It happens every single time. You look up, and the moon is this haunting, deep crimson color—the kind of thing that makes you want to drop everything and grab your phone. You snap a quick picture, expecting to capture that eerie, cosmic magic. Then you look at your screen. Honestly, it’s depressing. Instead of a majestic lunar eclipse, you’ve got a blurry, overexposed white dot that looks like a streetlamp in a fog. It’s frustrating.
Capturing decent photos of blood moon isn't just about having a thousand-dollar lens, though that certainly helps if you’ve got the budget. It’s actually more about understanding why your camera is lying to you. Your phone or DSLR sees that bright circle in a pitch-black sky and panics. It tries to brighten the whole image because it thinks it’s "dark out," which completely blows out the delicate red details of the eclipse. If you want to stop taking bad photos and start capturing what your eyes actually see, we need to talk about what’s actually happening during a Total Lunar Eclipse and how to trick your gear into cooperating.
Why the Moon Turns Red (and Why Your Camera Hates It)
A blood moon isn't some supernatural omen, obviously. It’s Rayleigh scattering. It’s the same reason sunsets are red. When the Earth slides directly between the Sun and the Moon, it blocks the direct light. However, Earth’s atmosphere acts like a lens. It bends the sunlight around the edges of our planet. The blue and violet light gets scattered away—gone—while the longer wavelengths, the reds and oranges, pass through and hit the lunar surface.
Basically, when you’re looking at a blood moon, you’re looking at the projection of every single sunrise and sunset on Earth happening all at once. Pretty cool, right?
But here’s the problem for your camera: the light levels drop off a cliff. During the totality phase, the moon is significantly dimmer than a full moon. You can’t use the "Looney 11" rule here. You’re dealing with a moving target in low light. If your shutter speed is too slow, the moon blurs because the Earth is rotating. If your ISO is too high, the photo looks like it was taken through a screen door covered in sand. It’s a delicate balance that most "Auto" modes just can't handle.
The Gear You Actually Need (and the Stuff You Don’t)
You don’t need a telescope. Seriously. While a telescope is great for seeing craters, a decent telephoto lens on a tripod will get you a stunning shot. If you’re using a smartphone, you’re going to be fighting an uphill battle, but it’s not impossible.

The absolute "must-have" is a tripod. You cannot hold a camera steady enough for a 1-second or 2-second exposure. Period. Even the heartbeat in your thumb will cause camera shake. If you don't have a tripod, prop your phone against a rock or a fence post. Use a remote shutter or the self-timer function. Even the act of pressing the "capture" button on the screen creates enough vibration to ruin the sharpness of your photos of blood moon.
For those using a "real" camera—a mirrorless or DSLR—you want something with at least 200mm of focal length. 400mm is the sweet spot. At 600mm, you’re filling the frame. But remember, the longer the lens, the faster your shutter speed needs to be to avoid "motion blur" from the Earth’s rotation. NASA’s photographers often suggest keeping your shutter speed faster than 1/2 a second if you aren't using a star tracker.
Settings that actually work
Forget "Night Mode" on your iPhone or Samsung for a second. It often over-processes the image, making it look like a cartoon. Go into "Pro" or "Manual" mode.
- ISO: Start at 400 or 800. You need sensitivity, but don't go to 6400 unless you like digital noise.
- Aperture: Open it up. f/2.8 or f/4 is ideal. You want as much light as possible hitting that sensor.
- Shutter Speed: This is the tricky part. For the "blood" phase, try 1 or 2 seconds. If it's too dark, bump the ISO before you slow the shutter further.
- Focus: Set it to manual. "Infinity" focus isn't always perfect on modern lenses. Use your "Live View" screen, zoom in digitally on a star or the edge of the moon, and twist that focus ring until it’s tack-sharp.
Common Mistakes People Make Every Eclipse
One big mistake is waiting for "Totality" to start taking pictures. The "partial" phases, where the Earth's shadow (the umbra) slowly bites into the moon, are actually some of the most dramatic shots you can get. The contrast between the bright white lunar surface and the deep red shadow is incredible.
Also, don't forget the environment. A giant red moon floating in a sea of black is fine, but it lacks scale. Some of the best photos of blood moon include "foreground interest." Think of a jagged mountain range, a lighthouse, or even a city skyline. This requires planning. You need to know exactly where the moon will be in the sky. Apps like PhotoPills or The Photographer’s Ephemeris are lifesavers here. They use augmented reality to show you exactly where the moon will rise and set from your specific GPS coordinates.

Another thing? White balance. If your camera is set to "Auto White Balance," it might try to "correct" the red color because it thinks the lighting is "wrong." Set your white balance to "Daylight" (approx 5500K). This ensures the camera records the colors exactly as they are, preserving that deep, brick-red hue.
The Post-Processing Secret
Almost every professional moon photo you see has been edited. Not "faked," but refined. When you shoot in RAW format—which you absolutely should—the image will look a bit flat and gray straight out of the camera. That’s normal.
In a program like Lightroom or even a mobile editor like Snapseed, you’ll want to nudge the "Contrast" up and pull the "Blacks" down. This makes the moon pop against the sky. Be careful with the "Saturation" slider. If you overdo it, the red looks neon and fake. Instead, try adjusting the "Vibrance" or specifically targeting the "Reds" in the HSL (Hue, Saturation, Luminance) panel.
One "pro" move is to take two exposures. One for the moon itself (to get the red detail) and one longer exposure to capture the surrounding stars. Then, you blend them. It’s a bit more advanced, but it’s how you get those "National Geographic" style shots where the moon is red and the Milky Way is visible behind it. In reality, the moon is usually too bright to see many stars near it in a single shot.
Dealing with Clouds and Bad Luck
Nature is indifferent to your photography goals. Sometimes, you plan for months, and a cold front rolls in 10 minutes before totality. It happens. If it’s patchy clouds, don’t give up. "Cloud-mossed" photos of blood moon can actually look more cinematic and spooky than a clear sky. The clouds can act as a natural filter, adding texture to the frame.

If it’s a total washout? Honestly, just put the camera away. Sometimes we get so caught up in the settings and the gear that we forget to actually look at the thing. A blood moon is a rare celestial alignment. If the tech isn't working, just lean back and watch the shadow move. There’s always another eclipse, but you’ll never have this specific moment back.
Practical Steps for Your Next Shoot
To get the best results, start preparing two days before the eclipse. Check your battery levels—cold night air drains them twice as fast as usual. Bring a spare. Clear your memory cards. You’ll be surprised how many photos you’ll take when you start "bracketing" your exposures (taking one shot bright, one medium, one dark).
- Location Scouting: Use an app to find a spot with a clear view of the horizon. Avoid areas with heavy light pollution if you want stars in your shot.
- Test Your Focus: Practice on a regular full moon a month before. If you can’t get a sharp photo of a white moon, you won't get a sharp one of a red moon.
- Stability is Key: If it's windy, hang your camera bag from the center column of your tripod to weigh it down.
- Shoot RAW: It gives you the "data" you need to fix mistakes in lighting later.
- Check the Weather: Use an astronomical weather app like Clear Outside which tracks "transparency" and "seeing" conditions, not just "is it raining?"
Once you have your shots, don't just dump them on Instagram immediately. Look at them on a larger screen. Check the sharpness. Pick the best one, do a subtle edit to bring out the shadows, and you'll have a piece of astronomical art that actually looks like the real thing. Proper planning beats expensive gear every single time.
Go out there, stay warm, and keep your shutter speed up. The moon moves faster than you think.
