What is Shutter Speed?

Question

Do digital cameras have it?

Answer 1

Hey Joy,

This is how long the shutter stays open to let light in. If it is quick, that is good for high light, and/or fast movement. Digital cameras - do have this feature in the more expensive ones. Most Digital cameras come with Flash or not. To take a night shot, you need to leave the camera still, and the shutter open longer, some digital cameras allow for this type of adjustment. You have to do your homework on cameras to know for sure.

Joy, the shutter speed refers to the length of time that a lens' opening (aperture) is open to let in the REFLECTED light from the subject(s) you're photographing.

A camera is a lightproof box. No light gets in. The part of the camera that lets reflected light into a camera is the lens.

Aperture is the opening of the lens. How big or small the aperture (opening) is often referred to in "f" numbers. The "f" stands for "factor," because the size is measured by a mathematical equation. For example, if I have a lens that is 50mm in focal size (focal size refers to the distance between the center of the outer lens to the plane where the film or sensor lies), and I say, "f/2," what I am referring to is 1/2 the size of the focal length; I am saying that the aperture is 25mm in size, which is 1/2 of the focal length of the lens. Likewise, if I say, "f/3" I am referring to a size that is 1/3 of the focal length of the lens; and, if I say, "f/4," I am referring to an opening that is equal to 1/4th the focal length of the lens.

Insofar as shutter speed, it refers to how long the lens' opening will remain open to allow the reflected light from the environment or the subject you've focused on to reach the film (if using a film camera) or the sensor (if using a digital camera).

Good luck and best wishes.

Hello Joyfulness~

I'm not positive, but I am pretty sure that the shutter speed is either the amount of time the shutter lets light in while taking the photograph, or it is how long it takes to focus, but I'm pretty sure it's the first one. I want to go to Brooks College of Photography when I get older, so I hope the answer I am giving you is correct!

P.S- I have a Red Exlim Digital Camera, and I have the Shutter Speed Feature, but I don't think this feature is on all cameras, hence the the "feature" part of it. :)

Answer 4

The shutter is the mechanism that opens to let light into the camera for the exposure of light to the medium in use

The shutter speed is the amount of time that the shutter is allowed to stay open FOR this exposure to happen

All cameras have a shutter and therefore a shutter speed----
however--- a lot of cameras these days are totally automatic in their settings and so you don't always have a manual setting available to set these speeds manually !!!

Answer 5

Shutter speed if the amount of time the aperture is open during picture taking. This is important with film because there are different film speeds. They make take longer or shorter exposure time to affect a good picture.

Answer 6

THE SHUTTER SPEED MEASURES THE AMOUNT OF TIME THE LIGHT REMAINS ON THE FILM.

Answer 7

how much or long light is allowed in.
