Lesson 3 the stability of hand-held shooting

Hello everyone students, teachers lazy for a week, finally started to spur own efforts, so today to talk about the stability of handheld shooting.

In previous work, in order to seek stability, the teacher had asked students to use a tripod to shoot. But in any case not suitable for a tripod, in fact, taken many actions are done using hand-held shooting, this time, the stability of handheld shooting is an issue to note before shooting.

Clear a picture or not, is often being used to review the results of an important reference point shooting, most people would think that a "successful" photo, must be clear (that is not vague ) screen. So how can shoot a "clear" pictures, is for beginners to pay attention to an issue.

The stability of handheld shooting, depending on the shooting shutter speed used, and of course the length of your lens focal length shooting habits and adopt good posture is very important. A few days, the teacher will write another article on the shooting posture habits and suggestions to the students, now let's take a look at today's issue: stability.

What we can shoot a stable and clear floor under the photo? In general, there is a simple formula can be used as a reference when students take the value, that is:

Shutter = 1 / lens focal length

This means that you are using will be taken as a lens focal length is the denominator, it becomes a security (that is, you can shoot clear photos) of the shutter time. Give you an example, if we use a standard 50mm lens to shoot, as long as the shutter not less than 1 / 50 seconds (if not the shutter, however, that as 1 / 60 seconds,), we can shoot a clear picture. If you are using a long lens to 200mm, then the shutter can not be less than 1 / 200 sec (also not the shutter, then 1 / 250 second bar).

This way we can see that longer the focal length of the lens, we can use the shutter time will be shortened, and hand-held wide-angle lens to shoot but can use 1 / 30 second shutter. But the above only as a reference value, in general, everyone can master the shooting stability are not the same, and some people can shoot a very slow rate that it is very clear pictures, and some people even took the wide-angle lens with a short shutter, but still gained a lot of shaking blurred photos (do not do not believe the teacher read to take wide-angle lens with 1 / 60 second film will be shot clear of people).

The teacher can not tell you how far the shutter speed can grasp, we do not need this class for testing photo, because today you can use 1 / 30 seconds to shoot a very clear picture, but they might not because of physical, Used 1 / 125 second of the film instability. You just noticed your using the lens focal length, and shutter speed is not too far off with a can, and in fact many students can also try to see the stability of their own about where to go. Known as the teacher's teacher can take the guns at a young age (that is just the kind of great big long-only lens) with handheld shooting beautiful photographs, but now support artillery support for a long time, often guilty of rheumatoid wrist ....。

In general we took portrait photographs, in order to have more flexibility with handheld shooting, and they tend to shoot portraits of the students to practice your own arm, let it satisfactory. As regards the application of the landscape group of students or use a tripod to shoot, no matter how strong the arm would not be stable than a tripod, to the United States and the United States landscape, or more than carry out a tripod.
