It depends on theconditions that you are taking the photograph in. Also, the speeds incicated are usually the reciprocal so a sixtieth of a second or an eighth of a second.
Neither speed is any good if there is likely to be any movement - of the object or the camera.
The exact answer depends on the camera (or digital sensitivity), the film rating if using film, the sort of image you are looking for etc.

What travels at the speed of 300000 kilometres per second?
That is approximately the speed of light (c). In metric units it is exactly 299792458 meters per second (299792.458 kilometers per second). Even electrons in atoms travel at approximately the same speed (but always less than speed of light)
What goes from zero to one hundred and fifty in less than a second?
The speed of light.
How fast does a rock free fall in feet per second?
The speed keeps increasing. At any instant, the speed is 32.2 feet per second faster than it was 1 second earlier. That number is called the "acceleration of gravity".
Computers today make how many computations per second?
You are asking what the processing speed is and the answer varies for individual madels. The speed is measured in parts of a second (rather than by the second) and many newer computers are now built with two processors that work together to further increase the processing speed and capacity.
What does the phrase per second per second mean?
per second per second is taken with the context of how an object is changing its acceleration. An object accelerates by speeding up or slowing down. If an object speeds up, it could speed up at a rate of 5 meters per hour, let's say, every second. So after one second, its speed is 5 mph; after two seconds, its speed is 10 mph and so forth. If an object's speed is increasing at 5 meters a second, then its speed is 5 meters per second the first second; 10 meters per second the second second and so forth. We would say the object's acceleration is 10 meters per second / per second.AnswerIt has to do with speed,the time an object falls from a given height is calculated in seconds per second( it fell in less than a second)
How is the shutter speet measured?
Fractions of a second. 1/8 1/16 1/36 1/400 1/4000
What shutter speed should you use for landscape?
With a manual shutter speed for any stationary subject you should not go any slower than 1/60th of a second. That way you won't get a blurry image, but you still are letting in enough light into the sensor of your camera. Therefore for a landscape use the smallest 'f' stop possible provided the shutter speed is at least 1/60th second.
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 are the minimum values on the shutter speed scale in photography?
The minimum speed, i.e., the slowest the shutter will cycle, is B. The shutter will stay open for as long as the shutter release button is depressed. You can't get much slower than 'not moving'.
What is shuterspeed on a camera?
the shutter speed is how fast the shutter can go eg. an dslr has a faster shutter speed than a digital camera the shutter is a part on the camera that opens and closes when it opens it draws the light from the object focused on and places it on the lcd screen of film giving you your pic
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 is a exposure made when you take a picture?
Let's assume this is an film SLR with a dual curtain shutter since you didn't specify digital or not. When the shutter button is depressed, three things happen virtually at once. 1) the reflex mirror flips up to get out of the way of the light transmission. In so doing, it covers the focusing screen. 2) the lens "stops down" to the aperture chosen for the exposure by moving a series of metal blades (if it is to be less than fully open). 3) If the exposure time is equal to or longer than the flash synchronization speed, one curtain moves (usually horizontally), which uncovers the film opening for the set time. This curtain closes the flash circuit contacts and the flash fires while the film is completely uncovered if one is being used. Light transmits (not reflects) through the lens assembly to reach the film. The second shutter curtain closes, the mirror drops down and the aperture opens up again. If the shutter speed used is faster than the flash synchronization speed, the second curtain begins closing before the first has finished traveling. This has the effect of passing a slit across the film. The faster the shutter speed, the smaller the slit, so this design is capable of producing effective shutter speeds of 1/4000th of a second or less. When the shutter is cocked, the film advances and the shutter curtains travel back to their ready position. Some cameras use a vertical traveling metal shutter made up of a series of blades. They typically do not have a following curtain, and the distance of travel is 33% less than a horizontal moving shutter. This means their fastest shutter speed cannot usually be less than 1/1000th of a second. This is how the film is exposed to the light focused by the lens. Micron
What is an iris shutter in a camera?
Most companies call these shutters "leaf shutters." It's a shutter that's built into the camera lens. It has two advantages and three disadvantages over a focal plane shutter.The advantages are every shutter speed is a flash sync speed, and every lens contains a shutter of its own so if the shutter on your 80mm lens breaks you can mount your 150mm lens and finish the job. The disadvantages are slower shutter speeds than focal plane shutters will give (Hasselblad 500-series cameras go to 1/500 second and Hasselblad H-series go to 1/800; my Nikon F4 goes to 1/8000), having the shutter in the lens means you have to buy a new shutter with every lens and they are NOT cheap; and at the same shutter speed a focal plane shutter will allow more light to pass, so if you have a handheld meter you have to adjust your exposure to accommodate this.
How do you set shutter speed for minutes or hours?
Most cameras don't have a dedicated shutter speed longer than thirty seconds. If you wish to take exposures longer than that, use the bulb function ('B' on most cameras). Bulb allows the shutter to stay open as long as the shutter button is held down. Get a locking cable release, switch camera to bulb, and you can take any length exposure you want.
What is exposure mainly controlled by?
For the most part ISO controls how much light reaches the sensor but so does Shutter speed, A shot with settings of ISO 100 with a shutter speed 1/500th of a second if shot in bright direct sunlight would give a reasonable picture. If you can not drop your ISO lower that 100 then you increase or decrease your shutter speed depending on how much light there is, in this case the the higher the shutter speed the less exposure meaning the darker the photo, the slower the shutter speed for example, anything starting to get below 70 fps (frames per second) requires that your arms have to be fairly steady or u get blur, anything at 1/20th of a second going on to 1 or 2 second with the shutter open require a stand and may require darkening filters, it all depends on what your camera is capable of, and what you want to bring about as an effect in your photo. Some Cameras will allow you to do Lower than 100 ISO but thats the industry standard for a normal picture. When you start to get more in depth F settings come into play, as this would widen or narrow the focal field, again letting more or less light to the sensor

How well do wood shutter blinds regulate room temperature and light?
Wood shutter blinds regulate room temperature better than blinds build of metal. There is almost no difference in light regulation.
