How fast the shutter speed is considered a high speed shutter

There is no uniform standard; In order to ensure that the ** shoot will not be weak, it is generally necessary to ensure the shutter speed.

Safety shutter in 1 60s or more.

When shooting, there is often a blurry picture, which is often caused by the fact that the shutter speed during shooting does not reach the safe shutter, and the shaking of the hand will be directly reflected in the **, resulting in a false shot.

To put it simply, the safety shutter is usually a boundary line of the slowest shutter that does not blur the film, and in the actual filming process, there is no numerical calculation in the strict sense, when using a certain shutter, as long as the film is not blurred, the shutter speed can be called the safety shutter.

There is no absolute statement about this, but there is a "safe shutter" statement, in order to ensure that the ** shoot will not be empty, it is generally necessary to ensure that the shutter speed is more than 1 60s.

But the safety shutter is not static, it is closely related to the focal length of the lens used. The safe shutter speed is the reciprocal of the focal length, i.e. the safe shutter speed = 1 focal length. If a 50mm lens is used on an APS-C camera, then 1 80s is a safe shutter.

If you choose a shutter speed of 1 125 seconds or 1 250 seconds, you can ensure the stability of the shooting. On the other hand, if you choose a shutter speed of 1 30s, there is a possibility that there will be a "false shot".

When shooting sports themes, more than 1,200 seconds can be regarded as a high-speed shutter.

Shoot dynamic flowing water effects at least 1 15 seconds, or even slower (say 1 5 seconds).

For example, if you want to shoot water droplets, the speed should be at least 1 2000 seconds, or even faster (such as 1 4000 seconds), such as shooting night scenes, mainly depending on the lighting conditions at the time, the speed is generally 1 5 or slower.

The focal length of the shooting is 80, so in order to ensure that ** is not blurred, you need to use at least 1 80 seconds of shutter. Under normal circumstances, the speed of 3 1 2000 is enough for normal use.

There is no such thing as a prescribed one.

I think that more than 1,1000 seconds can be counted as a high-speed shutter.

According to the "high-speed synchronization" of the flash, more than 1 200 seconds should be considered a "high-speed shutter".

The shutter is a device used in camera equipment to control the time when light hits the sensor. It is an important part of the camera. So do netizens know what the camera shutter speed is? Interested netizens, let's find out together.

1. The maximum shutter speed of the professional 135 camera reaches 1 16000 seconds.

2. Common shutter speeds are: 1 1 2 1 4 1 8 1 15 1 30 1 60 1 125 1 250 1 500 1 1000 1 2000, etc.

3. The amount of shutter speed of the adjacent two stages is doubled, and we often say that there is a difference of one level. For example, 1 60 seconds is twice as much as 1 125 seconds, that is, 1 60 seconds is one level slower or one level lower than 1 125 seconds.

Introduction: The shutter speed is expressed in seconds or fractions of a second. Different camera manufacturers will have different shutter speed starting ranges, which is also important.

All SLR cameras have at least the following shutter speeds (maybe 500 more, and 1 1000 seconds). Some cameras use abbreviated speeds, such as marking 1 30 seconds as "30".

In order to distinguish between seconds and fractions of a second, these numbers are usually marked with different colors or their special markings on the body.

In general, each shutter speed is half the speed of the previous one, but twice the speed of the next one. For example, 1,125 seconds is half as long as 1,60 seconds and twice as long as 1,250 seconds. They are all one "stop" apart, and each gear is half or twice as long as it takes to get around.

From 1,125 seconds to 1,250 seconds, one gear was moved (halved time), by 1,500 seconds another gear was moved (halved again), and by 1,1000 seconds three gears were moved.

When the camera is set to a specific auto** mode, most cameras can achieve a "stepless" shutter speed. That is, the shutter speed can be determined by the electronics and set to any shutter speed, regardless of the fixed speed'Gear limitations. But even if the camera is set to this mode, the concepts of "halving" and "doubling" remain.

In recent years, most of the new cameras have shutter speeds that can be increased or decreased by 1 or 3 stops.

When you change the shutter speed, you also change the way motion physics is recorded on the negative. The faster the shutter speed, the clearer the image of the moving object on the negative, and conversely, the slower the shutter speed, the more blurred the moving object becomes.

Introduction to common SLR shutter speeds:The shutter is a device in front of the lens that blocks light from coming in, and it is a device that allows light to shine on the film for a period of time. In general, the larger the shutter time frame, the better.

