Thank you ExplorerZ.
If we are to say that exposure compensation is to adjust the value in a third stops (1/3 stops)..doesn't it make sense to adjust the aperture/shutter speed/ISO instead..as most of the DSLR comes with 1/3 stops adjustments..
E.g. At f/5.6, 1/125 for a EV compensation of -0.7
We can set to f/7.1, 1/125 or f/5.6, 1/200...Is this equivalent to a -0.7EV compensation?
But then, how about manual/film SLR? The older version of cameras are all mechanically controlled, and film speed depends on what you have loaded..hence the setting available are rather fixed..but it still does offer exposure compensation..How does it work for manual/film SLR then?
