1920 photography

Microfilm 1920× 1080, frame ratio 16: 9. There is no need to press the black edge up and down.

Microfilm A film projected on a screen, whose aspect ratio is greater than that of the standard 35mm ordinary film (1.375: 1). Its aspect ratio is generally between 1.66: 1 and 3: 1, and its screen width is between 10 and 20m. The screen is slightly curved to broaden the audience's horizons.

After that, a recording position (vocal cord) should be reserved in the film hole of 35 mm film, so the picture area of silent film has to be compressed, and the width and height of the shot picture are changed to 22 mm× 16 mm, and the projection gate is 20.9 mm× 15.2 mm, that is, the aspect ratio of the picture projected on the screen is changed to 65438.

Microfilm shooting skills:

1, shooting horizontally

Most of the pictures should be taken horizontally by the camera, which is more in line with people's visual habits and the picture effect is relatively peaceful and stable.

Step 2 shoot from bottom to top

Photographs taken from different angles convey different information. The same thing will have different psychological feelings because of different perspectives. Looking up at a target, the viewer will feel that the target seems to be particularly tall, whether it is people or scenery. If you want to make the image of the subject look higher, you can lower the shooting angle of the camera and shoot obliquely upwards. This kind of shooting can strengthen the dominant position and make the subject look more majestic and tall.

Step 3 shoot from top to bottom

The camera position is higher than the subject, and the lens is tilted downward to shoot. Ultra-high angles are usually used to display scenes in combination with ultra-far pictures. It can be used to shoot big scenes, such as street scenes and ball games. It is easy to show the layering and depth of the picture when shooting with panoramic view and medium lens.

Step 4 shoot from the perspective of the object

The reflection of perspective should conform to the habit of normal people to see things. Sometimes, it may be necessary to show the perspective of the subject. In this case, no matter whether the shooting height is high or low, you should shoot from the eye height of the subject.