The low second is suitable for shooting moving objects, and one camera emphasizes that the shutter speed can reach as fast as 1,16000 seconds, which can easily catch fast-moving targets. However, when you want to shoot the busy traffic at night, the shutter time will be extended, and the silk-like water flow effect in the common ** will also be shot with a slow shutter.

As for the b-shutter function that is common in DSLR cameras, although you can freely decide the length of time** and have more shooting flexibility, most consumer digital cameras cannot support it at present, and at most provide slower speed defaults such as 2 seconds, 8 seconds, and 16 seconds.

The shutter number is generally not commonly used, if you want to set it as the default shutter, then use the A gear or automatic transmission! Only these two stops are the default shutter counts. For example, the S and M stops can be set for shutter speed.

Usually shoot with shutter priority (A), you control the aperture and let the camera decide the shutter for itself. And there is no fixed shutter speed, the shutter has a safe speed, which is basically the reciprocal of the focal length, for example, the focal length is 50mm, then the safety shutter is 1 50, if it is lower than this speed, for example, 1 20, then the picture may be blurred due to shaking. The aperture value depends on your subject, if it is a landscape photo, it is best to be above f6, generally not more than f11, of course, it can also be f22, but it is not easy to control, not something that rookies such as me can master.

If it is a portrait, it is generally below f3, and it is easy to achieve background blur and highlight the person, but not every lens can achieve such a large aperture, so try to shoot a portrait time circle as large as possible, above the second stop of the maximum aperture of the lens.

First of all, change the drive mode to continuous shooting or high-speed continuous partner.

The shutter speed should be high, in order to compensate for the lack of **, you need to increase the ISO or open the aperture, but the depth of field of the large aperture will become smaller, since it is a high-speed action, it is easy to defocus, if the depth of field is not enough, you can't see it at once, and the small aperture may be able to make do.

Next is the autofocus mode, which needs to be adjusted to the intelligent servo autofocus (as the Canon camera is called), so that the focusing system constantly tracks the moving subject to focus and prevent it from falling out.

If the use of flash is allowed, high-speed sync can be used to freeze moving objects.

The above means should be used comprehensively, and the success rate of high-speed action is not high.

The shutter speed of high-speed continuous shooting is 5 beats per second.

The continuous shooting speed that a DSLR camera can achieve mainly depends on two aspects, one is the release frequency that the shutter component can achieve, such as 8 frames per second for 7D, which means that the shutter component can achieve a release frequency of 8 times per second, and the other is the processing speed that the camera's processor and cache can achieve, such as Canon's dual DIGIC processors, is to improve the processing speed, and it is for this reason that the camera's continuous shooting will have the maximum number of shots, and the number of continuous shots in RAW format is far less than that of JPG formatIt is also because the amount of information that needs to be processed for continuous shooting in RAW format is much larger than that of JPG

In real shooting, if the camera is set to continuous shooting, the camera defaults to the maximum continuous shooting speed, and some cameras can choose high-speed, low-speed continuous shooting or manually set the continuous shooting speed, which means that if your 7D is continuous shooting, then whether the shutter speed is 1 1000 seconds or 1 250 seconds, then the initial shooting speed is 8 frames per second. However, in practice, it is often impossible to reach this maximum continuous shooting speed, mainly due to the processor and cache, one situation is that when shooting continuously for a long time, such as continuous shooting in the actual shooting process, the fastest 8 shots in the first second, the second may only be 7 shots, and the third second may only be 6 shots. On the other hand, when shooting at a low shutter speed, such as a shutter speed of 1 to 20 seconds, it may not reach 8 frames per second in the first second, and because the slower the shutter speed, the longer the corresponding processing time, so the maximum continuous shooting speed cannot be achieved.

It seems to be a bit verbose, and I want to express my meaning clearly, and I want to talk about the issues to pay attention to.

It may be mainly in two aspects, one is to pay attention to the selection of appropriate focusing mode, especially when shooting sports pictures, high-speed continuous shooting can only play the best effect when combined with the correct focusing mode, and the second is that the fastest continuous shooting speed of the camera can last for a very limited time, so even when shooting sports pictures, you should also pay attention to timely continuous shooting, and should not keep pressing the shutter, you can try to shoot about three or five shots like continuous shooting, so as not to process because of long-term continuous shooting** It's been too long and I've missed out on the wonderful picture.
