shutter speed Flashcards
What does shutter speed do?
1) changing brightness. Higher shutter speed allows light for a short interval of time and due to lack of light this causes darker image while lower shutter speed allows light for a long interval of time thus more lights thus causing the image to be brighter.
2) Gives us motion blur. Higher shutter speed takes in light from a small interval thus the target in image looks frozen while lower shutter speed takes in light for a longer period which means if the target moves within the period those movement’s light is also captured (motion blur).
we want to capture something (Ex. bird) that is moving too fast in a bright environment, explain how does the shutter speed affects the image.
If we use high shutter speed, we can get the image of the bird frozen in time, since our shutter speed is faster than then motion of the bird. Generally the image would be darker but the environment is bright so our image would be bright and sharp.
If we use slower shutter speed, our image of bird would have a motion blur since the bird speed is faster than our shutter speed. It would feel as if we capture the flying motion of the bird. But the since the environment is already bright, having lower shutter speed will over expose our target making the photo too bright.
How does image brightness change with shutter speed?
as the shutter speed decreases the image brightness increases.
common scenarios and their shutter speed
People who pose and stay relatively still = 1/125
Moving people = 1/200-1/800
Landscape: blurring water movement = 1-10 seconds (depending on the effect you want)
Perched birds = 1/320 (they still move a little)
Birds in flight =1/2000 ( to freeze motion)
Macro photography =1/320
Flash photography= 1/200 (the flash sync speed, lower if you want to drag the shutter)
Astrophotography= 10-25 seconds
What do we need to be aware of when taking shots in slower shutter speeds?
We must not shake the camera or else our image would have unwanted motion blur. So the idea is to use camera stand(tripods). Some cameras have built in stabilization feature.
What is a Slow Shutter Speed?
A long shutter speed is typically around 1 second and longer. In comparison, a slow shutter speed can refer to a fraction of a second, such as 1/2 or 1/4.
What is a Fast Shutter Speed?
A fast shutter speed is often referred to as the shutter speed that is fast enough to freeze action. Typically, photographers refer to small fractions of a second, such as 1/250th of a second or faster when talking about fast shutter speed.
How Do I Find My Shutter Speed?
Shutter speed is often displayed on your camera’s top or rear LCD as a number or fraction. If you half-press the shutter release (this is the button where we press to take picture), then move your camera towards a brighter area, the number that changes is typically your shutter speed.
Which Shutter Speed is the Slowest?
Depending on your camera, the slowest shutter speed that is allowed to use without using a remote shutter release is typically 30 seconds.
What is the Fastest Shutter Speed I can Use on My Camera?
That depends on the camera’s capabilities. Most DSLR and mirrorless cameras can shoot as fast as 1/4000 of a second using the mechanical shutter. Some of the more advanced cameras can shoot as fast as 1/8000 of a second with mechanical shutters, and even faster when using electronic shutters.
How is Shutter Speed Written?
Shutter speed is always written in seconds or a fraction of a second. For example, a 1-second shutter speed is typically displayed as a single number with a quote sign or a letter “s” at the end of it, such as 1″ or 1s. Whereas a fraction of a second such as 1/250 is typically displayed as 1/250 or simply 250 on most cameras.
What is the Best Shutter Speed?
There is no such thing, as it really depends on what you are trying to achieve.
