If you've ever tried to take pictures of your children while they run on, what they probably experienced. Wait "until they are perfectly positioned in the frame, press the shutter button, and ends with a shot from the back of the head to leave the pictures. That's shutter lag, and most digital cameras have a way or ' other.
What causes the shutter speed?
E 'caused by a couple of things, but the main one has to do with your digital cameratechnology itself. The image capture chip inside the camera is actually produces a video image in continuous motion. This is what you see on the camera screen or viewfinder. When you press the shutter button, you are actually a frame "freeze" the video recording.
Therefore, the camera manual to refer to the picture taking as a process of "image capture". Whatever one calls it, is a fact that it is more of treatment, and therefore can take alonger period. digital cameras, all digital devices, more powerful with each new generation, so you should wait for me a new camera shutter delay is less than an older, but there is no guarantee of this.
What can you do?
There are three possible approaches to the problem of shutter lag. You can remove, reduce or expect. Of course, that a fourth option may be ignored, and if anything onlytaking pictures of relatively static scenes, will probably never even seen. And 'only when you try to capture a moment or a moving subject Vliet believed to be a problem.
Eliminate shutter lag.
There is only one foolproof way to do this is using a type of semi-professional or professional DSLR camera. These cameras are an "old style" mechanical shutter, which has no delay. But because of this, you get ato see the back of the camera, so you must use the eye as you did with a camera.
Minimize the shutter.
The way in which digital cameras, the images are not the only reason for the delay, some of the settings of the camera has a profound influence on the amount of delay. The culprit is far worse than an "anti-red eye flash option. You will be burning in the lightning several built before taking the photograph.
Friendof mine once had a lot of pictures at a party with his new digital camera. He thought that his camera was broken, because all the pictures, you could cut the head of all. It 'clear that the problem was when I saw him take a picture.
Basically, he was doing all right, except that the anti-aging red eyes of fire all the flashes, and only the latter that actually the image. From then shot himself, would leadcamera mode and look for the next group for a photo. Then cut the head. When he learned to wait for the last flame, his picture of the composition of improved incredibly.
A small, but still sometimes considerably delayed by a camera, which is caused to set exposure and focus for the image. Both these things are done with the engines of small moving parts of the lens, and will always be a certain amount of time.
To stopoccurred in two ways. One is to set exposure and focus based on the camera. Not all cameras will allow you to do it and believe it is not all that many people do not want to "go manual" in every case but all is not lost. It is usually possible to minimize the delay of departure, while all controls in a completely automatic.
The shutter double switch
Take your camera in a quiet room and slowly press the shutter button. Before you reach the buttonend of his journey, you have heard (and maybe feel) the engines of the lens is turned on. This is your camera sets its exposure and focus before the image. Only when the button when at the end of his trip was the picture that really counts.
Art (or technology) is to press the button only halfway down and hold it there. He's got things were too slow in advance, pressing the button the rest of the path will have the image with the absoluterelaxation time minimum. This technique can also be used to pre-focus. "For example, if you want to focus on something on the edge of the frame. We must concentrate on it, press the shutter button halfway again the frame when you press the button shutter and take a right into the picture.
Anticipating shooting.
As one might expect, it will take some 'time, effort and practice on your part, but it can be the difference between taking a picture you want to hang on the wall, and what you dowill soon be removed.
To find out what actually shoot camera, you can try: Get a scene with a strong vertical line, like a lamp or end of a wall, etc. Pan the camera slowly through about 50 degrees, then line up the edge of the frame. Do this a few times at a constant speed. Can be useful if you count slowly panning.
On one move, press the shutter button as soon as the tag line appears on the edge of your search –but keep the pan is important. The cursor should be at the center of the frame. Up to that point in the middle depends on the amount of delay. Repeat this a few times and you begin to create a sense of magnitude of the delay of the camera to get.
Now try to anticipate the moment. Camera Pan on the other hand, try to press the button when the cursor to get to the point where it was the image you have and keep panning. This time the cursor is on the vergethe frame when the photo was taken. If it is then you have a good sense of how long your camera's shutter has been improved.
Keeping spontaneity
Relaxation time is the most annoying when you try to get honest, spontaneous photographs. The moment the "perfect" is easily lost if you wait for the camera. One technique you can try is to undertake the subject is facing the camera. Ask them to turn and face the cameraWhen you call their name. The trick is to press the shutter button when the name of her talk.
If you continue to face the camera when the picture was taken, but then ask them not to look so far away from the camera at first. Most people's facial expressions are more natural when they do something at that time (including rotation) instead of just looking forward to a camera for their picture to be taken.
If all else fails – cheat!
EvenIf you have a feel for the delay in the camera, it will still be difficult to capture the perfect moment, but there is one last thing you can try. It depends on your camera with a multi-exposure "approach. But many of them. This will be several images in succession as quickly as possible to participate. So the technique is simple for many, many pictures.
This is a perfectly legitimate technique that is used by all professionals of the time in a reportsituations in the movement. It's just really say if you take enough pictures, so one of them is destined to come out "right." If no images, then simply are not enough outlets.
It used to be one of the things that separates the amateur photographer by profession, because the cost of the film would have prevented a person who is not paid for the work. Of course, in the digital world has changed everything. Almost anyone can guarantee a good imagetheir camera has some shutter speed or not.
