Get The Most Out Of Your Camera Part 2



Get the​ Most Out of​ Your Camera .​
(Part 2).
In part 1 of: Get the​ most out of​ your camera, we looked at​ how to​ use the​ aperture and​ the​ creative uses of​ depth-of-field .​
In this part we’ll look at​ how to​ use the​ shutter button on your camera and​ how both the​ shutter and​ the​ aperture control exposure.
The shutter is​ a​ mechanical device that controls the​ length of​ time that light is​ allowed to​ act on the​ film.
Most standard cameras allow us to​ use a​ range between 16 second and​ 1/1000 second .​
You might be wondering, why anyone would use a​ long shutter time of​ 16 seconds: I’ve used this and​ even longer shutter times when taken lowlight landscape images .​
I​ would always advise the​ use of​ a​ tripod with these long exposures time to​ avoid blur images .​
Using a​ shutter speed of​ 1/125 second should safely avoid overall blur due to​ camera movement if​ you hold the​ camera by hand .​
Any longer shutter time should require a​ tripod.
Each time you open the​ shutter by one, we double the​ light, when we close down the​ light by one we half the​ light .​
Open the​ shutter at​ 1 second allows twice the​ light as​ that of​ a​ ½ second.
The shutter can also be used creatively when taking landscape images or​ sport images .​
If you want to​ add motion to​ your image a​ slow shutter speed can give an​ image an​ extra bit of​ sway .​
No more so than taking images of​ streams .​
Using a​ slow shutter speed when photographing water will cause the​ water to​ blur, resulting with the​ image expressing motion .​
By contrast, a​ fast shutter speed of​ 1/250 would be used in​ shooting wildlife or​ where the​ subject that you’re shooting needs to​ be still and​ sharp .​
Most wildlife photographers would use a​ fast shutter speed .​
By using the​ shutter and​ aperture together we control exposure .​
Both allow light to​ enter the​ camera: the​ shutter by time and​ the​ aperture by the​ size of​ the​ hole in​ the​ lens .​
For example: you’re shooting a​ landscape scene; you get an​ exposure reading at​ f/11 at​ ¼ second .​
You know that by using f/11 that the​ entire image wont be sharp .​
You want to​ shoot at​ f/22, which is​ four times less light than f/11 .​
You need to​ quadruple the​ light through time; each time you open the​ shutter by one you double the​ light, so open it​ by two stops and​ your exposure time will be 1 second .​
Your final exposure should read f/22 at​ 1 second.
At the​ best of​ times, calculating the​ correct exposure can be a​ difficult task, but with a​ few simple tips our images can produce eye-catching colours that we see all around us every day.
