Ambient light .... manual exposure.
  • RubyRuby January 30
    A quick question.... you set your exposure up say for the brightest part of the white wedding dress in manual mode using the histogram method. So will your exposure (ambient) remain constant if you move around your subject 360 degrees? Cheers Ruby.

    Yes, as long as the part you are photographing has the exact same lighting conditions.

    You may need to evaluate the scene though in bright sunlight as to what you set the camera [manually] at. As any shadows of course will be very contrasty, but generally speaking once you set manual, no matter where you walk, frame, compose, zoom you will get the exact same exposure time and again.

    However, if the sunlight is falling on mainly the front of the subject, and you are shooting for that, no problem, but if sun is falling on back of the subject, and you want exposure correct for front [no flash] you will most definitely need to open up aperture/shutter/ISO to get to that correct exposure as you are shooting against the light and that could very easily be 1-2+ stops.

    Even if you are totally in shade, the area facing the open sky will have more light, than if you move to behind the subject to shoot against that open light, unless you are totally enclosed in greenery all sides, then it will be constant.

    Hope this makes sense.

    Keep this idea in mind ..
    Let's say you're shooting someone standing in front of a large window with soft window light streaming in ... when you move 180 away, keeping the same exposure, then you have a silhouette.

Howdy, Stranger!
