Know your Digital Camera



Little do most casual users know about the features they have at their disposal when they purchase a digital camera. Below are some information about various aspects of your digital camera that you need to know to take that perfect shot.

Zoom
Zoom lens is a must on any digital camera as they help capture more on the subject that will be the main focus of your snapshot. As the name suggests, with a zoom lens you can take a closer shot of the subject without ever physically moving closer.

Most digital cameras these days sport a zoom function, which may be anything from 3X to even 24X, but usually that number is divided into optical zoom and digital zoom. In actual functionality, it’s only the optical zoom level that matters since that’s what relates to the physical capacity of the lens. Digital zoom only enlarges a selected part of the image giving you a simulation of a zoom, while in reality it’s only stretching the picture causing a loss in image quality. It’s best to turn off the digital zoom function in your camera if you’re stringent about the quality of your photos. Optical zoom can be anything from 3X to even 12X.

Flash
Many casual photographers fail to see the relevance of the flash function besides ‘making faces visible in the dark’. If you happen to be one of them, then pay attention, there’s a lot you can do with your integrated flash. For starters, some digital cameras allow you to change the intensity level of the flash to plus (for higher flash output) or minus (lower flash output) depending on your requirement. For optimum effects in low light, its best to move the subject as close to a natural source of light like a window with sunlight falling through. It’s also recommended to turn on all the lights in the room so that the background is not left completely dark. Flash can also be used in daylight photography. For example, if the subject is standing right in front of the sun, you can use fill-flash to illuminate the subject so it doesn’t come blacked out. You can also use fill-flash to eliminate dark, shadowy areas that lack detail.

Exposure
As the term ‘photography’ suggests, light is the soul of your photograph. But be it digital or film photography, with too much light the picture will appear washed out and with too little light the picture appears dark and muddy. Exposure is the measure of the amount of light used to create a photo, and that’s exactly what makes a good photograph.

Most digital cameras use auto exposure to set the appropriate level of light required for a shot. All you need to do is press the shutter button half way down and let the camera take a few seconds to adjust the aperture and shutter speed. However, it is not always recommended to shoot on the recommended exposure levels. Try to adjust the exposure levels manually to get your desired level of brightness on the end result.

White Balance
White balance is used by digital cameras to keep the colors looking as natural as possible in the picture. To do so, the camera analyses the scene to determine which area is truly white and adjusts itself to the rest of the scene accordingly. If the level of one color (e.g. red) appears too high on the white part, the camera will automatically adjust itself to remove the same level of red from the rest of the picture to make it appear more natural.

Though most cameras do a pretty good job of adjusting the white balance, it is always a good idea to manually adjust the white balance in some lighting situations. For example, when a room is only lit with a yellow light bulb, the camera may have a tough time adjusting the white level automatically. You can easily set the white level to high through the camera’s menu system and thus get better results.

Scene Modes
Any digital camera worth its mettle has various scene modes that act as presets for most common situations. The camera adjusts its aperture, shuttle speed and exposure to get a desired level. The most common scene modes are:

Portrait Mode: It is perfect for close ups and macro shots as it creates a reduced depth-of-field effect in which the subject is in sharp focus while the background and the foreground is blurred out.

Landscape Mode: It works well when you want everything in the scene to be in sharp focus.

Sports Mode: It sets the camera to a high shutter speed and continuous auto-focus to clearly capture a fast moving subject.

Other popular modes included on most cameras include the night shot mode that helps you shoot night photos of surroundings and people without the need for any special accessories or skills! Manual Mode is another interesting although risky mode if you are a beginner with no knowledge of photography. It is in your interests that you leave the camera set to Auto mode where everything is taken care of at least initially. You can get creative slowly as you start grasping the basics better.
