Why do I get darker photos at high shutter speeds?

Yesterday I was asked by a person regarding why he got darker photos every time he  increased the shutter speed.

The answer is simple.
Shutter speed controls the entry of light into your camera. High shutter speed means the camera's shutter is open for a smaller period of time and thereby restricting the amount of light entering the camera.




These photos were taken at  f/5.6, ISO 100 at the following Shutter Speeds 

                                                            See the difference?
                                                             


How fast is fast enough?
1)Most digital SLRs offer a max shutter speed of 1/4000, while some high end cameras offer a max shutter speed of 1/8000. Using the camera's max shutter speed will usually produce darker photos,

2) 1/125 to 1/250 are your safest options to shoot at. These shutter speeds are fast enough to freeze a moving subject like birds and cars.

3)If you wish to increase the shutter speed, it is advisable to increase the ISO or use a flash.

4)Fast shutter speeds  reduce the blur caused by camera  shake.


Whats the solution?
1)You can shift your camera dial to auto or program mode.
2)Shift your camera dial to Shutter Priority and use "Auto ISO".

Use the Shutter Priority Mode

3) If you want to use the Manual mode and still shoot at a fast shutter speed, increase the ISO speed and shoot with the aperture wide open (at a lower f-number).
4)Use the built-in or an external flash.

When to use high Shutter speed?
1)When you are trying to freeze a moving subject.
2)When shooting Sports and Wildlife.
3)When you are using a telephoto lens.
4)When you are shooting in bright outdoor conditions.
5) When you have read this article and know what is to be done, he he.
