The answer to last weeks question
You are taking a portrait with the sun behind your subject and you are using flash to balance the exposure on their face. Camera settings are Av mode at f/8 ISO 200. How do you darken the background?
This question seemed to catch a few of you out, though in truth the majority of you did get it right. It is further proof that flash is still scary for some! Anyway, on to the answer. It’s actually quite simple, if you want to darken the background, you need to increase the shutter speed. Given that the settings were being made in Av, adjusting the exposure compensation will adjust the shutter speed not the aperture. Therefore, using negative exposure compensation to record less light will be achieved by the camera increasing the shutter speed and hence darkening the background light. Al other things being equal, the light on the subject, produced by the flash, will not change at all.
