What happens when you open up the lens aperture but do not change the shutter speed?

You will increase the film exposure compared to what the on board light meter is suggesting. This is known as over exposure, but that is a relative term. "Over exposure" is not necessarily a bad thing.

What happens when you close down the lens decrease the lens opening and do not change the shutter speed?
Underexposure without a change of lighting corresponding to your aperture.
What is aperture priority in photography?
Aperture priority lets you set the aperture you want and the camera sets the shutter speed for you. You use it when you want to control depth of field. Shutter priority lets you set the shutter speed you want and the camera sets the aperture for you. You use it when you want to control how motion is rendered in the photograph. Program mode sets both shutter speed and aperture for you. Use it when you are not concerned with aperture or shutter speed control.
If you are changing the shutter speed why is the depth of field being affected?
Usually, one would change the aperture to compensate for the change in shutter speed in order to keep the level of exposure the same. Changing the aperture affects the depth of field.
What is meant by Aperture priority?
Aperture Priority has the camera set the shutter speed for you allowing you to set the aperture and it will set what shutter speed it thinks is best for your current light situation.
What are you setting when you set the shutter speed?
The amount of time that the shutter remains open - allowing light to pass through it to form the image. Generally - a lower shutter speed would be combined with a smaller aperture and a higher shutter speed with a larger aperture to correctly expose the image.
What do the shutter speed and aperture sizes both control?
light
Why is shutter speed used?
The shutter speed setting controls the picture exposure, or how dark or bright the picture will be. Wikipedia has some very good information on shutter speed and aperture.
Will changing the camera's f-stop will not change the camera's shutter speed?
If the camera is in an automatic or programmed mode, yes, the shutter speed will be changed by the on-board metering system if the aperture is changed. If it's in a manual mode, no.
What is aperture priority of digital camera?
Exposure, in digital or film photography, is determined by aperture and shutter speed. On a manual camera, the user selects both values.On an automatic camera, there are four possibilities:Manual mode. User selects both aperture and shutter speed.Shutter priority. User picks the shutter speed and the camera adjusts the aperture to ensure proper exposure.Aperture priority. User picks the aperture and the camera adjusts the shutter speed to ensure proper exposure.Program mode. The camera selects both values.
How do aperture and shutter speed work together to achieve proper exposure in a photograph?
Well when the aperture is wide enough and shutter speed is not fast enough then there will be enough amount of light for the photo to be taken and looking good enough.
How exposure system works and affect the image?
Exposure is the combination of aperture and shutter speed. Aperture (measured in f-stops) determines the amount of light that will enter your camera. Shutter speed (measured in seconds) determines the amount of time that the shutter will stay open to allow light to enter.
What two variables on a camera control the exposure of the film?
shutter speed and lens aperture
