In a mechanical shutter it is the time that it takes for the mechanical components to mesh and begin the movement of the shutter blades. These components must also build up the forces necessary to move against the springs that hold the blades in the closed position. This build up of forces takes some finite amount of time to overcome, hence a lag time. Then, depending on mass of the shutter blades there is a finite time it takes for the blades to move to the open position. This is due to inertia. (Inertia is the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force.) In an electro-mechanical shutter additional lag times are provided by the inductance of the actuating mechanisms, (usually some electro-magnetic actuator). In these cases the time it takes for the actuator to build up the energy necessary to be able to overcome the "at rest" forces causes additional lag. Shutter lag is a property that shutter manufacturers work very hard to reduce to a minimum required duration.

******************

While technically correct, shutter lag in a modern non-digital SLR is virtually undetectable. The questioner was probably referring to the lag time of a non-SLR digital camera, which as most people have observed, can be a pain in the butt. The answer in that respect is that the lag is due to the time it takes the image to be converted to digital information. High priced digital SLRs have much less lag as their processing time is much shorter. The trade-off is the dent it puts in your wallet.

How do you take a picture with a camera?

All cameras are equipped with a "Shutter Button", this button opens the shutter release light onto the image canvas, then automatically shuts the shutter. Then you have a picture.


What is shutter speed in photography?

Shutter speed is how fast your shutter opens and closes to take a picture on your camera. Shutter speed also has a lot to do with exposure. The higher the shutter speed (1/2000 example) the less light.


What is the shutter speed of the polaroid i1036?

All cameras have multiple shutter speeds and depending the mode your camera is (Manual, Auto, etc...) the camera will choose what shutter speed it thinks will be appropriate for the picture. And most cameras will also not tell you the shutter speed you used, while some will.


2 types of camera shutters?

There are more than two, for sure. I know of the focal plane shutter (a pair of horizontally or vertically traveling blinds near the film plane), the leaf shutter (usually 1 to 3 blades contained within the lens that pivot to uncover the opening) and the diaphragm shutter (3 to 5 blades that pivot in such a way as to create a roughly circular opening much the same way as the aperture blades in a SLR lens). I believe the term "central shutter" is used to describe the position of what is usually a diaphragm shutter as opposed to being a type on it's own. The earliest and simplest shutter was, in fact, the lens cap itself. The two basic types of shutters are the Focal plane shutter and the Leaf shutter.


When could bracketing by shutter speed cause a problem?

When the higher or lower shutter speed either renders motion in an unacceptable way (depending on the subject matter) or the lower shutter speed is too slow for hand-holding the camera.

Is there a measurement for shutter lag on digital cameras?

There is no measurement for shutter lag, unfortunately, on digital cameras.


What does it mean to have shutter lag?

Shutter lag is the time from when the shutter is triggered (pushing the shutter button) until the time the image is recorded. In professional cameras the shutter lag is far less than consumer cameras. Some professional cameras will take 6 to 8 frames per second when triggered by hand. Consumer cameras vary from about a tenth of a second to 2 seconds of shutter lag.


How do you make your digital camera faster?

If you mean, how can you reduce the shutter lag, you can speed things up by prefocusing (hold the button down halfway) before you have to take the picture. Read your manual.

How do you reduce lag in HON?

Turn the settings down as far as you can and in interface turn off the option of the outline around selected things because that also causes some lag on a poor computer.

Is there a digital camera that will take pictures the precise or near enough moment you press the button?

I believe you are referring to Shutter Lag. It's the amount of time you wait between pressing the button and the camera actually taking the photo.Generally speaking, more expensive cameras have smaller Shutter Lag times. DSLRs are almost instant, but even they have a little lag time.In small point-and-shoot cameras, Sony tends to be a little quicker than most.Important Tip:Automatic cameras do several steps before they actual take the shot. They 1) focus, 2) calculate the exposure, and 3) take the shot.If you press the button down half way and hold it there, the camera will complete steps 1 and 2 and wait for you to press the button all the way down to do step 3.Pre-focusing before your shot, by holding the button down halfway, will reduce your shutter lag time.This means you have to think ahead and be ready for the shot before it happens. This is true for any camera, even the big DSLRs.

How do you change your JVC GR-D770U camera to night mode so it doesnt have strobing?

There is no other way because making the subject lighter causes for the shutter to be open longer. This is what causes the strobing.


What are disadvantages of using a camera?

Shutter lag is the most commonly cited problem with digital cameras, because of the time it takes for auto focusing and the activation of the picture capture mechanism, often in situations where timing is important like sports events, the time between pressing the shutter button and the actual time the camera records the image can mean the difference between getting or losing the shot.
