Shutter speed is how long the shutter is open allowing light to hit the film/ imaging sensor.

The longer the shutter is open, the more motion or blur you will see. An example of a long shutter speed would be a car that is blurry because it moved during the exposure.

The faster shutter speed will stop something moving and make the subject appear sharp (as long as it's focused right). Think bullet going through a balloon, that is a very fast shutter speed.

Similar to aperture, the shutter speeds either doubles of half the amount of time the shutter is open. A shutter speed of 1/125th of a second is open twice as long as a 1/250th of a second. Conversely, a shutter speed of 1 second is open half as long as it would be at 2 seconds. This is pretty easy stuff, huh?


(I better be careful, you may just understand how I make some of my photos and not be as easily impressed.) :lol: Just kidding, I am happy to help those of you that are genuinely interested in learning photography. :goodjob:


Questions?

nice. this one i understand a bit more. it's combining aperature and shutter speed together that makes me cornfused.

Nice demo pics! Would you say 1/350th is generally good for getting good detail on a baseball bat or a tennis racket in action?

Aperture and Shutter speed are used together to limit the amount of light reaching the film/sensor. Aperture is how much light is let through the lens, and shutter speed is how long the light is allowed to hit the film/sensor. :D

Cool, I think I know the next tutorial. Aperture is how big the opening that lets in light is. Small numbers = big opening and big numbers = little opening. The smaller the opening the bigger the depth of field. Did you already give that lesson?

Great stuff as always. Wish I had a good digital.

I didn't see the aperture thread when I posted that. I wasn't trying to be sarcastic or to kill this thread. I just got excited that I understand this stuff.

You killed this thread? :confused: Where was I? :lol:


I am very happy that you understand Dave! :goodjob:

the first time I put it all together, shutter speed, aperture, focal length, and ISO, I realized it isn't really that hard to understand. It just takes someone to put it in a way that makes sense to others.


Wait until I talk about reciprocity failure and hyperfocal distance! :roflmao: (They are both easy too!) ;)
