What camera can take deep frames?

How does the camera capture the effect of depth of field? Is it related to the camera?

Ordinary ENG cameras can't produce the shallow depth of field effect you want to say.

Specifically, we can look at the relationship between lens depth of field and diffusion circle.

Simple and direct estimation: if the real focal length and aperture are greater than or equal to 60mm/ 1.8, you can feel it (generally, long-distance shooting, macro is not counted), and you should pay attention to whether it is equivalent focal length.

You think, just a few millimeters, or just a telephoto lens of 50-60mm (too far from the subject), how can you really shoot the effect you want?

Even if it is an APS-C format SLR video, the effect is just there (still depends on the lens), and the photosensitive target is much larger than that of the ENG camera.

To actually play Jiao Wai blur, the most basic camera at present is Sony VG 10, equipped with Zeiss large aperture lens, or Quan Huafu SLR instead of camera to play video, or ENG camera with focal plane converter and focal plane (or SLR lens).

Supplement: the effective way is to use red, but the price is too outrageous (not to mention Sony's digital movie camera)

At present, the technology of 1000* 1000 pixels has a speed reduction of about 4 billion times at one trillion frames per second. That's about 126.84 years, 3858 months and 46296.3 days. After watching the original 1 second long action ... it's really slow, and it can shoot the speed of light.

What is escalation shooting?

This is a technical term for making movies or TV, which is equivalent to slow motion, but please note that this is really not slow motion. Slow motion is to use software to lengthen the playing time of the original material in post-production and the picture will be played slowly. So what exactly is escalation shooting? Completely different from slow motion, it is a special technique of early shooting.

For example, if the normal shooting film is 25 frames, the camera will be adjusted to 200 frames when shooting is upgraded. At this time, the shooting will record the details more clearly (note that the details are captured, and the details cannot be captured in slow motion). When playing, it will play at normal speed, and the picture will move slowly, but it is very clear.

What kind of camera can be upgraded?

Here we take filming as an example. Many movies will have an upgraded version of slow motion, which is very gorgeous and delicate. So what kind of camera can take an upgraded lens? In fact, there are many kinds of cameras to choose from now. Today, I mainly introduce some cameras with upgrade function selected for low-cost movies, because for high-cost movies, there is no need to consider this problem at all, and the cameras they use are basically not equipped with ifs.

This machine is made in America. It is the first generation product of Red Company and also a classic product. Some people may not know much about redone camera, but the movies made with it are familiar to everyone. For example, Pirates of the Caribbean was made with REDONE camera. Upgrade shooting can be set perfectly. However, this machine also has some shortcomings, that is, it is a bit old, and the boot time needs tens of seconds. Now is obviously not suitable for this fast-paced working environment. If there is a cost budget, it is recommended to use its descendant product, Red Dragon, which is used by most domestic film or advertising practitioners, and the effect is self-evident.

What lens do you choose for clarity and depth of field? Master of photography or camera

Depth of field: If you have a tripod, try to shoot with a small aperture. I remember that when I photographed water droplets, the aperture of 85 focal length f 8 felt that the depth of field was still not deep. On a tripod, use a relatively small aperture, slow shutter or add lights.

Perspective distortion: this person feels that the focal length should be at least 85, but the longer the focal length, the shallower the depth of field, which needs to be compensated by the above-mentioned hand aperture, shutter lowering and lighting.

Lens: It is recommended to fix the focus. One is that the distortion is small, and the other is that the image quality is better than zoom. Since we want to shoot the product details, we will use a macro lens. Nikon's 402.8 is recommended, because 1 is cheap, compatible with the fuselage and not wasteful. The focal length of 2DX is 60mm, so it can advance and retreat. Your shooting distance is at most1.5m. This should be the macro head with the shortest focal length on DX. 3 Use macro, and the copy ratio is 1: 1. There is also Longteng's 60mmF2, which is also a macro head, which is more expensive and has a longer focal length.

18 105, 18 135, 1855, these heads are sleeves, which can only meet the basic shooting requirements. I think the difference is only in the focal length and whether there is anti-shake, and there is not much difference in details.

Please refer to 1 for depth of field. As you said, there is another way to increase the focal length. This cost is too high to be considered. If you are interested, you can check Baidu.
