ok thanks mate, its something ive always wondered, how you determined your settings using an incidental
meter. So its only
aperture that gets determined by the
meter .. ok.
So.. if i was setting up an outdoor portrait shot and had my flash 2 metres from the model, I would test fire at the model and determine the required
aperture, and set my camera accordingly. Then to expose for the background, lets say a beach scene at dusk, I would
meter a seperate
exposure off the sky or whatever part of the scene, and then set my
shutter speed corresponding to the predetermined
aperture from the flash test shot ?? Now this would in theory give me an even
exposure and maintain ambient
light and detail in my background. But If I wanted to underexpose the background slightly, to create seperation of model from bg, I would set the
shutter speed so that my
meter indicated a 1
stop underexposure ?? Am I on the right track ??
