Difficult metering situations
When the subject is against the light or the background is too bright campared to the subject, there are a few ways of handling the situation
Any of the following may be applied.
.Spot metering- that is measure through the spot on the most important area.
Exposure compensation- that is over expose the subject by 1 stop
Flash- sometimes spot or exposure compensation do not work as well as a bounced flash does.
Move closer to the subject or zoom in so as to include only the main subject and not the background. Lock the exposure using the exposure lock button and then recompose the desired frame to release the shutter.
If a long lens is being used for a portrait which is mainly filling most of the area of the frame, exposure compensation may not be required. remember, light travels in straight lines and most of the light reaching the sensor maybe only from the subject.
