How to Photograph a Solar Eclipse:

Photographing a solar eclipse is a thrilling and challenging experience. Whether you’re an amateur photographer or a seasoned professional, capturing this rare celestial event requires preparation, technical know-how, and the right equipment.

Based on experiences from previous eclipses like the total solar eclipse of 2015 in Svalbard and the 2017 solar eclipse, this guide will help you get the most out of your eclipse photography.

Understanding Solar Eclipses:

When the moon moves in front of the sun, it can totally or partially obscure the sun’s light, causing a solar eclipse. Solar eclipses come in three varieties: annular, partial, and total. Different strategies are needed to capture each type, particularly when the sun’s corona is visible during a total eclipse.

Why Photograph a Solar Eclipse?

The visual spectacle of a solar eclipse is unparalleled. For photographers, it’s an opportunity to capture one of nature’s rarest events. From the dramatic phases of partial coverage to the breathtaking beauty of totality, photographing an eclipse allows you to document a moment that may only happen once in a lifetime, depending on your location.

Planning for the Eclipse Day:

Proper planning is critical for successful eclipse photography. It’s not just about knowing the time of the eclipse but also ensuring you are in the right place, with the right gear, and prepared for potential challenges.

1. Be Flexible:

When planning to photograph a solar eclipse, flexibility is key. Weather conditions, especially cloud cover, can easily disrupt your plans. Having multiple location options, such as a plan A, B, and C, can increase your chances of success. Mobility is also important, particularly in areas with limited access. For example, during the 2015 eclipse in Svalbard, the photographer’s ability to move was restricted by being on an island with no roads, emphasizing the importance of flexibility in planning.

2. Go Alone or With Close Companions:

While sharing the experience of a solar eclipse with others can be fun, it’s essential to choose your company wisely. Being in a large or noisy group may distract you from focusing on your photography. In Svalbard, the photographer was in a group with noisy, unruly children, which detracted from the overall experience. If possible, go alone or limit your company to those who understand the importance of focus during such a rare event.

Gear Preparation: What to Bring

The right equipment is vital for successful solar eclipse photography. Without the proper tools, your images might not capture the event’s full grandeur, and in some cases, you might even damage your gear.

1. Solar Filters: Essential Protection

Taking pictures of a solar eclipse requires the use of a solar filter. The sun’s rays are incredibly strong and can permanently damage both your eyes and your camera sensor. A specialized solar filter should always be placed in front of your camera lens during the partial phases of the eclipse.

Why Not Use ND Filters?

ND filters, even the strongest ones like the ND1000, do not provide sufficient protection against the sun. A dedicated solar filter is the only option to ensure your camera and eyes are safe. Because of their dependability, filters like the Baader AstroSolar® Safety Film 5.0 are advised.

DIY Solar Filter:

If you’re on a budget, you can create your solar filter by purchasing a sheet of Baader filter material and constructing a mount from cardboard. While this may not look as polished as a commercially made filter, it can work just as well when carefully constructed.

2. Know Your Gear in Advance:

Before the eclipse, practice with your gear. Understanding your camera, lenses, and filters ahead of time will prevent last-minute issues during the event. The photographer in Svalbard missed the first contact of the eclipse because they arrived late and had to tweak a solar filter in freezing temperatures. Avoid such issues by rehearsing your setup beforehand.

Best Lenses for Solar Eclipse Photography:

Your choice of lens will depend on the type of images you want to capture. For detailed shots of the sun’s corona, a longer focal length is recommended.

Recommended Focal Lengths:

A focal length of at least 600mm is ideal for capturing close-up shots of the sun during the eclipse. For example, in Svalbard, the photographer used a 500mm lens with a 1.4x extender, providing a focal length of 750mm. If you don’t want to crop your photos too much in post-processing, a long lens is essential.

Compact Cameras with Long Zoom:

If you don’t have access to high-end DSLR equipment, modern compact cameras with long zoom ranges can also produce impressive results. However, these still require a sturdy tripod to minimize vibrations.

