Due to microelectronic advances the ability to manufacture precise, smart, but inexpensive light metering systems has become possible. With all its features a normal digital camera can be compared with a hi-end 35-mm device – for example light measurement in 256 points of a picture. But the final decision about exposure is made by the software in the microcontroller, and that has no idea about the subject, only the brightness from many points. If some places are too dark or too bright, the logic of the software will try to find a compromises and smooth the levels. It’s not really required every time and in these instances you may get something strange and/or inexpressive.
