Can You Take a Picture of the Eclipse? When Can You Look at the Eclipse Without Glasses?

As the much-anticipated solar eclipse of April 8, 2024, draws near, millions of Americans are gearing up to witness this celestial event. However, amidst the excitement, questions arise about the safety of viewing and capturing the eclipse, particularly concerning the use of cameras and smartphones.

The allure of capturing the rare spectacle with one’s own device is undeniable. Yet, experts warn that without proper precautions, both eyes and equipment can be at risk.

Dr. Nitin Kumar, a senior staff ophthalmologist at Henry Ford Health, emphasizes the critical importance of protecting one’s eyes during the eclipse. He likens the effect of direct sunlight on the retina to using a magnifying glass to focus sunlight on a surface, causing thermal damage to the cells responsible for vision. This damage, known as solar retinopathy, can have lasting consequences, including blind spots or distorted vision.

But what about capturing the eclipse through a camera or smartphone lens? According to NASA, the image sensor of these devices is susceptible to damage when pointed directly at the sun, much like the human eye. The agency advises utilizing proper filters, such as ISO-certified ones, to protect the equipment.

So, can you take a picture of the eclipse safely? The answer lies in following strict safety guidelines. The American Academy of Ophthalmology stresses that sunglasses, welding goggles, or homemade filters are not adequate protection. Only specially designed solar filters or eclipse glasses that meet the ISO 12312-2 international safety standard should be used.

But what if you want to use your smartphone to capture the eclipse? NASA suggests holding eclipse glasses in front of the phone’s lenses when photographing the sun, except during totality when the sun is completely covered by the moon. During totality, it is safe to view the eclipse without glasses or filters, but this phase is brief, lasting only a few minutes, and caution must be exercised as the sun re-emerges.

For those unable to access proper equipment or concerned about the risks, there are alternative methods to experience the eclipse safely. Many organizations offer live streams of the event online, allowing viewers to observe without direct exposure to the sun’s rays. Additionally, simple pinhole projectors can be created using household items, providing a safe way to indirectly view or capture the eclipse.
