Studio Lighting Explained
What is the 1 and 2 / 3 rule for studio lighting?
I'm doing a portrait of study at the university of tomorrow in the study and still I'm a little disturbed by the light metering rules, especially since digital cameras have many diaphragms between. I do a portrait of stock standard before to be creative with lighting. I will use a box of soft light hair and light background. Can someone tell me? Another name 3:1
A proportion lighting ratio of 3:1 has a 1 stop difference between the key and fill light. Picture it this way. Place the main or key light on the one hand, his right of option or left so that the lights on one side of the face completely and partially across the lights. Then place the fill light on the lens axis, above and behind the lens. The lens is usually set at eye level, the fill light behind and above it. Adjust the power to the lights so that the key light is twice as bright as filling, ie a stop brighter than the fill light. You now have 2 units of light from the main light and 1 unit of light from the fill light. The fill light 1 unit light on the dark side of the face and at the height of the face, at the same time due to its position on the axis of the lens. A unit of light filling the shadow side and 2 +1 units in the light of the key and fill lights on the light side of the face. A lighting ratio of 1:3.
