1. Many DSLR cameras have systems which help in enhancing the dynamic range of an image. Some examples of this feature are Canons Auto Lighting Optimizer and Nikons Active D-Lighting.
2. Evaluative metering is known as the catchall mode which allows photographers to use the cameras light metering system to capture the whole frame. The camera then selects the appropriate exposure setting for providing a good balance. This kind of metering is also known as multi-segment or average metering.

3. The brightness of the scene is considered equivalent to a midtone by the camera. This helps the photographers to focus on a frame with a very light subject, such as a winter landscape or a light, sandy beach. The camera then automatically reduces the exposure by rendering it to a midtone. Photographers can use the exposure compensation control to regulate the exposure intensity of the scene by increasing its value over the value suggested by the camera.
4. It is necessary for photographers to keep a watch over the histogram view when they are increasing the exposure value. This can be done by sliding the trace until it reaches the extreme right of the scale. However, care should be taken as too much of exposure can cause a lot of highlights to burn out.
5. Like in an instant camera, the evaluative mode is considered to be an effective way for using metering in a DSLR camera as well. When using the evaluative mode, dial in an appropriate amount of +/-EV (Exposure Value). This exposure value is also termed as exposure compensation. An example of this is applying exposure compensation between +2EV and +3EV in a heavily backlit portrait. This hels in getting vibrant and lively skin tones in focus, while the background is white.
6. It is preferable to apply negative exposure compensation when shooting a subject against a dark background. This helps in getting the subject exposed accurately even in low light conditions.
7. Centreweighted technique helps in giving metering prominence to the central region of the frame. Apart from centreweighted metering, there are also partial and spot metering available for DSLR cameras. These metering techniques are used when the photographer wants to discard anything that is beyond the small and tiny areas of the frame.
In order to know more about these metering techniques, photographers need to attend workshops that are conducted by photography schools. These workshops are great for understanding various photography skills which includes adjusting the aperture, shutter speed and ISO. These basics prove to be the building blocks for learning about exposure. So, beginner photographers need to attend special workshops conducted by photography schools to help understand exposure control and metering techniques in more detail.
8. Such workshops about exposure control and metering techniques can help photographers to gain indepth knowledge about photography. The workshops conducted by photography schools can thus prove useful for understanding how to fully control a DSLR camera.
When it comes to learning photography, basics of exposure are very important. They help photographers to click great pictures by choosing the best camera exposure and metering settings.
