The Canon PowerShot A3100IS comes with a 4x optical zoom lens that enables you to capture objects even at a distance with clarity.
Image Sensor
Consists of a silicon-based chip which captures the image projected at the lens by transforming the optical image into an electronic signal which then gets processed by the camera’s processor. The Canon PowerShot A3100IS has this 12.1 mega pixel CCD image sensor that produces high-quality images.
Processor
This gives life to the device by processing the electronic signals acquired from the image sensor into a digital image. It also performs the task of controlling the functions and features of the camera. The Canon PowerShot A3100IS has the DIGIC III processor, which provides faster image processing yet with accurate projection.
Display
Display: A 2.7-inch LCD handles preview and playback, sharp enough to actually tell if a shot’s in focus before you move on.
Storage: SD, SDHC, and SDXC cards all work, so you’re not locked into anything proprietary.
Battery: Rechargeable lithium-ion, rated for about 230 shots a charge — middling, but workable for a day out.
All Features of Digital Cameras
Digital cameras, remarkable as they are, come equipped with some versatile features that suit everyone with different functionalities in photography. The most common features of digital cameras are:
Image Resolution
However, in reality, image resolution refers to the density of pixels forming an image. A picture of higher resolution will provide greater detail and clarity. The camera has a maximum resolution of up to 4000 by 3000 pixels here the Canon PowerShot A3100IS.
ISO Sensitivity
ISO Sensitivity refers to how sensitive a camera is in capturing the light. Higher ISO makes a camera more sensitive in taking a photograph in the low light, thus making it possible to take really fine images. Canon PowerShot A3100IS ISO sensitivity ranges between 80 and 1600.
Shutter Speed
Shutter speed indicates how much time a shutter is open in a camera from which the light enters to take the image. Fast shutter speed is to take object the moving quickly, while slow shutter speed is for complete darkness. The Canon PowerShot A3100IS has a maximum shutter speed of 1/1600 secs and at minimum has 15 seconds.
Aperture: Wide open, more light gets in and the background blurs out. Stop it down and you get more of the scene in focus, less light. The A3100IS ranges from f/2.7 to f/8.0.
White balance: Reads the lighting and adjusts color automatically – daylight, cloudy, tungsten, fluorescent presets, plus a custom setting if none of those match.
Autofocus: Locks onto the subject on its own, with face detection, center-point, and manual modes depending on what you’re shooting.
Image stabilization: Optical Image Stabilization shifts internally to counter hand shake, which means fewer blurry handheld shots, especially at slower shutter speeds.

Benefits of Cameras
Digital cameras come with certain advantages in contrast to their predecessors, the film cameras.
Immediate review and editing Images can be checked and edited in a couple of seconds after having been taken on a digital camera, whereas in the case of a film camera, the picture would not have been processed until after the film was developed. Editing options available for the Canon PowerShot A3100IS camera include molding, rotation, red-eye correction, and color adjustments.
Images of superior quality In general, images taken with a digital camera are of really high quality and may even be scaled to great sizes without losing their quality. The Canon PowerShot A3100IS provides well-defined and less defined images due to the influencing factor of high-resolution image sensors and optics.
Flexibility These cameras can be used for such things as portrait, landscape, and action photography. The shooting modes of the Canon PowerShot A3100IS include auto, portrait, landscape, and sports.
Easy to Share and Print Since sharing and printing digital images is easy. Canon PowerShot A3100IS has USB ports to transfer images to computers for furthering editing and sharing. It is also possible to print images directly from the camera with PictBridge-enabled printers.
