Panoramic photo shooting skills

Before the emergence of digital imaging technology, there were two ways for people to get panoramic photos: using special panorama camera rotation shooting or professional darkroom division to manually splicing, which was difficult for ordinary photographers to do. The "panorama" boasted by APS camera only uses the large angle of view of super wide-angle lens. Strictly speaking, it is more appropriate to call it "overlay photo". The popularity of digital cameras and digital image processing technology makes panoramic photography easy. Anyone who has a digital camera and a computer that can run image processing software can try to take panoramic photos with amazing angles.

Shooting point

There are certain requirements for panoramic photo stitching, such as similar exposure value, similar tone, sequential arrangement, and slight overlap with each other. There are some precautions when shooting.

First, the choice of focal length.

Some people think that when taking panoramic photos, the viewing angle should be as large as possible, so the shortest focal length (wide-angle lens or wide-angle end of zoom lens) should be used, so the number of photos spliced is less. In fact, this is a misunderstanding. It saves trouble when shooting and saves trouble when sewing. Because the wide-angle lens has a strong perspective effect, especially at the edge of the picture, it is easy to distort and it is difficult to achieve seamless stitching. But wide angle has the advantage of wide angle, which can form a stronger sense of perspective. For example, the above picture is a work shot by CANONE EF 17-40 mm, and the film has a strong sense of perspective besides panoramic perspective.

Therefore, you can use the medium focal length or telephoto end with small deformation when shooting, and it is not appropriate to change the focal length in the middle of shooting. Commonly used lenses are EF35mm, EF50mm and ef 85 mm. The picture above shows the medium telephoto panoramic patch of mike2009.

Second, the exposure parameters

Many digital cameras have a special panoramic mode. In this mode, the camera will automatically set the exposure parameters according to the requirements of taking panoramic photos. For cameras without panoramic function, the following points should be noted:

Do not change the aperture, speed, ISO, resolution and other settings.

A. Average metering is used for metering, and manual exposure or AE lock is used to lock exposure parameters during exposure. Settings such as aperture, speed, ISO, resolution, etc. cannot be changed during the shooting of the same group of panoramic photos;

B, use fixed white balance, using automatic white balance may cause different tones of photos.

Third, the shooting method

When shooting in a certain order (from left to right or from top to bottom, etc. ), it is best to use a tripod to rotate smoothly. Pay attention to the vertical axis when shooting in rotation. When shooting left and right or panning point by point, pay attention to the same camera height and angle. Generally, do not use flash, which will cause low light and far darkness. There must be an overlap between two adjacent photos when shooting. Some digital cameras of Canon, Casio and other brands have auxiliary prompts on LCD screens in panoramic mode. Avoid shooting when the light conditions change dramatically (such as clouds covering the sun), so as to avoid too much difference in screen exposure. When shooting, you should also pay attention to avoiding moving objects (such as vehicles and pedestrians) at the joints. Although choosing a clearly marked position as the splicing point is conducive to the identification and splicing of some automation software, we still suggest choosing a position that is not clearly marked and easy to mix as the splicing part, such as water surface, distant mountains, etc., so that it is not easy to see the seams when splicing.

Seamless splicing

1. Prepare a tripod.

2. Adjust the white balance of the camera to cloudy. If set to automatic, the white balance in each photo may change, so the effect of the photo will be different.

3. It is best to shoot vertically, because it can avoid edge deformation more than horizontal shooting.

4. Each photo overlaps to 20%, ensuring that 1/4 of each photo appears on the second photo, which is beneficial for photoshop to overlap good photos.

Mark the first photo and the last photo, so that you know where to start and end shooting.

6. Buy a cable releaser, which can be used for taking selfies. And there is no jitter when taking pictures.

7. Shoot as fast as possible, because if there are clouds moving or the light changes, you should capture the picture quickly to ensure that the picture content will not deviate too much. Panoramic photography of ocean waves is the most difficult, and it is difficult for fleeting ocean waves to get neat photos through high-speed continuous shooting. The picture below shows the bronze prize work of Epson Panoramic Photography Competition, a panoramic view of the waves.

Fourth, creative shooting.

In short, creativity can make photos more interesting when you have the technical operation ability!
