  • Nikon | Imaging Products | DSLR Camera Basics | White Balance
    Subjects may be lit by a number of different light sources including sunlight incandescent bulbs and fluorescent lighting Although to the naked eye all these different light sources may appear colorless in fact they emit light of different colors The image sensor in a digital camera will reproduce these color differences just as they are with the result that without additional processing the color of the photograph would appear to change according to the light source Auto white balance automatically processes the image to remove unwanted color casts by for example making photographs taken under incandescent bulbs more blue to correct the reddish cast of this type of lighting Normally auto white balance will produce the desired results without the photographer having to worry about the type of lighting If auto white balance does not produce the desired results the photographer can choose from a number of fixed white balance options according to the weather or the light source The photographer can also choose a setting for direct sunlight or incandescent lighting to introduce a deliberate red or blue cast according to their creative intent Auto white balance Direct sunlight selected for a red cast Incandescent selected for a blue

    exposure by adjusting shutter speed aperture f number and ISO sensitivity according to the brightness of the subject which is measured using the camera s built in metering sensor The camera does not simply measure the overall brightness of the frame but measures brightness separately in multiple areas of the frame The metering mode determines which areas of the frame are used by the camera to measure subject brightness and how the camera sets exposure Normally the camera uses matrix metering in which it divides a wide area of the frame into multiple segments and sets exposure based on a variety of information including subject brightness and color You can also choose center weighted metering in which the camera assigns the greatest weight to the center of the frame and spot metering in which the camera meters the area around the selected focus point Choosing a metering method according to the scene and your creative intent allows you to achieve results that better mirror your artistic vision Matrix Metering Red circle represents center metering area Matrix metering ensures a balance between light and dark areas Center weighted Metering Red circle represents center metering area Exposure is set correctly for the

    does not simply measure the overall brightness of the subject but measures brightness separately in multiple areas of the frame The method used to choose the areas metered and how they are metered is referred to as the metering method or metering mode Normally the camera uses matrix metering metering multiple segments covering a wide area of the frame and adjusting exposure based on such information as brightness and color Other metering methods include center weighted metering in which the center of the frame is assigned the greatest weight in determining exposure and spot metering in which the camera meters only the area around the current focus area By choosing methods suited to their subjects and creative intent photographers can achieve results that are closer to their goals In viewfinder photography exposure is measured from light falling not on the image sensor but on a ded icated metering sensor which may produce results that differ from those obtained during live view During movie recording exposure is set using matrix metering Matrix Metering Exposure is adjusted for a balance between bright and dark areas of the frame Note Red lines are artist s concept only and do not correspond to actual

  • Nikon | Imaging Products | DSLR Camera Basics | Perspective
    or long telephoto lenses Wide angle lenses have wide angles of view increasing the difference in the apparent sizes of objects that are at different distances from the camera In other words nearby objects appear larger and distant objects smaller Telephoto lenses in contrast have small angles of view decreasing the difference in the apparent sizes of objects that are at different distances from the camera This effect can be used to exaggerate or reduce the effects of perspective by changing the focal length of the lens Imagine photographing a subject at the same apparent size using lenses with different focal lengths Despite the difference in focal length you will be able to photograph the subject so that it appears to be the same size in the frame but only by moving the camera with a wide angle lens you will have to be close to your subject while with a telephoto lens you will have to be farther away And although the subject will be the same size within the frame the apparent distance to the background will change At wide angles more of the background will be visible and background objects will appear to be farther away With telephoto lenses on the other hand less of the background will be visible and background objects will appear to be closer Wide angle lens The illustration is an artist s conception More of the background is visible and background objects appear to be farther away Telephoto lens The illustration is an artist s conception Less of the background is visible and background objects appear to be closer Different perspectives Focal length 12 mm Focal length 24 mm Focal length 50 mm Focal length 70 mm Focal length 135 mm Focal length 200 mm In these photographs we changed the distance
