    If you are using a 50 mm lens, the slowest shutter speed you can use without a blur is _____ of a second, based on the reciprocal rule.

    • A.

      1/250

    • B.

      1/125

    • C.

      1/50

    • D.

      1/500

    Correct Answer
    C. 1/50
    Explanation
    According to the reciprocal rule in photography, the slowest shutter speed that can be used without causing blur when using a 50 mm lens is 1/50 of a second. This is because the reciprocal rule states that the shutter speed should be equal to or faster than the focal length of the lens to avoid blur caused by camera shake. In this case, since the focal length is 50 mm, the slowest shutter speed would be 1/50 of a second.

    Depressing the shutter release half way adjusts the focus and _____.

    • A.

      Exposure

    • B.

      Camera mode

    • C.

      Focal plane

    • D.

      Shutter speed

    Correct Answer
    A. Exposure
    Explanation
    Depressing the shutter release halfway adjusts the focus and exposure. When the shutter release button is pressed halfway, the camera's autofocus system is activated, allowing it to adjust the focus on the subject. At the same time, the camera's light metering system measures the available light and determines the appropriate exposure settings for the shot. This includes adjusting the aperture, shutter speed, and ISO to achieve a well-exposed image. Therefore, depressing the shutter release halfway not only ensures a sharp focus but also sets the correct exposure for the photograph.

    • D.

      Depth of field button

    Correct Answer
    B. View finder
    Explanation
    The photographer uses the viewfinder to see what will be photographed, read settings, and adjust focus. The viewfinder is a small window on the camera that allows the photographer to look through and see the subject before capturing the image. It helps in framing the shot, ensuring that the desired elements are included in the frame. Additionally, the viewfinder provides information about the camera settings, such as aperture, shutter speed, and ISO, allowing the photographer to make adjustments as necessary.

    When a SLR camera takes a picture, the _____ flips up automatically.

    • A.

      Focal plane

    • B.

      Aperture

    • C.

      Shutter

    • D.

      Mirror

    Correct Answer
    D. Mirror
    Explanation
    When a SLR camera takes a picture, the mirror flips up automatically. This is because SLR cameras use a mirror mechanism to reflect the light coming through the lens onto the viewfinder, allowing the photographer to see exactly what will be captured in the image. However, when the picture is taken, the mirror needs to move out of the way to expose the camera's image sensor to the incoming light, hence it flips up automatically.

    • C.

      Orange

    • D.

      Cyan

    Correct Answer
    A. Green
    Explanation
    The individual sensors in a CCD (charge-coupled device) are filtered for red, blue, or green. This is because these three colors are the primary colors of light and are used to create a wide range of colors in digital imaging. By filtering the sensors for these specific colors, the CCD is able to capture and process accurate color information in images.

    In general, the _____ number of pixels, the finer the details the camera can potentially record.

    • A.

      Smaller

    • B.

      Larger

    Correct Answer
    B. Larger
    Explanation
    The larger the number of pixels, the finer the details the camera can potentially record. This is because a larger number of pixels means that there are more individual dots of color that make up the image. With more pixels, the camera can capture more information and provide a higher level of detail in the resulting image.
