Phnom Penh annular eclipse shooting skills Phnom Penh annular eclipse video

There are many ways to observe the annular eclipse: direct observation with eclipse glasses, telescope projection observation (for many people to watch at the same time, photography observation, pinhole imaging observation, etc.). With the popularization of digital photography technology, more and more fans want to film the process of annular eclipse. The following mainly introduces the shooting experience with a SLR camera.

Shooting "a series of images" of annular eclipse

The SLR camera is equipped with a wide-angle lens (such as 16 mm ~24 mm focal length lens), which is shot every 3-5 minutes from the initial loss to the recovery, and then superimposed by computer software (such as Startrails) to obtain a series of annular eclipse images and record the whole process of solar eclipse; In the whole shooting process, the position and orientation of the camera can't be changed, so it is necessary to do framing and composition in advance; Automatic timing shooting of programmable cable release; First determine the meal time, and then determine other specific shooting times according to the shooting interval; By choosing a unique landscape, you can get a unique "cross-image" work of annular eclipse.

Shoot a close-up of the annular eclipse.

Using a SLR camera with a telephoto lens (a lens with a focal length greater than 400 mm or an astronomical telescope) to take pictures at each time point of initial loss, lack of food, lack of food, light production and recovery, and obtain a series of photos at the key stage of the annular eclipse; Because the sun moves a long distance in the sky during the annular eclipse, the lens orientation should be adjusted every time to ensure that the sun is in the center of the camera's field of view.

Parameter setting

Manual mode is recommended for SLR cameras (the lens should also be set to manual focus mode. Typical exposure settings: shutter speed 1/500 seconds, ISO400, aperture F5.6, and specific parameters need to be determined according to field measurement. First, shoot the sun with typical parameters. If the sun is underexposed (the sun is dark), increase the exposure. If the sun is overexposed, reduce the exposure. During the whole eclipse, when the brightness of the sun changes obviously (for example, when the sun is in the eclipse stage or when the sun sets near the horizon), we should pay attention to adjusting the exposure parameters. At the same time, it is also recommended to focus accurately before shooting, adopt real-life mode, enlarge 10 times, and focus manually with the edge of the sun as the target.

Choose a tripod with strong stability;

The release of the cable is used to reduce the camera vibration caused by pressing the shutter by hand;

Storing files in RAW format can get more post-processing space than JPG format;

Prepare an extra set of memory cards and camera batteries.
