Common Camera Controls

Using the Zoom Lens

Turn on the camera and select Auto.

If the LCD display doesn't come on, press the joystick to turn it on.

Press and hold the W (zoom out) button on the rear of the camera until the display shows the widest view of the subject.

Press the shutter button on top of the camera to take a picture.

INTRODUCTION

Almost all digital cameras feature a zoom lens, which is a lens that can be adjusted to bring distant subjects closer or provide an overall view of a scene. Zoom lenses are usually referred to by the level of magnification from the lowest to the highest magnification. For example, a 4× optical zoom brings objects 4× closer at maximum zoom than at minimum zoom. In this task you learn how to adjust the zoom controls to frame your photo as you'd prefer using a Kodak EasyShare digital camera.


TIP

Getting the Wide View

Using the lens at its widest setting is useful for shooting groups indoors and for capturing the overall look of a building or scene.


Press and hold the T (zoom in) button until the display shows the largest view of the subject's details.

Press the shutter button on top of the camera to take a picture.

TIP

Optical to Digital Zoom

Most digital cameras feature an optical zoom as well as a digital zoom. When you zoom in on a subject, most cameras pause at maximum optical zoom before switching to digital zoom.


HINT

Use a Tripod

If your digital camera supports optical zoom ratios of 6× or larger, you might want to use a tripod to support your camera when you use maximum zoom. A tripod helps prevent camera shake, which can ruin your pictures.


HINT

Variations in Zoom Controls

Some digital cameras use a zoom control wheel around the shutter button, such as the Olympus C-4000 used in some tasks in this book.


Press and hold the T button to activate the digital zoom.

Release the T button after the display indicates you've activated digital zoom.

Press the shutter button on top of the camera to take a picture.

HINT

Keeping an Eye on Digital Zoom

Most digital cameras display a special icon on the LCD display to indicate when you use digital zoom. Digital zoom enlarges the pixels in the image, so pictures taken with it aren't as clear or sharp as those taken with optical zoom.


HINT

Using a Zoom Ring

Some zoom lenses, particularly those used on high-end fixed and interchangeable-lens SLR digital cameras, use a zoom ring on the lens itself. Turn it to zoom in or out.
