Capturing and controlling digital images

Capturing and controlling digital images Great images are not made by digital cameras. They are made by photographers who understand what to look for and how to capture it. It is not about equipment. It is about how to creatively and effectively use the equipment to produce outstanding images for the yearbook.

Capturing and controlling digital images Photographers can work in these areas to improve the quality of images captured by the camera. Camera knowledge Camera handling Preliminary settings Focusing & metering Exposure control Reading light

Capturing and controlling digital images Improving image capture — camera knowledge One of the most basic prescriptions for better images is to read the camera manual and become familiar and comfortable with the camera’s controls and settings. Many problems with image quality can be traced back to mistakes in camera operation.

Capturing and controlling digital images Improving image capture — camera handling The left hand should always be placed under the camera and lens for a steady support. Elbows should be tucked tightly against the body for additional support. In vertical format, use the left arm and elbow for solid support. Before pressing the shutter, take a breath, let half of it out, and then gently press the shutter to capture the image.

Capturing and controlling digital images Improving image capture — preliminary settings Digital camera settings for image size and image quality are often the key to whether an image will make the grade as a yearbook photo. These two settings, often overlooked before assignment photos are made, determine the overall quality of the image file and the usable size of the image when it is printed in the yearbook.

Capturing and controlling digital images Improving image capture — preliminary settings The camera setting determines the overall pixel size of the image. Image files with greater pixel dimensions will produce images that can be run larger in the yearbook. Do not be tempted to get more images on a storage card by creating image files that can only produce small, low-quality printed pictures. Whatever image size is set at image capture determines all the pixels you will ever have to work with.

Capturing and controlling digital images Improving image capture — focusing & metering Pay attention to what you see in the viewfinder. There is an eyeful of information there to help you capture images that are sharp and properly exposed.

Capturing and controlling digital images Improving image capture — focusing & metering The focusing grid is the area the camera uses to determine sharp focus. • Put the critical focus area of the scene in this target to ensure sharpness. • Most cameras offer a variety of focus targets. Learn the difference and select the one that best suits your subject.

Capturing and controlling digital images Improving image capture — focusing & metering There also is a target grid for metering. • It is important to place the area of the scene to be metered inside the target area. • Use the exposure lock control on the camera to lock in the meter reading if you need to adjust the composition of the subject in the viewfinder.

Capturing and controlling digital images Improving image capture — exposure control Even though modern digital cameras offer accurate and powerful exposure control programs, it is still critical to make wise program exposure choices, and to pay attention to the aperture and shutter speed settings.

. Capturing and controlling digital images Improving image capture — exposure control The aperture setting selected during program exposure affects the final image in two important ways. One. The size of the opening determines the amount of light that strikes the digital sensor. Larger openings, represented by smaller numbers, let in more light.

The size of the opening also is a creative tool to determine what areas of the image will appear in sharp focus. This is called depth of field. The larger the opening, the shallower the depth of field and the smaller the area that appears in focus. This is helpful in getting the center of interest to stand out from the background.

Capturing and controlling digital images Improving image capture — exposure control Although digital cameras do not actually have a shutter, they do have a timing device to control exposure. This exposure time, or shutter speed, affects the final image in two important ways. • One. The exposure speed determines how long light is allowed to pass into the camera and expose the image sensor. • Two. The exposure speed also is a creative tool for stopping action or making action blur. Faster speed settings will freeze action and slower speeds will create blurred action.

Capturing and controlling digital images Improving image capture — reading the light It is all about the light. The right amount of light allows for proper exposure.

Capturing and controlling digital images Improving image capture — reading the light Too much variation between highlights and shadows can exceed the limits of the digital sensor to record detail, and leave some areas of the photo washed out and other areas in the dark.

Capturing and controlling digital images Improving image capture — reading the light The right mix of shadows and highlights can add visual interest and impact to a photo. Different times of day, like early morning and evening, produce more pleasant and interesting light than bright sun in the middle of the day.

Capturing and controlling digital images Improving image capture — reading the light The ISO setting on a digital camera controls the camera sensor’s sensitivity to light. Higher ISO numbers allow for photos to be made in lower levels of available light. The down side of higher numbers is the image static or noise that appears on the image. Always use the lowest ISO setting you can and still capture the image. If the lighting is too low, use the flash.

It is not about the equipment; it is about how to creatively and effectively use the equipment to produce outstanding images for the yearbook.
