[QUOTE="WayneF, post: 583187, member: 12496"] Things will go much better and easier if you stop and think about it being Reflective metering. The color black is reflected from the suit, and black does not reflect light well, so the meter reads low (it is low), and the camera will overexpose it trying to get it up to middle. The white brides dress reflects much light and reads high (it is high), and the camera will underexpose it trying to keep it at the middle. Middle because the dumb camera has no smart to know it is a suit or a dress or an elephant or a cloud. This "middle" concept is all because the camera simply has no human brain and experience helping it. It's just a dumb chip. It only sees a blob of light, and has no clue it is a dark suit or a white dress. That has no meaning to a chip. Middle is its best guess, not too dark, not too bright. The photographers brain and experience is expected to help identify what the subject is. Photography has expected this help from human brain power since light meters were invented. For humans, it's not that hard with a bit of experience, simply just first look at the subject and give it a bit of thought. We quickly learn what to expect. However, an incident meter instead just directly reads the actual light level incident on the subject (does not see the subject, is not influenced by the subject), and it normally gets it just about right. The meter still tries to put the light in the middle, but now at that correct level, black things come out black, and white things come out white (instead of both gray). But the incident meter has to be used at the subjects location, not as convenient as just aiming the camera from afar. Incident cannot be used built into the camera at camera location. Reflected meters only see the light reflected from the subjects colors. But photographers soon learn how to help their camera meter too. It is a big part of photography. [/QUOTE]
