Looking at different digital cameras, even temperately costing digital cameras have arrangements for exposure compensation settings. To explain in a bit detail, the exposure compensation allows the users to control the amount of light entering the lens. And thereby the illumination of the photograph is decided. Exposure compensation can be altered manually or by the help of a digital camera’s exposure compensation setting that lets one override the metered exposure set inside the digital camera itself. Strictly speaking, the exposure values provide an expedient line of attack to put a figure on the available light intensity and therefore exposure.
As per general norms of the users of digital cameras, certain standards exist for selecting such values. These values are specifically known as Exposure Values (EV). Selecting an up to standard Exposure Values (EV) helps maintain the details contained in dark areas of a photo, or diminish the more than usually bright areas. Again, looking from technical point of view, the Exposure Values are numbers that refer to an assortment of combinations of apertures of lenses and shutter speed respectively. They have a selective range of values, ranging between -2 to +2 Exposure Values (EV). As a general rule positive exposure settings are used for cases where bulky areas of a scene are especially bright such as taking pictures of a snow scene and also during times of photographing when the background is a good deal brighter than the focal area under consideration. Also, negative exposure settings are used for cases where bulky areas of a scene are especially dark and also during times of photographing when the background is a good deal darker than the fore area under consideration.
One point that is worth noting is that light meters cannot see color. They deliver every scene as 18% middle gray and become accustomed to the exposure accordingly. And most digital cameras will allows a photographer to compensate the exposure by 1 to 2 EV plus or minus in 1/3 or 1/2 stop increments. A very important realization for any photographer is that the right exposure is only “correct” in the eye of the photographer; Exposure Value compensation can also be used as a creative tool.
Extending the discussion further we can state that just about most of the digital cameras has a macro mode. Each of these digital cameras can be verified of having the macro mode because for each of them one of the menu buttons will have an icon of a flower on it. This is the macro mode button invariably. And thus has the specific technology built in. The macro mode button, when pressed, switches the camera into a special close focus mode and many allow the photographer to shoot less than 10cm from the picture subject. Many cameras of reputed companies like Nikon and Ricoh allows the users to be as close as 3cm from the picture subject that permits barely credible close ups of tiny objects such as little insects. The macro mode has a greater variety of applications in security measurements too. At times macro mode may be also useful for making photographic records of priced jewels for insurance purposes in order to prevent theft and fraudulent activities.
The macro mode is more often than not present on the menu button that as well has an icon of two triangles symbolizing mountains (or rather landscape mode) and sometimes MF (manual focus) too. This button has to be pressed several times until the flower icon appears on the viewing LCD. A number of digital cameras then subsequently by design shift into a particular precinct on the zoom lens making a mechanical sound as the zoom reset. While using a digital camera macro mode it must be noted that it is harder to focus for the digital camera instantly, so it takes a bit of time for adjustment. Thus the users need not hurry while using the digital camera macro mode. As the subject comes in focus the depth-of-field also increases. On the other hand, the depth-of-field is controlled by the camera’s aperture. Most digital cameras are full automatic and this setting cannot be changed. Thus patience becomes a virtue while using the digital camera in their macro mode.
Much has already been discussed about the digital camera macro mode. It can be stated here that the digital camera macro mode is a really intricate feature. And every delicate object or subject needs to be handled with care. To really cherish the beauty of the digital camera macro modes the users require developing the expertise and also building a kind of patience that is necessary to cerate beauty in art and object.
