Tips and hints on taking pictures with your digital camera
The most critical element in a digital camera is the lens because all light must travel through the lens. Choose from traditional film camera makers, especially those renowned for their optical lens.
In digital cameras, the film is replaced by a small sensor chip - either CCD (charged Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) - which captures the image in a digital format.
To capture an image, light first travels through the lens. It is gathered as electrical charges by the sensor. The sensor, by itself, is incapable of perceiving colours, so it obtains colour data by means of a colour filter arranged above individual pixels. Image data gathered by the sensor is converted into digital signals, which is analysed and processed by the image processor which then gets written out onto a memory card.
Ensure that there is sufficient light in the background
It is recommended that you purchase a digital camera with a built-in flash for night shots. Use the camera's exposure compensation mode if there is too much light in the background.
Resolution is the measurement of an image size in pixels. Since the maximum available resolution of an image is constantly increasing, digital cameras use a process known as "compression" to reduce the data size of the image before it is stored. While this increases the number of pictures you can store on each memory card, there is a trade off in quality.
Digital Cameras store images in removable storage media such as
Dirt, dust and fingerprints impact the performance of your lens. And believe it or not, there is a right way and a wrong way to clean a lens. Do it right and you'll maintain peak optical performance. Do it wrong and you could scratch an expensive piece of photographic equipment.
Always consider a flash. Built-in flashes typically produce harsh shadows and edges, unnatural skin tones and "flat", washed-out images. So when using electronic flashes, don't use it head on. Instead, diffuse the flash using various accessories such as bounce cards or soft boxes, or aimed to reflect from other surfaces, also known as "bounce flash".
