IPhone photography skills: how to take photos of Gao Fancha?

The so-called Gao Fancha is that there are many differences between the brightest place and the darkest place in a photo. Usually, even the photosensitive elements of the camera can't be captured in the same picture at the same time, so the photos taken are either too dark or too bright. If you use one eye, you can use a black paper card to shade the over-bright place, so that the picture can complete different exposure conditions. The power of this application is that when the shutter is pressed, two photos with different exposure conditions are directly taken as the brightest and darkest, and automatically combined into one. You should pay attention to the interval between two photos about 0.5 seconds to avoid shaking your iPhone. As for attention, framing, composition, and what photographic equipment to use should also be paid attention to. In addition, the next three photos (6~8) use the slow shutter to create a dreamy feeling when the waves beat the coast.

Pay attention to the same thing. Keep your hands steady, or a stationary object will definitely cause a shaking afterimage. To some extent, the fun and convenience of taking photos on iPhone is incomparable with monocular cameras. After all, I'm always embarrassed to run around with a big monocle on my back during office hours, so it's very interesting how to take a photo of Gao Fancha with an iPhone that people think was taken with one eye. Try it if you are interested, and the effect will surprise you greatly!
