How to Photograph Tonight's Blood Moon (And Actually Get a Shareable Photo)

The night of August 27-28, 2026 brought a deep partial lunar eclipse — 96.3% of the Moon's disk inside Earth's umbral shadow at peak, visible across the Americas and parts of Europe and Africa — and most people who tried to photograph it on a phone got a dim, overexposed white blob instead of the blood-red Moon they actually saw. That gap between what your eyes saw and what your camera captured comes down to one thing: eclipse photography needs two completely different exposure settings depending on the phase, and almost nobody adjusts mid-shoot. Here's the fix, plus what to do with the file once you've actually got the shot.

Why Your First Attempt Probably Came Out Wrong

A camera's auto-exposure is built to average a scene toward middle gray, and a bright Moon against a black sky confuses that logic badly — you either get a blown-out white circle with zero surface detail, or a correctly exposed Moon sitting in a sky so black the shot looks lifeless. Manual mode isn't optional for this one. And because the Moon's brightness drops dramatically as more of it moves into shadow, the settings that worked at the start of the eclipse will produce a nearly black frame by totality if you don't change them.

The Two Settings You Actually Need

During the bright partial phases, before much of the Moon is covered: ISO 100-400, aperture around f/8, shutter speed roughly 1/125-1/250s. The Moon is still reflecting a lot of sunlight at this point, and treating it like a bright daylight subject — because that's essentially what it is — keeps detail in the highlights instead of blowing them out.

Near maximum eclipse, once the Moon has dimmed and taken on its red cast: ISO 800-3200, aperture opened up to f/4-f/6.3, shutter speed slowed to 0.5-4 seconds. This is the phase most people get wrong, because the settings that nailed the earlier shot will produce an almost-black frame here. Check your histogram after the first few frames of totality and adjust up from there — don't trust the LCD preview alone in the dark, it lies.

A sturdy tripod is non-negotiable for both phases, but especially the slower totality exposures — even a stabilized lens won't save a half-second handheld shot of a subject this small in the frame. A remote shutter release or a 2-second timer avoids the shake from pressing the button directly.

What a Phone Can and Can't Do Here

A smartphone camera is genuinely capable of a good atmospheric eclipse photo — the reddish Moon low over a city skyline, a landscape shot with the eclipse as one element in a wider scene. What it can't do is resolve craters or surface texture on the Moon itself; the fixed, relatively short lens just doesn't have the reach. If the shot you want is a tight, detailed close-up of the eclipsed Moon, you need a DSLR or mirrorless body with at least a 300mm telephoto, ideally longer. If the shot you want is "the sky looked incredible tonight and here's proof," your phone is the right tool and you shouldn't overthink it.

Getting the File Ready to Actually Share

Eclipse photos live or die on their color gradient — the whole point of a blood moon shot is the transition from the sunlit rim to the deep red-orange of full shadow, and that gradient is exactly what gets destroyed by aggressive, repeated compression. A RAW file or high-resolution JPEG straight off a camera is often 15-40MB, which is too large to upload directly to most platforms without them re-compressing it themselves, usually badly, introducing banding across that gradient you spent an hour getting right.

1. Export from your editing software at full resolution first, don't downsize in-camera.
2. Compress once, deliberately, rather than letting five different apps each re-compress the same file as you share it around. Optimage's compress tool gets the file size down for upload without introducing the color banding a lower-quality re-save causes.
3. Convert to WebP for web posting if you're putting it on your own site or a gallery — it holds gradients better than a heavily compressed JPEG at the same file size. Optimage's convert tool handles that in one step.
4. Keep the original. Eclipse photos are the kind of image people want a genuinely good copy of years later, not just a phone-screen version — the next visible lunar eclipse from most locations isn't for a while.

If You're Building a Group Photo Set From Tonight

If your household, friend group, or local astronomy club all shot the eclipse from different spots, a shared photo set is worth more than everyone's individual camera roll. Set up a free shared gallery to pull everyone's shots into one compressed, organized place before they scatter across a dozen phones.

Summary

• The August 27-28, 2026 eclipse hit 96.3% coverage — visually a full blood moon despite the "partial" classification
• Bright phases need ISO 100-400/f8/1-125-250s; near-peak needs ISO 800-3200/f4-6.3/0.5-4s — check your histogram and adjust mid-shoot
• Phones handle atmospheric wide shots well; only a 300mm+ lens on a tripod resolves real lunar detail
• Compress your finished shot properly so the red-to-orange gradient survives the upload instead of banding
