So, if I am shooting two shots of the same scene using the camera's exposure meter and another using a light meter. Where I expect one meter or the other to indicate the de facto standard. If the camera's exposure meter is functioning as "kmac' stated: "The light meter has been designed and factory adjusted for that camera alone, the 111c, with all variables taken into consideration. It may not read exactly the same as other meters simply because it's designed for that one camera and hand-held meters might meter for different angles." So if the camera's meter is working, the images should be spot on while the images from the light meter should not as precise. And vice-versa, if the light meter is more correct. I will shoot some scenes manually setting the shutter and aperture for additional tests for comparison. So shooting +1 would not be best at this time since I am trying to establish the camera's baseline and determine what would be the best methods to employ henceforth.
