Question: Shutter Speed Question!?
I just got the D40 today and I was wondering why very fast shutter speeds make the picture black!? Like 1/2000th sec!. Thanks!.Www@QuestionHome@Com


Best Answer - Chosen by Asker:
because it is to fast for the apature setting and iso and the available light!.
read the little book that came with the camera!. it has loads of information in it!.Www@QuestionHome@Com

Because they don't let in enough light to make a proper exposure!.

Sounds like you need to pick up some knowledge about how exposure works!. Here's a place to start:

It'll save you hours of wondering why your pictures look like they do!.

With that fast of shutter speed you will need a very bright light sorce and/or open your f stop to 4!.0 or bigger which is a lower number, don't go to f8, f11 or more go the other way!.
You should see a big differenceWww@QuestionHome@Com

you need to study "exposure", 2000th is fine if the light is strong enough and you know what your doing!.!.!.!.!.

try this link: http://en!.wikipedia!.org/wiki/Exposure_(p!.!.!.

or ask : "what is exposure"

Well I have to give you credit for at least taking the thing out of AUTO and experimenting! But as the others have said, you need training and knowledge of exposure principles!.

buy 'understanding exposure' it will give you loads of information and explain all that shutter speed stuff ;)Www@QuestionHome@Com

Because you likely do not have an aperture large enough to support that shutter speed!. You need to learn the very basic fundamentals of exposure to understand!.

There are three main factors that control exposure!.

The aperture controls how much light hits the image sensor, and is represented by the f/number!. The aperture is like the iris of your eye, the larger the opening the more light can be gathered by the eye!. When it is dark, your iris is open very wide to allow you to see, and the opposite when it is very bright!. With a camera lens, the larger the opening or aperture, the smaller the corresponding f/number, i!.e!., f/2!.8 is a larger aperture than f/16!. The aperture adjustment is set in what we call stops, one stop smaller from another effectively halves the amount of light that is allowed to enter the camera than was possible before!. For example, f/4 is one stop smaller than f/2!.8, and subsequently reduces the amount of light emitted by the lens by half, f/5!.6 reducing the light by half from f/4, and so on!. Depth, or how much of a frame is in focus is also controlled by the aperture!. The larger the aperture, the less of a frame will be in focus due to a shallower depth of field, rendering everything but what is being focused on out of focus!. The smaller the aperture, the more will be in focus from the foreground to the background of a frame!. This is used to define the subject of a frame!. In portraiture, a shallow DoF is desired to isolate the subject from it's background by blurring everything but the subject itself, and is thought of as being an attractive aesthetic!. But the opposite is desired with landscape photography, where a broad DoF is desired to keep everything within frame sharp and in focus!. Among those factors, the diameter of the aperture governs how fast the shutter mush be!.

The shutter controls how long the light hits the image sensor, and is adjusted in stops as well, and is set in fractions of a second using the principle of halving the amount of time the shutter stays open!. For example, a change from 1/15 to 1/30 reduces the time the shutter stays open by half!. The shutter also controls motion within the frame!. A fast shutter speed is used to freeze motion!. For example, a sporting event is often photographed using a fast enough shutter speed to freeze motion so we can see things like expression and definition of the athlete, sort of like the frozen stature of the figure used in the heisman trophy!. But, when we want to show the effect of time on a frame, like movement from cars, people around a stationary object, or the smooth frothy effect of moving water a slower shutter speed is needed!. The longer the shutter stays open, the more exaggerated motion becomes!. Things that move will blur within the frame!. What can be done with both the aperture and the shutter speed are controlled by how sensitive the image sensor is to light!.

ISO refers to the sensitivity of the image sensor to light!. Much like in film, there are increments of values used to represent ISO that are known as, yep you guessed it, stops!. One stop higher from another effectively increases its sensitivity by double!. ISO 400 is twice as sensitive as 200, 800 twice as sensitive as 400 and so on!. The ISO determines how fast you can set your shutter speed for the desired aperture and is how you can maintain depth without effecting the shutter speed!. As with film, the higher the ISO becomes, the more artifacts will become visible and is generally known as noise!. When the gain is increased, the inherent noise becomes higher and more visible as luminance and chroma noise!. But, with an increase in ISO, for example from 100 to 200, double the shutter speed can be attained without changing the aperture value!.

These three things work in unison to produce the proper exposure for any given frame which is measured by the camera's light meter!. At 1/2000 of a second, with a black frame, your shutter speed was way too fast for the aperture!. Unless outside in direct noon sunlight, with a wide aperture, you will likely never use 1/2000 as a practical shutter speed!.

I recommend you read a book titled "Understanding Exposure" by Bryan Peterson!.

Much of what I have written in this answer can be better explained in more depth by reading that book!. In my opinion, everyone who buys an SLR type digital camera should own that book and should learn the basics of exposure and photographic composition, even if you don't intend on being the next Ansel Adams!. At the very least, it's pretty interesting stuff to learn!. I hope this answer helps your understanding and congrats on your new camera, it's a good one!.Www@QuestionHome@Com
