i am using a Canon 1000D. Have read the manual and tried experimenting. i still do not understand how partial and center weighted metering works. After taking photos of the same object using the same exposure settings, it seems to be the same. Can anyone explain them to me?
Also, i do not understand how to properly use lock exposure and under what circumstances.
Here is a theoretical situation:
Supposing i would want to take a photo of my model which is placed in front of a desk lamp, therefore the model which is in the foreground would appear dark while the background is very bright due to the lamp. However, the model is at the bottom of the picture, therefore i would need to use the bottom auto focus point. how do i manipulate the settings to make the model appear brighter without over exposure and making the light from the lamp look like a nuclear blast?
