear when you change the blending mode for that layer. If you used a telephoto lens to capture the whole eclipse sequence, you can use the Move tool to drag each layer around and arrange the moons on your canvas.
Photographing a lunar eclipse takes planning and a willingness to lose some sleep but it can be a tremendously rewarding experience. And if your photographs don’t turn out as well as you hoped, you’ll get another chance because there will be two total lunar eclipses visible in North America in 2015.

Therein lies my problem.  I would love to try and photograph the event but there is no way in Hell I could stay up for that and try to function later that day.  :(
Take your camera with you dammit. You can't take your next "best photo" if your camera is sitting at home in the bag, now can you?

Well looks like cloud cover and rain will keep me from photographing this event.  It might be cleared off by the end of the event, but I am afraid i am a "fair weather" nighttime photographer in that I will be asleep and will not want to get up at 3 for a slight chance to see the end of the event.

I hear ya here Brother!  But...I am actually going to set my phone to wake me at 2 and I'll get up to see if the clouds are still around (it actually SNOWED here today...). As of right now (7pm) it is still 100% cloudy but the weather folks have said it should clear out by midnight...we'll see.

I almost mentioned snow as there is a chance later tonight as it moves down from your neck of the state.  You might get to see some of it if it clears by midnight.  It should start just before midnight for us in the Central Time Zone

Well, it's not 10PM and every single cloud has left.  I can't say how it will be in a few hours but as of now...I am staying up and getting ready to shoot the moon (so to speak).  It's also only 32 degrees and dropping so this won't be the most fun I've had.  I just hope I can get a decent shot now.

You lucky man.  I love the temp too.  Is it windy?  My daughter in Texas said it was clear but windy.  She is going to try to get some full moon shots when it is red, then head for bed.

Weather is on in a bit and will check the radar then.  Not looking to hopeful for me.

Right now (10:30PM) the wind is going WNW at 7 mph so it's not too bad. I have my tripod set up on the south side of my house to help block the wind. If it doesn't pick up any more...I might be alright.
Just went out for a couple of test shots...DAMN it's cold.
