Metal 

finding family of angles

1. position a white target where you think the FA would be. the less sure you are the bigger the surface

2. place a light at the camera lens 

3. aim light at the nearest point  the light will reflect off metal and onto test surface. mark as many points as you need to mark the FA 

4. study the position and shape of the marked area ******this is a good place to start making it quicker to find the FA 

EXPOSURE 

spot meter reading on metal remembering to expose 2-3 stops more than meter reading. ****remember meter tells us 18%
