If you want to enjoy photographing the solar eclipse without needing to manipulate your phone without being damaged, then you should ask yourself some things in advance.
Astro-photographers (the professionals and enthusiasts who connect their giant cameras to telescopes) are likely to say that it is a mistake to try to get a high-quality photo with something that costs less than a thousand dollars. But it is possible to get a decent and memorable photo with what you have in your back pocket, an iPhone, Android or whatever.
Just do not pass up your desire to get that perfect Instagram image of an event that you may only be able to witness once in a lifetime.
Material you need
A smartphone tripod. The slightest movement, even a sneeze, could ruin a photo that could become perfect. You have to place the device on the tripod so you can set the timer (you can also use some sandbags, anything you use to avoid having to hold it with your hand will do you good).
A telephoto lens. The zoom lens of a cell phone is between 12x and 18x. There is also the zoom function of the phone, but it is a digital zoom which results in a lower quality image. Since you are trying to take a picture of a heavenly event that is far away, then give your phone a chance to take an excellent picture. These lenses cost between USD 20 and USD 40.
Solar filter. It is crucial for before and after the entire eclipse, when you see any part of the sun. If you do not have these filters, partial eclipse photos will not serve you. You can also use the built-in glasses in the eclipse glasses and place it in front of the camera lens.
Professional Advice: Practice it with the moon a couple of times before the eclipse.
1: This is the most important rule: Do not look at the sun! We all know we should not do it, but when an eclipse begins to occur we may be tempted to look without special glasses. Just doing a few minutes can be very harmful to your eyes.
2: Clean the lenses with a soft cloth
3: Place the sunscreen in front of the telephoto lens
4: Connect the telephoto lens to the front of the phone according to the instructions that accompany the lens.
5: Place the phone with your tripod in the direction of the sun (remember that the sun is going to move in the sky, so be prepared to change the position of the phone).
6: The dark sky will deceive your camera so that only a bright ball of white light is seen. You will need to adjust the exposure on your phone.
IPhone: Touch the screen to bring up a box, then swipe up or down to adjust the exposure.
Android: find the manual mode through the camera application and make the settings there.
7: Take the photos with the sunscreen during the partial eclipse. When the totality happens you can take the filter to take pictures because the moon will be blocking the sun. We recommend taking a couple of photos right now but do not get caught in the phone and see it with your own eyes because it may be the only time you experience a total eclipse.
8: When the sun comes out again, replace the sunscreen in the camera if you want to continue taking photos. Or remove it and enjoy the rest of the event if your phone.
