Sony DSC-D700 Digital Still Camera

Article excerpt

Sony is popular for its video and image capturing devices. The DSC-D700 is no exception in a successful line of still image cameras. This lightweight camera can be a valuable supplement for increasing multimedia and Web activities in educational institutions.

The DSC-D700 offers a high-resolution (1344 x 1024 pixels) and a lower-resolution (640 x 480 pixels) option. Another feature is the three-level compression rate: images are saved in JPEG format, ready to be posted on the Web. The uncompressed images (approximately 1 MB) are saved in a TIFF format. This ensures that the captured image is of a high quality, allowing for easier manipulation with image-processing software such as PhotoShop.

A limited number of uncompressed shots can be stored in the camera's memory before they are uploaded to a PC. The camera comes with a memory card of only 8 MB, upgradeable to 16 or 32 MB. Uploading, in contrast to other Sony digital still cameras (e.g. Mavica with its "floppy disk" upload), is accomplished solely through a proprietary PC card parallel port adapter. The software installation is fast and easy. However, the adapter's occasional refusal to recognize the card can necessitate restarting the computer. This, along with Macintosh incompatibility, can turn the upload into a painstaking and cumbersome ordeal.

The flash is small and useful only for close distances, yet a hot shoe provides the option to add an external flash. …
