Learners examine how the image sensor replaces chemical film processing, then connect aperture size and shutter duration to exposure outcomes such as overexposure, underexposure, and motion blur.

Most cameras produced today are digital, largely replacing those that capture images on photographic film. While there are still dedicated digital cameras, many more cameras are now incorporated into mobile devices like smartphones, which can, among many other purposes, use their cameras to initiate live video-telephony and directly edit and upload images to others. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higherquality photographs.  \nDigital and digital movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the image, just as with film but the image pickup device is electronic rather than chemical. A computer then breaks this electronic information down into digital data.  \nSource: wikipedia  \nDOCUMENT 2: Professional digital camera  \nSource: wikipedia  \nHasselblad 503CW with Ixpress V96C digital back, an example of a professional digital camera system  \n◼ Vocabulary:  \nList the main components of a digital camera:  \n_________________________________________________________________________________________________  \n_________________________________________________________________________________________________  \n______________________________________________________________ ___________________________________  \nACTIVITY 2: digital camera resolution  \nDOCUMENT 3: resolution  \nThe amount of detail that the camera can capture is called the resolution, and it is measured in pixels. The more pixels a camera has, the more detail it can capture and the larger pictures can be without becoming blurry or\"grainy. \"  \nSource: How stuff Works  \n◼ Understanding:  \nWhat is the advantage of having more pixels in a picture?  \n_________________________________________________________________________________________________  \n_________________________________________________________________________________________________  \n______________________________________________________________ ___________________________________  \nACTIVITY 3: controlling light  \nDOCUMENT 4: aperture and shutter speed  \nJust as with film, a digital camera has to control the amount of light that reaches the sensor. The two components it uses to do this, the aperture and shutter speed, are also present on conventional cameras.  \nAperture: The size of the opening in the camera. The aperture is automatic in most digital cameras, but some allow manual adjustment to give professionals and hobbyists more control over the final image.  \nUpper right: with large aperture and slow shutter too much light passes to the film/sensor and the photo is overexposed. Lower left: with small aperture and fast shutter not enough light passes to the film/sensor and the photo is underexposed. Lower right: small aperture and slow shutter gives a correct exposured photo but shows motion blur.  \nSource: wikimedia commons  \nShutter speed: The amount of time that light can pass through the aperture. Shutter speed is a common term used to discuss exposure time, the effective length of time a camera's shutter is open. Slower shutter speeds are often selected to suggest movement in a still photograph of a moving subject. Fast shutter speeds freeze a moving subject on photograph.  \nSource: How stuff Works  \n◼ Understanding:  \nExplain in your own words the notion of aperture:  \n___________________________________________________________________","cbCaicY968rvprH9","https://ap.wps.com/l/cbCaicY968rvprH9","pdf",742598,"English","# ACTIVITY 1: what is a digital camera?\n## Understanding\n## Vocabulary\n# ACTIVITY 2: digital camera resolution\n## Understanding\n# ACTIVITY 3: controlling light\n## Understanding\n## True or False","[{\"question\":\"What is a digital camera and how does it differ from film cameras?\",\"answer\":\"A digital camera captures photographs in digital memory, while film cameras capture images on photographic film.
