Hybrid Solar Eclipse 2023: how to take a good photograph and what precautions should I take?

The photographs in the solar eclipses they can be very hard to come by. In addition to the change in light during the astronomical event, a camera is needed that allows us to correctly capture what we want, but the user must also be careful and use the corresponding tools.

For starters, users should not use their cell phones to create these photos. This is because Camera lenses need a sunscreen to prevent the powerful light from damaging the photographer’s eyes.. This is very important, because regardless of whether the sun is 99% covered, that 1% could cause vision problems and even blindness. Thus, It is also essential that users wear glasses that protect them from sunlight.

These solar filters are safe to use on both camera lenses and telescopes. These can be achieved as “off-axis” or “full aperture” filters.. These fit the lens, so the user will not have to worry about them at any time. After taking these precautions, and putting on sunscreen, users can take pictures.

How to take the best photograph during a solar eclipse?

As mentioned before, to take these types of photos, you need a camera with a sun filter. Thus, You cannot use a cell phone, no matter how advanced your photography system is. It is not even recommended to use these filters on a smartphone, since they are not designed for this device.

On the other hand, some basic knowledge about photography is necessary, since there will be enough light on the lens of our cameras. According to Nikon, obviously, the longer the lens length, the larger the eclipse picture can be taken. In addition, it is best to use a digital camerabecause we can rely on technology to take the photo at the perfect moment.

Set up the tripod and perform a calibration when the sun is not yet eclipsed. Thus, according to the company, you will determine the exposure and, with a digital camera, it will be done almost immediately. Even in this phase, sunscreen and sunglasses should be used.

Then, aim for the midday sun at a fixed aperture. You can choose an aperture between f/8 and f/16 with each shutter speed from 1/4000 second to 1/30 second. By having so much light, you will always have a great speed to capture the image. “Look at the exposures and choose the best combination of shutter speed and aperture. Use it to photograph the partial phases of the solar eclipse. LThe camera’s histogram function is an excellent way to assess the best exposure”, says the company.

The histogram cannot be fixed, but must fall towards the upper end of the brightness values. No matter how much during the eclipse the Moon covers the Sun in parts, the light that the star emits is the same. “You can choose bracket exposures to ensure you photograph the solar eclipse with a perfect exposure. If you are testing on a sunny day and the eclipse occurs on a cloudy day, increase the exposure bracketing by an additional f/stop”, he adds.

If you want to perform the perfect photo when the pearly white corona, red prominences and chromosphere of the sun are visible; You must be prepared, as this part could last a few seconds or minutes. “During the total phase, all sunscreens must be removed. This is because the sun’s corona has a surface brightness a million times fainter than the visible disk of the Sun or photospherethen the crown photographs should be taken without the filter”, indicates the company.

The company even points out that it is safe to see the sun without protective glasses, but we must bear in mind that we do not know exactly how long this moment will last. Therefore, it is best to be cautious and maintain this eye protection.

Finally, users must be attentive to take the photo, as the event could distract them. “The best strategy is to choose an aperture and bracket exposures on a range of shutter speeds from 1/100 second to 1 second.. You should try the actions of setting up the camera and adjusting the exposures because it is common for photographers to get distracted by seeing this phase of the solar eclipse and forget to take the photos.”, he concludes.
