Yes. You can frame and trigger an eclipse photograph using a camera’s rear screen, an electronic display, or a remote control instead of putting your eye to the optical viewfinder. That choice only changes how you compose the image; it does not make it safe to point an unfiltered camera at the Sun. During any partial or annular phase, a special-purpose solar filter must be secured over the front of the lens or other optical system. NASA warns that bright sunlight entering camera optics without the correct front-mounted filter can cause severe eye injury and damage equipment. See NASA’s eclipse-viewing safety guidance.
The direct answer: use the screen or a remote, but filter the optics
An optical viewfinder is not the part of a camera that makes solar photography dangerous. The danger comes from the lens and any other optics concentrating the Sun’s light. You can therefore avoid the viewfinder completely and still take a photograph by using:
- the rear LCD screen on a DSLR or mirrorless camera;
- an electronic viewfinder viewed from a safe distance or a connected monitor;
- a phone’s screen; or
- a wired or wireless remote trigger after the composition is set.
None of those methods replaces a solar filter. NASA’s rule is explicit: “A special-purpose solar filter must be attached to the front of any telescope, binoculars, camera lens, or other optics.” Read the full wording at NASA Science’s Eclipse Viewing Safety page.
The practical distinction is simple: the viewfinder determines whether your eye is behind the camera; the front-mounted filter determines whether the camera’s optical path is safe.

What changes between eclipse phases and activities?
Protection depends on both what you are doing and whether the Moon completely covers the Sun’s bright face. The same camera setup is not automatically suitable for every phase.
| Situation | What remains visible | Required protection |
|---|---|---|
| Partial eclipse | Part of the bright solar face remains exposed | Use a special-purpose solar filter secured at the front of the camera lens or optical system. For direct viewing, use compliant solar-viewing glasses or a handheld solar viewer. |
| Annular eclipse | A bright ring of the Sun remains visible throughout the annular phase | Keep the special-purpose camera filter in place. The ring is still intense sunlight, not a safe totality. |
| Total eclipse before or after totality | The bright face is visible as the Moon moves into or out of totality | Use the front-mounted camera filter and eye protection as applicable. |
| Totality itself | The Moon completely obscures the bright solar face for a brief period | NASA describes a brief exception for unfiltered direct eye viewing during complete totality. The cited NASA material does not provide a camera-specific instruction to remove or reinstall a photographic filter, so do not assume the eye rule automatically applies to your camera. |
NASA also says to put eye protection back on as soon as any bright part of the Sun reappears. That instruction concerns your eyes; it should not be treated as permission to improvise with a camera filter.
Why eclipse glasses cannot be used as camera filters
Eclipse glasses and handheld solar viewers are designed for looking directly at the Sun. They are not substitutes for a filter engineered and mounted for a camera’s optical system. NASA specifically says not to use eclipse glasses or handheld viewers as camera, binocular, or telescope filters.

A camera lens can collect and focus far more light than a person would receive through unaided eyes. Holding a viewing card, a loose piece of filter material, or a pair of glasses over the lens can leave gaps, allow the material to shift, or fail to provide the optical protection the camera requires. The filter needs to be secured over the front of the lens or optical system, not placed behind the lens, over the eyepiece, or against the camera’s rear screen.
How to photograph without looking through the optical viewfinder
The following workflow keeps your eye away from the optical finder while preserving the essential solar-safety steps.
- Identify the optical path. Treat the lens, telephoto adapter, telescope, binocular attachment, or phone camera module as the part that needs protection. If the camera is attached to another optical device, the filter must protect the front of that system.
- Fit a purpose-made solar filter before aiming at the Sun. Secure it over the front of the lens or optical system. Check that it is the correct type and physical fit for your equipment; NASA recommends asking an astronomer for expert advice about filters for cameras and other optical devices. Its safety guidance is available at science.nasa.gov/eclipses/safety/.
- Choose a view that does not require your eye at the finder. Enable the rear display, use an electronic display viewed without pressing your face to the camera, or connect a remote monitor if your camera supports one. A phone is framed from its screen by design.
- Set the composition while the filter is installed. Keep the filter on while pointing the camera toward the Sun during partial or annular phases. Do not remove it merely because you are using the LCD instead of the viewfinder.
- Trigger the exposure without looking through the finder. Use the shutter button while watching the screen from a safe position, or use a wired or wireless remote. A remote reduces camera shake and lets you stand clear of the optical axis, but it is not a filter.
- Monitor the setup rather than the Sun with your eyes. Watch for the camera’s warnings, framing changes, or a filter that has shifted. If the filter becomes loose, stop aiming at the Sun and correct the mounting before continuing.
- Recheck protection whenever the phase changes. Partial light returns immediately after totality. Restore the required eye protection and ensure the camera’s filter arrangement is appropriate before continuing to photograph.
This approach answers the viewfinder question directly: you can compose and fire the shot without placing an eye behind the camera. It does not change the optical-safety requirement.

