Illustration of vr lens-steps of shooting and making VR panorama

How to evaluate VR painting and VR drawing? It can be said that the potential of VR painting and VR painting in creation is immeasurable.

But VR painting is only an iterative upgrade of painting tools, which enriches the choice of painting methods and the expression of artistic forms.

Although it lowers the difficulty threshold of achieving the same visual effect, it also puts forward higher requirements for the illustrator's artistic accomplishment such as modeling ability and three-dimensional space mastery, which is not a skill that every illustrator can easily master.

VR was originally used in the field of game and video design because of its "what you see is what you get, and its size and effect are intuitive enough".

Illustration, as a very inclusive major, has a cross-border with any major, and now it shows a trend of developing to VR painting.

Illustration design is not limited to plane hand-drawing, packaging, books, clothing, interactive interface animation, three-dimensional art installation and multimedia images, which is the most common cross-border form of illustration.

A solid 2D illustrator, after being familiar with VR tools, can use the logic of plane painting and some 3D thinking transformation.

Draw expressive 3D VR works to improve productivity and release creativity at the same time.

Generally speaking, with the development of science and technology, the development of VR painting will not stop, and will even continue to accelerate.

Shooting and making virtual reality panorama:

1. Select equipment and take photos:

At present, most individuals or practitioners use the wide-angle lens or fisheye lens of SLR cameras to shoot VR panoramas for enterprises in need, except for platforms such as Baidu Map, which are shooting VR panoramas with panorama camera. VR panorama is composed of multiple photos, so all angles must overlap when taking photos, so as to ensure better operation when stitching.

After finding a fixed point when shooting, when placing a tripod and a tripod head, be sure to check the details of the camera and the proportion of the tripod head, and then choose the number of shots with different focal lengths.

2, stitching, beautify the picture:

After shooting all the scenes, the exported pictures can be directly spliced in batches by software, or each scene can be processed separately by hand.

At present, most of the software for splicing pictures on the market are cracked versions of Chinese. If you want to learn, you can choose one of them, and then you can watch the tutorial to practice familiarity. The general requirement for stitching pictures is that the minimum resolution is 4000*2000, and the ratio is 2: 1. At this time, ps can be used to beautify the spliced pictures and modify the defective places.

3. Select the VR panoramic processing software platform:

The second step of stitching and beautifying the image is not a real VR panorama, and it needs to be uploaded to a professional VR panorama processing software or platform to see the effect. Jiushang VR cloud panorama production platform not only provides smooth online storage and sharing, but also provides the most basic class production function of VR panorama. For the special requirements of VR panorama, such as inserting perspectives, hotspots, sand tables, masks, music, videos and other functions, Jiushang VR cloud platform also provides these functions, which are unmatched by general free software.

After completing these three parts, basically a complete VR panorama will come out. After uploading to Jiushang VR cloud platform, you can also share the completed VR panorama with your friends. For professional practitioners, you can just share links and do a job with customers, or you can put them directly on the website.

What does the button above vr on Nikon SLR lens mean? "VR" on Nikon SLR lens refers to: camera anti-shake technology.

VR(VibrationReduction) is called camera anti-shake technology, which can be used for

Shutter speed

Take a quick shot when you lower the third gear, and when you use it,

telephoto lens

And you can get a clear picture.

The so-called "VR" is optical image stabilization, which is the abbreviation of VibrationReduction. It uses two sensors in the lens to detect vertical vibration (vertical shake) and left-right vibration (left-right swing) during shooting, and uses two VCM voice coil motors to drive the vibration compensation optical system to capture the camera data after vibration, which can compensate the camera shake by moving the lens.

Advantages of virtual reality:

1. The first application of Nikon damping technology is Nikon Zoom700VRQD, a light camera sold at 1994. It has a history of 10 years. According to different lens sensors, damping technology can be divided into virtual reality and VRII.

Virtual reality technology

Shutter speed can be effectively reduced by three levels.

2. The lens of the new VRII system can help photographers get the same stable shooting effect, even if the shutter speed is reduced by 4 levels. This is an epoch-making value.

3. More importantly, the effect of VR shock absorption can be observed through the viewfinder, and it can also work normally when shooting the subject in AF (automatic focusing mode).

4, for through the CCD

motion compensation

For a vibrating camera, the damping system can only be used after the shutter is released, so the damping effect cannot be seen through the viewfinder. If you don't see the effect, you don't know the result. In autofocus mode, the subject is still shaking. And using VR technology, even if

depth of field

Shallow, photographers can also correctly compose and focus.
