You’ve seen them. Those viral photos of a blood moon that look like a scene from a high-budget sci-fi flick, where a massive, rust-colored orb hangs impossibly large over a city skyline. Then you step outside during a total lunar eclipse, hold up your iPhone, and snap a grainy, blurry white dot that looks more like a dirty LED bulb than a celestial event. It's frustrating. Honestly, it’s enough to make you want to put the phone back in your pocket and just go inside to watch Netflix.
But there’s a reason for that gap between reality and your camera roll.
A blood moon occurs during a total lunar eclipse when the Earth slides directly between the sun and the moon. Instead of going completely dark, the moon gets bathed in a deep, moody red. This happens because Earth’s atmosphere scatters the blue light and lets the red wavelengths pass through—essentially projecting every sunset and sunrise on Earth onto the lunar surface all at once. It’s a phenomenon Rayleigh scattering explains, the same reason the sky is blue and sunsets are orange.
Getting a good shot of this isn't just about having an expensive camera. It's about understanding how light behaves when it's being filtered through thousands of miles of dust and clouds.
The Gear Reality Check
Most people think they need a $5,000 rig to get decent photos of a blood moon, but that’s not entirely true. You do, however, need to accept that a standard smartphone lens is basically a wide-angle eye. It’s meant for selfies and brunch, not for a rock 238,000 miles away.
If you’re using a DSLR or mirrorless camera, focal length is your best friend. A 50mm lens makes the moon look like a speck. A 200mm lens starts to show some detail. If you really want to fill the frame, you're looking at 400mm or even 600mm. That's big glass. But even if you don't have a telephoto lens the size of a bazooka, you can still make it work by focusing on the "lunar landscape" approach. This means including a foreground—like a lighthouse, a jagged mountain range, or even a local water tower—to give the moon scale and context.
Tripods are non-negotiable. Period.

During the totality phase of the eclipse, the moon is significantly dimmer than a full moon. You’re going to be using longer shutter speeds. If you try to hand-hold your camera, the tiny vibrations from your heartbeat will turn that blood moon into a red smear. Even the act of pressing the shutter button can cause enough "camera shake" to ruin the sharpness. Use a remote shutter release or the built-in 2-second timer on your camera. It makes a world of difference.
Exposure is the Great Lie
Here is where most hobbyists get tripped up. When you look at the moon, it looks bright. But when it’s a blood moon, it’s surprisingly dark. Your camera’s "Auto" mode is going to freak out. It sees a giant black sky and thinks, "Wow, it's dark out here! I better brighten everything up!"
The result? A blown-out, overexposed white circle with zero red detail.
To get those iconic photos of a blood moon, you have to go full manual. You want to keep your ISO relatively low to avoid "noise" or graininess, but you can't keep it at 100 because the shutter would have to stay open for too long, causing the moon to blur. Wait, why would it blur on a tripod? Because the Earth is spinning and the moon is orbiting. If your shutter is open for more than a couple of seconds, the moon actually moves across the frame.
Try starting with these settings during totality:
- Aperture: $f/8$ or $f/11$ for maximum sharpness.
- ISO: 400 to 800 (go higher if your camera handles low light well).
- Shutter Speed: 1 to 2 seconds.
Adjust from there. If it's too dark, bump the ISO before you lengthen the shutter speed. You’ve gotta find that "Goldilocks" zone where the red is saturated but the craters are still crisp.

