Features of Digital Cameras

Digital cameras possess features that make them more desirable as educational tools than traditional cameras or even video cameras. For example, they don’t require the inconvenience of loading film, but instead use a disk to record and store images. Also, they function well in a variety of lighting situations. The instant viewing of your fresh pictures is even faster than a Polaroid, and yet most models are lightweight and smaller than the standard 35mm. Using the camera is, however, exactly the same ? just point and click. 

One of the nicest features of digital cameras is that they can store pictures almost forever because the disc can be overwritten. So if you don't like a picture you’ve taken, you can record over it. 

Remember that, in digital cameras, images are stored in digital format. This means that, whether stored on floppy disc or on the camera’s internal drive, the image is ready to be received by a computer and/or processed by image editing software such as adobe printshop or microsoft paint. The image is transmitted to the computer via a cable that connects the camera and the computer when you are ready to transfer the image.

Once transmitted to the computer’s hard drive, the image can be stored in a folder the same way text documents are stored. 

Activity 1: Taking a Photograph and filing it.

Select a subject. Make sure lens cap is off and the camera is turned on. Focus and frame the picture, taking note of the lighting. Most digital cameras don’t use a flash, but if the subject is too dimly lit, it may not come out well.