Photographing partial and annular phases
Partial phases
During a partial eclipse, some bright solar surface is exposed at all times. Keep the special-purpose solar filter attached to the front of the camera optics for the entire photographic session. The rear screen is useful for composition, but its presence does not shield your eyes from light that may escape around an incorrectly mounted filter, nor does it protect the camera sensor or lens.

An annular eclipse leaves a brilliant ring of sunlight around the Moon. Because the bright face is never completely covered, treat the annular phase as a filtered-photography event from start to finish. Do not use the short period of maximum annularity as if it were totality.
Direct viewing while operating the camera
If you look away from the screen and toward the Sun, use proper solar-viewing glasses or a handheld solar viewer. Do not alternate between unprotected glances and screen-based photography. The safe viewing accessory for your eyes and the safe filter for your camera are separate pieces of equipment.

What to do during totality
NASA identifies a narrow eye-safety exception: during totality, when the Moon completely obscures the Sun’s bright face, direct viewing without eclipse glasses is possible for that brief interval. Eye protection is required during the partial phases before and after it, and must go back on as soon as any bright part of the Sun returns. NASA explains this distinction in its eclipse safety guidance.
That exception should not be converted into a camera instruction. The NASA pages cited here do not state when a photographic solar filter may be removed from a camera lens or when it must be replaced during totality. Unless you have equipment-specific, expert guidance for your exact camera and filter, leave the photographic filter arrangement unchanged and follow the manufacturer’s instructions. Never infer camera safety from the fact that your eyes can briefly view totality.

Can a smartphone photograph an eclipse?
Yes, but a smartphone also needs a specialized eclipse filter between its camera and the Sun. NASA answers the smartphone question directly in its Total Solar Eclipse FAQ. The phone’s built-in screen does not remove the need for that filter.
For a phone, the practical sequence is:
- Install a filter designed for the phone’s camera module and secure it so it cannot slide away while the phone is pointed upward.
- Open the camera app and compose from the screen rather than trying to look along the phone’s body.
- Keep the filter in place during partial and annular phases.
- Use a timer or remote shutter if available to reduce movement, while remembering that a timer is not a solar filter.
- Follow the same caution about totality: the eye-viewing exception does not establish a phone-camera filter rule.
Do not hold eclipse glasses over a phone camera and assume the camera is protected. NASA’s warning against using direct-viewing products as camera filters applies to smartphones as well.
How to choose and verify a camera solar filter
Filter choice is equipment-specific. A filter that fits one lens diameter or optical arrangement may not fit another, and the fact that a material looks dark is not proof that it is suitable for solar imaging. NASA advises seeking expert advice from an astronomer about filters for cameras and other optical devices.
Recommended Free Tools
- Verify the optical device: identify whether you are filtering a standalone lens, a phone module, or a camera attached to a telescope or binoculars.
- Verify the mounting point: the filter belongs at the front of the optical system, where it prevents concentrated sunlight from entering the optics.
- Verify the fit: the filter must remain secured while the camera is moved, tilted, or operated remotely.
- Verify the instructions: use the filter according to its maker’s equipment and handling directions, and obtain specialist advice if compatibility is unclear.
NASA does not approve any particular brand of solar viewer, so a product should not be presented as NASA-endorsed merely because it is marketed for an eclipse. NASA’s safety page is the authoritative starting point for the protection principle.
Common mistakes and what to do instead
| Mistake | Why it fails | Safer correction |
|---|---|---|
| Using the LCD screen without a front filter | The screen changes framing, not the amount of sunlight entering the lens. | Attach a special-purpose solar filter to the front of the optics before aiming at the Sun. |
| Putting eclipse glasses over the lens | Direct-viewing glasses are not camera filters and may not cover or secure the optical path. | Use a camera-specific front-mounted solar filter. |
| Filtering only the viewfinder or eyepiece | Light can still enter through the camera lens and be concentrated inside the camera. | Filter the front of the lens or other optical system. |
| Removing protection because totality is near | The bright photosphere is still visible before and after totality, and the cited guidance does not authorize a camera-filter change. | Keep eye and camera protection decisions separate; restore eye protection immediately when brightness returns. |
| Assuming a remote shutter makes the setup safe | A remote only triggers the camera and does not reduce solar energy entering the optics. | Use the remote together with the correct front-mounted filter. |
| Relying on a loose or improvised filter | A gap or movement can expose the optical path and invalidate the protection. | Stop, move the camera away from the Sun, and securely fit equipment-specific solar protection. |
A concise safety checklist
- Am I photographing a partial or annular phase? If so, is a special-purpose solar filter secured at the front of the camera optics?
- Am I using eclipse glasses only for my eyes, rather than treating them as a lens filter?
- Have I enabled the rear screen, remote display, or remote trigger so I do not need the optical viewfinder?
- Is the filter suitable for this exact lens, phone module, telescope, or binocular attachment?
- Have I avoided assuming that the eye-viewing exception during totality also applies to the camera?
- Will I put eye protection back on as soon as any bright part of the Sun reappears?
