>>3488038>I tried them out on a street sign earlier there was virtually no difference between them, all other settings being equal.If the scene doesn't have too much contrast, and if you're pointing to something not too bright or too dark, the metering modes will give you more or less the same exposure.
The idea of a meter is that it will give you settings such that the end result will be middle grey in luminosity (which works because that's what most natural scenes look like in terms of luminosity).
In averaging mode, it'll read the whole scene and make it look on average middle grey. This doesn't work well with scenes that you want predominantly dark or predominantly white (for instance in your pic, you want your scene predominantly white/bright).
In center weighted mode, it will read only a patch in the center (where the camera is pointed at) and make that look middle grey. If you point it at something dark, it will brighten the picture (to make the dark spot appear middle grey), and vice versa if you point it to something bright.
Spot mode is the same as centre weighted, just a much smaller patch.
If you want brighter pics, put you camera in spot metering and point the spot at a dark part of the scene, and use those settings. If you want it even brighter, add exposure compensation.
