If you travel a lot because of the nature of your work or if you simply like to travel to explore new places, you surely would want to document your adventure in color. And one of the best ways to do that would be to use a digital camera. But wait, aren’t they bulky, you might ask? Some are, but there are also those that are lightweight and compact to save you the hassle of dragging around a rather heavy and bulky one. These cameras are perfect for you, the traveler.Canon A470 - can easily fit into your pocket or your backpack.Olympus 1030SW - waterproof up to 33 feet and shockproof.Nikon D60 - a digital SLR for prosumers and pros who travel a lot.For more info: Digital Camera HQImage source: Digital Camera HQÂ

Many devices include digital cameras built into or integrated into them. For example, mobile phones like Ericsson and Nokia often include digital cameras; those that do are sometimes known as camera phones. Other small electronic devices (especially those used for communication) such as PDAs, laptops and BlackBerry devices often contain an integral digital camera. Additionally, some digital camcorders contain a digital camera built into them.Due to the limited storage capacity and general emphasis on convenience rather than image quality in such integrated or converged devices, the vast majority of these devices store images in the lousy but compact JPEG file format.

- Hold the camera with your right hand. Support the camera or lens with your left hand. Do not block the autofocus, flash, port or lens.
- Photos are stored in the camera’s buffer–internal memory. When the buffer becomes full, one or more image will be transferred to the memory card before more pictures can be taken.
- Do not open the battery or the covers of the memory while you are saving images. This will cause failure of the image to be saved, and cause damage of the memory card.
- You can adjust the brightness of your monitor.
- Turn off the camera when not in use.

Many digital cameras can connect directly to a computer to transfer data:
- Early cameras used the PC serial port. USB is now the most widely used method ( Most cameras are viewable as USB Mass Storage), though some have a FireWire port. Some cameras use USB PTP mode for connection instead of USB MSC; some offer both modes.
- Other cameras use wireless connections, via Bluetooth or IEEE 802.11 Wi-Fi, such as the Kodak EasyShare One.
A common alternative is the use of a card reader which may be capable of reading several types of storage media, as well as high speed transfer of data to the computer. Many modern cameras offer the PictBridge standard, which allows sending data directly to printers without the need of a computer. -Wikipedia

Image resolution of a digital camera is often limited by the camera sensor (typically a CCD or CMOS chip) that turns light into discrete signals, replacing the job of film in traditional photography. The sensor is made up of millions of “buckets” that essentially count the number of photons that strike the sensor. This means that the brighter the image at that point the larger of a value that is read for that pixel. Depending on the physical structure of the sensor a color filter array may be used which requires a demosaicing/interpolation algorithm. The number of resulting pixels in the image determines its “pixel count”. For example, an image 640×480 big would have 307,200 pixels or is approximately 307 kilopixel image; and an image 3872×2592 big would have 10,036,224 pixels or is approximately a 10 megapixel image. -Wikipedia

Here are things you need to know outright when using a digital camera:
- Enter the date or time (if this is the first time you will use your digicam or if the batteries have been dead for a long time already. It will be easier to organize, find and identify your images.
- Learn what the icons mean. Check the camera settings on the control panel and viewfinder. The number of pictures you can shoot will depend on your settings and status of battery change.
- Remember, if you are storing an image and you turn off your camera, the image will continue to be saved before your camera fully shuts down.
- Generally, shutter buttons have two stages. Press your camera halfway down–the camera will set a focus and exposure. When you are ready to capture your picture, press the button the rest of the way. With some cameras, you can press the button all the way. A delay will occur before the picture is captured, in order for it to focus.
- See if the camera has a diopter adjustment that will make it sharper, if you notice that the view finder is blurry.

Common formats for digital camera images are the Joint Photography Experts Group standard (JPEG) and Tagged Image File Format (TIFF).
Many cameras, especially professional or DSLR cameras, support a Raw format. A raw image is the unprocessed set of pixel data directly from the camera’s sensor.
Other formats that are used in cameras but not for pictures are the Design Rule for Camera Format (DCF), an ISO specification for the camera’s internal file structure and naming, Digital Print Order Format (DPOF), which dictates what order images are to be printed in and how many copies, and the Exchangeable Image File Format (Exif), which uses metadata tags to document the camera settings and date and time for image files. -Wikipedia
