What gear you need to photograph a solar eclipse

The gear list for eclipse photography is short, and none of it is exotic. What separates a usable set of frames from a wasted afternoon has less to do with which camera you own and more to do with two decisions: filtering correctly, and bracketing wide enough during totality. Here's what each piece of gear does and why.

The solar filter

A certified solar filter mounted on the front of your lens is the one non-negotiable item. It blocks the Sun's visible and infrared output to a safe level for both your eyes and your sensor during every partial phase, before and after totality. Buy a filter rated specifically for direct solar viewing or imaging. Sunglasses, welding glass of unknown grade, or exposed film are not safe substitutes. The filter mounts on the front of the lens, not behind it, and it comes off only during totality, when the Sun's disc is fully covered by the Moon. Put it back on the instant the first bright sliver of the Sun reappears (the "diamond ring"). Outside of totality, an unfiltered lens pointed at the Sun can permanently damage your eyes if you look through an optical viewfinder, and can damage your sensor either way.

The camera body

Any camera with a manual exposure mode works for this: a DSLR, a mirrorless body, or a bridge camera with a long built-in zoom. What matters is that you can set shutter speed, aperture and ISO by hand and lock them, because the auto-exposure modes on most cameras will actively fight the bracket you need to shoot (more on that below). Sensor size and resolution matter less than people assume. A competent exposure bracket from a modest camera beats a poorly exposed set from an expensive one.

Focal length: disc vs landscape

This is really two different photographs, and it's worth deciding which one you're going for before the day. For a corona that fills a meaningful part of the frame, you want 200mm or longer on a full-frame sensor (proportionally less on a crop sensor, since the crop factor multiplies your effective reach). For a landscape shot, say the eclipsed sky sitting over a horizon or a crowd silhouetted against the darkened sky, a wide-angle lens in the 14-35mm range is the right tool. A solar filter isn't even needed for that shot once totality begins, since the Sun's disc is far too small in the frame to matter. If you have two camera bodies, shooting both is common; with one body, decide which photo you actually want more.

Tripod

A stable tripod is essential at 200mm+ focal lengths, and it matters for a second reason too: registering (aligning) a bracket afterward is done against the edge of the Moon's disc, and that only works cleanly if the frame hasn't been reframed mid-sequence. Set your composition once totality is close, lock the tripod head, and don't touch it again until totality ends.

Why totality needs a bracket, not a setting

This is the part that trips up almost everyone shooting their first total eclipse, and it's worth understanding rather than just following a checklist. During totality the corona is visible: the Sun's outer atmosphere, streaming outward from the now fully covered disc. That corona has an enormous brightness range. The inner ring near the Moon's edge is blindingly bright compared to the faint, wispy outer streamers reaching several solar diameters out. No single exposure can hold both ends of that range. Expose for the bright inner corona and the outer streamers turn pure black; expose for the streamers and the inner ring becomes a featureless white blob.

The fix is to shoot a series of exposures spanning that whole range, a bracket. As a floor, plan for at least six stops of range: something like 1/1000s at the fast end and 1/15s at the slow end, with the aperture and ISO held fixed across every frame and only the shutter speed changing. Wider is better if totality length allows it; six stops is the minimum that gives merge software something real to work with. This isn't a preference, it's physics. A narrow bracket, or a single "safe" exposure, can't be rescued afterward by any amount of processing, because the missing brightness range was simply never recorded. Whatever gets left out of the bracket during those two minutes is gone for good.

A few settings to lock down before totality: turn off auto-exposure, auto-ISO, auto-brightness, and any in-camera HDR or night mode. All of these will try to "helpfully" clip your frames toward a single brightness and defeat the bracket. Fix your aperture and ISO once, and vary only the shutter speed through the sequence.

RAW vs JPEG

Shoot RAW if your camera supports it. It preserves the most tonal range per frame and gives the widest safety margin when merging. But don't let a JPEG-only camera stop you: a well-shot JPEG bracket, with auto-tone and in-camera processing turned off, still merges into a good result. The bracket's width matters far more than the file format it's captured in.
