Reading the Exposure Chart
Reading the Exposure Chart
The chart on the back of the VS-210 allows you to determine the correct camera settings and flash-to-subject
distance for flash exposures. You can use the chart to determine exposure in three ways:
1. By aperture and flash-to-subject distance:
A. Select the aperture you want to use on the right side of the chart.
B.
Follow its horizontal line until it intersects with the vertical line of the flash-to-subject distance you want to use.
C. Follow the diagonal line at the intersection down to the ISO/ASA number at the left of the chart.
D. Set your digital camera’s ISO setting to the number indicated by the diagonal line, or use film that
has the indicated ISO/ASA speed.
2. By aperture and ISO:
A. Select the aperture you want to use on the right side of the chart.
B. Follow its horizontal line until it intersects with the diagonal line of the ISO/ASA setting you want to use.
C. Follow the vertical line at the intersection up to the flash-to-subject-distance scale at the top of the chart.
D. Position your subject at the distance indicated by the vertical line
