How to Photograph a Solar Eclipse
Learning how to photograph a solar eclipse is part astronomy, part camera technique, and part safety discipline.
The right approach can help you capture the changing light, the crescent sun, and even totality without damaging your eyes or equipment.
This guide explains what to use, how to set up, and which mistakes to avoid so you can focus on getting clean, dramatic eclipse images.
What makes eclipse photography different?
A solar eclipse is not a normal landscape or wildlife subject.
The sun is extremely bright before and after totality, while the scene can become dimmer and cooler in color as the moon covers the solar disk.
That changing light affects exposure, focus, and composition in ways many cameras handle poorly without preparation.
Unlike moon photography, solar eclipse photography requires strict eye and sensor protection.
Pointing any optical system at the sun without proper solar filtration can permanently damage your camera sensor and can injure your eyes if you look through an unfiltered viewfinder or lens.
Essential gear for eclipse photography
You do not need the most expensive equipment, but you do need the right tools.
A stable setup and a solar filter matter more than a high megapixel count.
- Camera: A DSLR or mirrorless camera with manual controls.
- Lens: A telephoto lens is ideal, usually 200mm or longer for a close solar disk.
- Solar filter: A certified solar filter for the front of the lens, not a neutral density filter.
- Tripod: Essential for framing and consistent exposures.
- Remote release or intervalometer: Reduces shake during the sequence.
- Extra batteries and memory cards: You will shoot more than expected.
If you use a smartphone, it can capture the overall scene and the changing light, but it will not usually resolve the sun in detail unless attached to a telescope or telephoto rig with safe filtration.
Why a solar filter is non-negotiable
A certified solar filter blocks the dangerous intensity of the sun before the light enters the lens.
This protects your sensor, reduces glare, and makes it possible to focus on the sun’s edge and surface details like sunspots when conditions allow.
Do not confuse a solar filter with sunglasses, welding glass, or a standard camera filter.
Those are not designed for direct solar imaging.
The safest options are purpose-built solar filters from reputable astronomy or camera suppliers that meet current safety standards.
When should you remove the solar filter?
Only during the brief period of totality in a total solar eclipse, when the sun is completely covered by the moon and the corona becomes visible.
The filter must go back on immediately when any part of the sun reappears.
For partial phases, the filter stays on at all times.
Best camera settings for a solar eclipse
There is no single perfect exposure because the brightness changes dramatically from partial phases to totality.
Set your camera to manual mode so you can control shutter speed, aperture, and ISO without the camera constantly changing exposure.
- Mode: Manual
- Focus: Manual focus
- File type: RAW if possible
- ISO: Start around ISO 100 or 200
- Aperture: Often f/8 to f/11 for sharpness and depth of field
- Shutter speed: Varies widely depending on the phase and filter
Before totality, a solar filter usually requires fast shutter speeds to avoid overexposure.
During totality, exposure settings change dramatically because the corona is much dimmer than the filtered sun.
Bracketing several exposures is one of the best ways to avoid missing the ideal frame.
Suggested starting exposure approach
- Partial phases with solar filter: Start with very fast shutter speeds and adjust after test shots.
- Totality without solar filter: Use a sequence of exposures from short to longer to capture the corona’s structure.
- Landscape eclipse shots: Use a smaller lens and expose for the sky and foreground rather than the sun alone.
How to focus on the sun
Manual focus is more reliable than autofocus for eclipse photography, especially when the sun is filtered and tiny in the frame.
Many autofocus systems struggle with the lack of contrast.
Use live view, magnify the image on the screen, and carefully adjust focus until the sun’s edge appears as crisp as possible.
If your camera allows it, focus on the sun’s limb before the event and tape the focus ring in place to reduce accidental movement.
If you are using a telescope or super-telephoto lens, practice focusing on the moon at night before eclipse day.
The moon and sun are at effectively the same focus distance from Earth, so this is a practical rehearsal.
How to compose a stronger eclipse image
A tight solar disk can be compelling, but eclipse photography becomes more memorable when you think beyond a centered bright circle.
Consider the environment, the changing light, and what story your frame tells.
- Telephoto close-up: Emphasizes the sun’s shape and the corona during totality.
- Wide-angle landscape: Shows the darkened sky, horizon glow, and terrestrial context.
- Composite sequence: Records multiple partial phases in one frame or as a series.
If you want the eclipse over a landmark, scout the location ahead of time.
Use apps or planning tools to confirm where the sun will sit in the sky at the time of the event.
Common mistakes to avoid
Many first-time eclipse photographers lose images because they test too little or react too slowly.
Preparation is the difference between a useful sequence and a missed opportunity.
- Forgetting the solar filter during partial phases.
- Using autofocus and expecting it to lock on reliably.
- Setting exposure only once and not adjusting for totality.
- Not using a tripod, which leads to blur and framing errors.
- Checking the camera through an unfiltered optical viewfinder while the sun is visible.
- Trying to experiment with new gear on eclipse day instead of practicing beforehand.
How to photograph a solar eclipse with a phone
Smartphones can still play a useful role even if they cannot deliver detailed solar close-ups.
They are excellent for behind-the-scenes documentation, wide environmental shots, and time-lapse clips of the changing light.
For a phone-based eclipse setup, use a tripod, enable the highest quality capture mode available, and keep any solar viewing or magnification accessory specifically designed for safe solar observation.
Avoid improvising with random magnifiers or filters.
Simple eclipse-day workflow
A clear workflow keeps you calm when the sky starts changing.
Plan your steps before the event so you are not making decisions at the last second.
- Arrive early and set up the tripod, camera, and lens.
- Attach the solar filter before pointing toward the sun.
- Frame the shot and confirm manual focus.
- Take test shots and check the histogram for clipping.
- During partial phases, capture a few frames at regular intervals.
- As totality approaches, be ready to remove the filter only if the eclipse is total.
- Bracket exposures quickly during totality, then replace the filter immediately after the sun begins to reappear.
Editing eclipse photos after the event
Post-processing can improve contrast, color balance, and sharpness, but it should not rescue a badly exposed capture.
Shoot RAW so you have latitude to recover highlights and adjust shadows.
In editing software such as Adobe Lightroom or Photoshop, correct white balance, reduce stray glare, and apply modest sharpening.
If you captured a sequence, you can create a composite that shows the progression of the eclipse, but be transparent if the final image is a montage.
Planning for the next eclipse
Good eclipse photography rewards preparation long before the day arrives.
Check the path of totality, weather history, local regulations, and exact timing for your viewing location.
Practice with your camera on the moon, test your solar filter fit, and rehearse your exposure workflow so the real event feels familiar.
Once you understand how to photograph a solar eclipse, the process becomes much easier: protect your equipment, simplify your setup, and be ready for rapid changes in light.
The more you practice, the more likely you are to capture a sharp, dramatic image when the sky goes dark.