Tripods: The Importance of Stability

A sturdy tripod is critical when photographing a solar eclipse, especially with long lenses. The tiniest vibration can ruin a shot, even when using fast shutter speeds.

During totality, slower shutter speeds will require even more stability.

Avoid Tripods with Center Columns:

For maximum stability, use a tripod without a center column. Center columns can introduce unwanted movement through the shaft, which can be detrimental to sharp eclipse photos.

Use a Remote Shutter Release and Mirror Lock-Up:

Consider using a remote shutter release to further eliminate camera shake. Combining this with mirror lock-up mode will help prevent even the smallest vibrations when taking close-up photos of the sun.

Focus on Infinity and Secure the Focus Ring:

Focusing your camera during an eclipse can be tricky. It’s advisable to pre-focus on infinity and then tape the focus ring to ensure it doesn’t accidentally shift during the event. This small step can prevent out-of-focus shots, especially when removing or replacing the solar filter during totality.

Arrive Early and Be Ready:

Don’t wait until the last minute to get to your chosen location. Ideally, you should arrive at least an hour before the eclipse begins. This gives you time to set up, troubleshoot any potential issues, and focus on enjoying the event.

Beating the Stress:

Arriving early prevents the kind of stress that occurred during the 2015 Svalbard eclipse, where the photographer arrived late and missed the first contact. Giving yourself extra time allows you to calmly prepare your gear and focus on the event rather than rushing under pressure.

Capturing Totality: Different Lenses for Different Views

Totality is the most magical moment of a solar eclipse, where the moon completely blocks the sun. During this brief period, you’ll want to switch between a long lens for detailed shots of the corona and a wide-angle lens to capture the environment around you.

Wide-Angle Shots:

While long lenses capture the corona’s intricate details, wide-angle lenses can capture the dramatic atmosphere of the surrounding landscape during totality. Don’t miss the opportunity to switch lenses and capture both perspectives.

Camera Settings: Bracketing and Exposure

Given the fast pace of a solar eclipse, particularly during totality, you won’t have much time to adjust settings. One way to ensure you capture the eclipse’s full range of light and shadow is by bracketing your exposures.

Why Bracket Your Shots?

Bracketing allows you to take multiple photos at different exposures, ensuring you capture all the details in the sun’s corona. This technique also enables you to create composite images later, combining exposures to reveal the full structure of the corona.

Post-Processing for Best Results:

After the eclipse, post-processing can further enhance your photos. By combining bracketed shots into a composite image, you can reveal intricate details that would otherwise be missed in a single exposure.

Safety Tips for Viewing and Photographing an Eclipse:

Safety is paramount when photographing a solar eclipse. The sun’s rays are powerful enough to cause permanent eye damage and can also destroy your camera sensor if not properly protected.

Eclipse Glasses and Filters:

When viewing a partial eclipse, always use eclipse glasses, and make sure your camera has a sun filter on it. Never use the viewfinder of your camera to stare at the sun without a solar filter on.

Remove the Filter During Totality:

During totality, when the sun is completely blocked by the moon, it’s safe to remove your solar filter. However, be ready to put it back on immediately after totality ends, as the sun’s rays will become dangerous again.

Enjoying the Moment:

While it’s easy to get caught up in photographing the eclipse, don’t forget to enjoy the experience. Totality only lasts for a couple of minutes, and it’s a unique moment that shouldn’t be entirely spent behind the lens. Take a few moments to soak in the view with your own eyes (safely, of course) and appreciate the event for its beauty.

Solar Filter for Phone Camera:

Capturing a solar eclipse with a phone camera requires a dedicated solar filter to protect both the lens and sensor. Without it, the sun’s intense light can damage your phone’s camera and produce poor-quality images. A solar filter blocks out harmful ultraviolet and infrared rays, allowing you to safely photograph the eclipse.

There are specially designed solar filters for phone cameras, which can easily clip onto the device, making it convenient for amateur photographers. Before the eclipse, test your setup to ensure everything works smoothly.
