Photography Tips for Beginners - Exposure recompense and Metering Modes
Exposure payment is what you can do to override the exposure settings set by the camera's metering system. Assuming you have set the Iso to a exact level, eg. Iso 100, the metering principles in your camera measures the estimate of light in the photo and tells you the gap ,break and shutter speed needed for a spoton exposure. There are ordinarily 3 types of metering methods used in today's Dslr cameras.
Multi-Segment Metering
Most cameras use multi-segment metering as the default metering system. In Nikon cameras this is called Matrix Metering. In Canon cameras it is referred to as Evaluative Metering. Other brands of camera may have slightly dissimilar terminology. This metering principles measures the glow in any areas in the photo and finds an median (emphasis varies depending on the camera). This type of metering can be fooled by more absorbing lighting conditions such as strong backlighting.
Strong backlighting conditions are where the estimate of light on the background is far more intense than the estimate of light on the foreground area. This ordinarily happens when you shoot a field indoors, with a brightly lit outdoor background.
Ideal lighting conditions are where there is a similar estimate of light illuminating both the background and foreground. Ideal lighting is where the camera's multi-segment metering does a good job.
Spot Metering
Nikon calls it Spot Metering, while Canon calls it Partial Metering. For pinpoint control on the area for which the camera measures brightness, use spot metering if it's available. This metering principles only samples a very small point within the photo (usually in the center) instead of any areas. You can press the shutter issue halfway to meter the desired area, hold the Ae lock button, and then re-frame the shot.
Alternatively, take an exposure reading with spot metering, note the gap ,break and shutter speed, and switch to hand-operated exposure mode. This enables you to focus on a field which isn't what you measured the exposure on.
Center Weighted Metering
This metering formula is designed for a uncomplicated uncomplicated portrait of a person, positioned in the center of the frame. It measures the center area (in some cameras, the estimate of area measured can be set by the user) and bases its exposure advice on this area.
Exposure Compensation
Normally, exposure payment is used in the semi-auto modes such as gap ,break Priority and Shutter Priority. This puts a distinct degree of control (though not as faultless as hand-operated exposure) in the hands of the photographer. In gap ,break Priority mode, you can tell the camera to expose brighter by pressing the Ev button (usually indicated by a +/- icon) and shifting the control dial towards the distinct (eg. +1 which means 1 stop brighter). This is helpful in backlit conditions. In Nikon cameras the range of adjustment is all the way to +5.
In hand-operated exposure mode, you are essentially performing exposure payment if you are using a Aperture/Shutter mixture that is not what is advised by the exposure meter.
