360-degree panorama, how to take pictures and splicing?

First, put the camera in place, check the tripod and pan/tilt to see if there are any loose screws, the scales are aligned and the camera is in a horizontal state. Then, turn on the camera and tilt it down 15 degrees. If it's an 8mm fisheye lens, you don't have to tilt down 15, just shoot horizontally.

Second step

Photometry. Adjust the camera aperture, iso and shutter parameters to see if the focus is accurate. If you think the photos are a little overexposed, you can reduce one or two exposures, otherwise you should increase the exposure until the exposure is appropriate. When measuring light, be careful not to backlight.

The third step is white balance. Adjusting the white balance (color temperature) of the camera is not much different from what the eyes see. Then make a mark with your hand gesture, which is convenient for sorting out the pictures later.

Fourth step

Surround exposure mode. HDR photography generally adopts the method of surround exposure, which is used when the dynamic range of the scene exceeds that of the camera. Usually, the exposure is surrounded by three frames, and the exposure value interval is 2EV, and the dynamic range can reach about half of that of a camera. Adjust the ambient exposure mode to (3F.

2.0)。

Step five

Rotating shooting. Turn the pan/tilt dial to 0 degrees, take three shots, turn to 60 degrees to take three shots, then turn to 120 degrees to take three shots, and so on. Take a group of three shots every 60 degrees, a total of six shots, and then rotate the pitch axis to make the camera shoot three shots vertically in the sky, which is to complete a process.

Look back at the 2 1 photo taken to see if there is any need to make up the photo. If the pattern directly below the tripod is complicated and irregular, move the camera and take a group directly below.

It is enough to shoot four groups horizontally with an 8mm fisheye lens, that is, shoot one group at 90 degrees.
