Excuse me, how was the 360 panoramic photo taken?

Panoramic photos are actually taking pictures and putting them together with PS.

Skills of taking 360-degree panoramic photos;

In the process of panoramic production of 1 and 360, exposure compensation of 1 ~ 2 files (which can be used in P, TV and AV formats) is added on the basis of the original photometry according to the intensity of scenery light. M file can improve ISO to obtain exposure compensation directly (advantages: it can ensure the initial value of aperture shutter combination; Hazard: image quality degradation).

2. Adjust the focal length of the fisheye lens to the longest focal length, and measure the light as close as possible to the main body, then determine the exposure value measured at this time, and then take pictures from the original composition as required.

3.360 panoramic production In the case of backlight, strong light enters the lens, resulting in the subject blackening. At this time, forced light can be used to fill the subject (for example, during the day, strong light is needed to fill the light, the aperture is blurred, and the synchronization speed of strong light is low, so a medium gray (nd) filter is needed to reduce the light of the lens).

4, 360 panoramic production light is too messy, you can use the peripheral exposure method to take photos and take multiple photos, so that you can get three photos of overexposure, normal exposure and underexposure, and then choose the best Zhang Baocun.

5. When taking photos against the light, be sure to use a hood, try to avoid direct glare on the lens, remove unnecessary filters and avoid glare.

6, you can contact a variety of photo tips. Such as exposure compensation and forced illumination.

7. If the 360 panoramic production is really overexposed, it can be post-processed by processing software (if the overexposure is serious, it can only be a photo fault and cannot be compensated).

8, 360 panoramic production If you want to get the silhouette effect, you only need to take photos directly according to the measured exposure value of the camera.

9 key issues (such as the technical quality of gambling films, etc.). ) are the quality of backlight photography, the removal of key elements of photography, the description of lens and the level of license.

360-degree panorama is to simulate an interactive and illusory three-dimensional space scene through technology or equipment. Nearly 40 years have passed since Sutherland 1965, the father of 360-degree panorama, first put forward the basic idea of virtual reality system in a paper entitled Ultimate Display.

Until four or five years ago, the application of virtual reality was limited to some high-end industries. With the development of digital image technology, with the gradual popularization of 360-degree panorama as a breakthrough, image-based virtual reality technology has gradually emerged. 360-degree panorama has attracted more and more attention because of its strong sense of reality, depth of 360-degree panorama, convenience and quickness.

Advantages:

1, strong sense of reality, based on real pictures, more realistic than other modeling objects.

2. It can express more image information than plane pictures, can be controlled at will, and has good interactive performance.

3. Through the perspective processing of the image, the real three-dimensional real scene is simulated, which has a strong sense of immersion and brings an immersive feeling to the viewer.

4, convenient production, short production cycle and low production cost.

5, the file is small, the transmission is convenient, it is suitable for network use, and the release format is diverse, which is suitable for various forms of applications.

6. HD: After continuous development and improvement, we have higher definition and resolution than the pictures provided by our peers while ensuring the playback speed and window size. The highest resolution of the picture can reach12.5 million pixels; The maximum window can reach1024× 768;

7. Suspension technology: get rid of the shackles of tripods, break the conventional imagination restrictions, and create a brand-new perspective, with a foothold rising into the air and no supporting points around. Especially from the perspective, it presents a steep, spectacular and unique sensory effect;

Geospatial information visualization is an important technology in information visualization, which completely reproduces the real situation in the management environment, puts all the management objects in a real three-dimensional world, realizes data visualization, and truly achieves "what you see is what you get" in the management sense.

360-degree panoramic technology provides a unique method for recording phenomena, discovering laws and predicting results. The application fields involved include human-computer interaction, geographic information, engineering management, environmental simulation, medical diagnosis, agriculture and forestry management, etc.