The Smartphone Struggle
Can you take photos of a blood moon with a phone? Sorta.
Modern flagship phones like the Samsung Galaxy S23/S24 Ultra or the iPhone 15/16 Pro have "Night Mode" and impressive digital zoom. Samsung’s "Space Zoom" actually uses AI processing to recognize the moon and sharpen the texture. Some people call this "cheating" because the phone is essentially overlaying a high-res texture of the moon onto your blurry photo. Whether you care about that is a personal choice, but the results look good on Instagram.
For iPhone users, the key is to lock the focus and exposure. Tap the moon on your screen, then slide the little sun icon down until the moon actually looks red and the details emerge. Don't just pinch-to-zoom to the max; digital zoom just crops the image and loses quality. Zoom in a little, then crop the photo later in an editing app like Lightroom or Snapseed.
Composition and the "Moon Illusion"
Ever notice how the moon looks massive when it’s near the horizon but tiny when it's high in the sky? That’s the Moon Illusion. It’s a trick of the brain. To recreate that feeling in your photos of a blood moon, you need distance.
If you stand right next to a tree, the moon will look small. If you stand half a mile away from that same tree and use a long zoom lens, the tree and the moon will appear to be a similar size. This is called lens compression. It's how professional photographers get those shots where the moon looks like it's about to crush a city skyline.
Plan your shoot using apps like PhotoPills or The Photographer’s Ephemeris. These tools tell you exactly where the moon will rise and set, down to the degree. You can literally scout a spot days in advance, knowing that at 11:42 PM, the blood moon will be perfectly framed between two specific skyscrapers. It takes the guesswork out of the equation.

Weather and Atmosphere: The Uncontrollable Variables
Sometimes you do everything right and the photos still suck. Atmosphere is a fickle beast. If there’s a lot of humidity or "heat shimmer" (atmospheric turbulence), the moon will look like it's underwater. Cold, crisp, dry winter nights usually offer the best clarity.
Volcanic ash or wildfire smoke can actually make a blood moon look even deeper red, which is a weird silver lining to environmental issues. During the 1992 eclipse after the eruption of Mount Pinatubo, the moon was so dark it almost disappeared because of the dust in the stratosphere. Every eclipse is different. Some are bright orange, others are a dark, bruised purple. That’s the beauty of it.
Post-Processing Without Overdoing It
When you get your photos of a blood moon onto a computer, you'll probably notice they look a bit flat. That's normal. RAW files (if your camera/phone supports them) hold a ton of data that isn't visible at first glance.
Don't just crank the saturation to 100. That’s how you get "nuclear" looking moons that look fake. Instead:
- Boost the "Clarity" or "Texture" slightly to bring out the craters.
- Adjust the "Whites" and "Blacks" to create contrast.
- Use a slight "Dehaze" if the sky was a bit misty.
- Fix the White Balance. Sometimes cameras get confused and try to "correct" the red out of the moon. Switch the preset to "Daylight" to keep the colors true to what you saw with your eyes.
Real-World Insight: The 2025/2026 Eclipses
We’re heading into a cycle of some pretty spectacular lunar events. If you missed the last one, don't sweat it. The key is to practice on a regular full moon. The settings will be different (a regular full moon is much, much brighter), but the mechanics of focusing and steadying your tripod are the same.
Total lunar eclipses are slow. Unlike a solar eclipse, which lasts minutes, a blood moon can hang there for over an hour. You have time to breathe, change your settings, and try different compositions. Don't spend the whole time behind the lens. Take a second to just look at it. There's something deeply humbling about seeing the Earth's shadow creeping across another world.
Actionable Steps for Your Next Shoot:
- Check the Date: Look up the next total lunar eclipse for your specific longitude. Partial eclipses are cool, but they don't give you that deep red "blood" effect.
- Scout the Spot: Use an app to find a foreground element (building, tree, mountain) that faces the direction of the moon's path.
- Charge Everything: Cold night air kills batteries. Bring a spare.
- Manual Mode: Switch to 'M'. Turn off your flash (it won't reach the moon, I promise). Set your focus to infinity.
- Ditch the JPEG: If your device allows, shoot in RAW format. It gives you the "room" to fix exposure mistakes later.
- Steady Up: Use a tripod or a beanbag. Even propping your phone against a rock is better than holding it.
Capturing great photos of a blood moon is essentially a lesson in patience and technical stubbornness. You're fighting low light, distance, and the literal rotation of the planet. But when you finally see that red, textured sphere pop up on your screen—sharp and haunting—it's a massive rush. Stick to the manual settings, find a good foreground, and stop trusting your phone's "Auto" mode to do the heavy lifting for you.
