There are several smartphone apps for iPhone and Android that claim to enhance your device's photo abilities, and you should consider testing as many of them as you can before the eclipse.
Don't count on your phone's autofocus to do this. Then, keeping your finger pressed on the screen, swipe up or down to adjust brightness. Tap the screen and hold your finger on the image of the moon to lock the focus. With most smartphones, you can adjust the focus and exposure with your fingertips. NASA recommends that smartphone users practice photographing the full moon before the eclipse to learn how to manually adjust focus and to get an idea of how large the eclipsed sun will appear with your camera lens. "NASA makes no recommendations about how to safely photograph the partial eclipse phases because of the huge number of optical filter and camera models that may potentially be used and often with unsafe outcomes." Practice makes perfect
"Using optical filters to photograph the eclipse when you are not on the path of totality is inherently risky because you are looking at the blindingly bright solar surface," NASA says in its guide to photographing the Aug. Remember, you'll have only 2 1/2 minutes or less to take photos.Īs a precaution, you should keep special solar filters, eclipse glasses or handheld solar viewers over your eyes at all times when looking at the solar eclipse. When totality begins, remove the glasses or the filter from the lens and shoot normally with the camera.
Or buy a solar photography filter for the moments before and after the phase of totality, when the sun is still blinding.
In addition to having ISO-certified eclipse glasses to protect your eyes, be sure to have an extra pair to cover your smartphone or digital camera lens. Unprotected direct exposure to the sun can cause permanent damage to your eyes, and the same is true for your camera lens, according to NASA. You never want to look directly at the sun with your naked eyes, except during the brief totality phase of the eclipse, when the moon entirely covers the sun's beaming face.
