Digital Camera

One of the advantages of a digital camera that can not be found in an analog camera is the ability of digital camera to connect directly to the computer. This is certainly an advantage for the photographer to be able to select the photos stored in the camera. They can choose the best photos or can edit before printing.

Having selected the best photographs, the photographer will make the transfer to the computer. Its required special interface, so that the camera and computer can communicate with each other. Commonly, known term is the data transfer.

There are several ways that can be done to transfer the data from a digital camera to a computer. Maybe not all the way is owned by a digital camera, but at least there is one way that has been provided by the digital cameras that can perform data transfer to a computer.

• At the start of production, a digital camera using the serial port on the computer. The weakness of this connection is a slow time of data transfer. Currently, connected via the serial port is not used anymore.
• Using a USB (Universal Serial Bus) connection is a more practical and faster than the serial port. USB connection is becoming the most widely used today and has become the standard interface of data transfer between a digital camera to a computer.
• Using a FireWire connection. This connection is copyright Apple Inc.. known as IEEE 1394 interface. The advantages of this connection is also the same as the connection using the USB interface.
• Using a USB PTP (Picture Transfer Protocol) connection. This connection can be used as a way to connect a USB connection in addition to MSC (Mass Storage Device). Currently, some computers have provided two ways that connection.
• Using a Wireless connection. Currently, some digital cameras have been equipped with a wireless connection to connect to a computer. Practical because it does not use a longer cable. Although wireless, the speed of data transfer is not in doubt.
• Using a storage media reader tool called Card Reader. Storage media in a digital camera will be released and then fed to the Card Reader. Card Reader will be connected to a computer so that the data derived from a digital camera can be opened in the computer. Today, the use of Card Reader has become a standard alternative because this tool is able to read various types of storage media, and enables high data transfer rates also.

One of the advantages Card Reader that no other connection is the data transfer takes place when the battery power is not needed. This is very helpful if a photographer had forgotten to bring a spare battery.

Advances in technology also affected the camera world. Nowadays almost all digital cameras have the ability to record a direct transfer to a printer without using a computer. The photographers only need to choose the best photos on the camera's LCD screen through them, then just connect to the printer (wired or wireless) and print directly. Practical isn’t it?
