Digital Imaging. Like the film camera, digital imaging uses a lens to focus the image on a focal plane. While the film camera relies on film to capture the image, the digital uses a sensor. As light strikes the array of picture elements (pixels) that make up the sensor, it’s converted to a current that’s passed on to a digital or A-D converter. From the A-D converter, algorithms are applied to the signal, converting it to a digital image file.

File Compression or “Quality”
In addition to high- and low-resolution settings, many digital cameras provide options for selecting the amount of file compression applied when photos are stored in memory. Higher-quality settings use less compression, but take up more storage space.
Flash Memory
Flash memory is “non-volatile,” meaning it retains the photo files and user settings even if the power source is removed for a long period of time. Many cameras have electronic components that preserve the memory contents for a few minutes to allow time to change batteries. However, it’s always wise to download photos before changing batteries or storing the camera away.
Interpolation
A method of increasing the number of pixels in an image after it is photographed. The pixels actually captured by the camera’s sensor are rapidly analyzed by software that creates and adds new similar pixels to the photo file. Some Bushnell® imaging optics provide user options for higher interpolated resolution settings.
Pixels and Megapixels
Pixels are the tiny squares of color – like dots on a newspaper photo or grains on a photographic print – that make up a digital image. The higher the pixel count, the higher the photographic resolution. A megapixel (MP) equals one million pixels.
Resolution and File Size
The number of pixels used to produce a digital photo is the primary factor that determines resolution, or ability to reproduce fine detail. More pixels equal higher resolution, and a larger data file.
Storage Cards: Digital “Film”
These are small removable “flash” memory devices used to hold image data from a digital camera, reducing or eliminating the need for high-capacity internal memory. Most Bushnell digital imaging optics have a slot, for an SD (Secure Digital) card, the most common type currently used.
Camera Settings
The “default” automatic setting on digital cameras works fine in most situations, but some cameras will also let the user override “auto” and adjust one or more of the following if necessary or preferred:
EV (Exposure Value): Also known as exposure compensation. Allows setting deliberate under- or overexposure by a fine amount, such as “+1.5 EV” (one and a half steps overexposed).
ISO (Sensitivity): As with film, low ISO numbers (100–200) will produce the highest quality but require the most light. Higher ISO settings will allow photos in low light without flash, or faster shutter speeds to stop action, but with increasingly noticeable digital “noise.”
Scene Presets: Some cameras let the user select from several preprogrammed “scenes,” which optimize internal camera settings (aperture, shutter speed, point of focus, light metering) for common types of subjects or situations, most commonly Landscape, Sports/Action, Portrait and Night Scene.

Sync Focus
Now on our ImageView spotting scope and Instant Replay binoculars, the Sync Focus feature is a parallel focus system that sharpens the digital image and the image through the scope’s or binos’ optics simultaneously. The synchronized light path also permits the user to switch between viewing through the camera’s LCD and the scope or binocular’s eyepiece.
USB Mass Storage
Cameras with USB mass storage don’t need a driver for Windows XP or Vista. Connect the camera to your PC, and it will be identified as a “Removable Disk,” just as if it were an external hard drive. Your photo files are stored in a folder on this “disk,” and can be copied or moved to the location of your choice or opened directly from the camera within your photo software.
White Balance: Auto white balance identifies a white reference point (wall, clouds, etc.) in a scene and applies overall color correction if needed, so whites retain a neutral appearance. If this produces poor results, presets for daylight, cloudy, tungsten and fluorescent lighting are often available.
Special Features
Self Timer: When selected, the photo is taken following a short delay after the shutter button is pressed. Used to prevent camera shake, or to include yourself in the photo.
Sequential Shot: Shoots a quick burst of multiple frames (usually 3–5 in a row), to increase chances of capturing the action.
Movie Mode: Allows the camera to shoot and play back short video clips. These are usually stored in the common “avi” format, and can be played on any computer with Windows Media Player, QuickTime, or other software.
