Ready-Light @
Built into the back of the SB-ll's flash head is a ready- light which comes on as soon as the speedlight is recycled and ready to fire. As an additional feature, the ready- light blinks if the speedlight fires at its maximum output indicating that the light might be insufficient for correct exposure on Automatic. The warning blinks last for approximately two seconds.
Open-Flash Button @
The red open-flash button is used to fire the speedlight manually without having to trip the camera's shutter. In this manner, you can create multiple-exposure "strobo- scopic" effects or paint the scene with light by firing the speedlight repeatedly with the camera set to "B" or "T." The open-flash button is also used in conjunction with the ready-light to determine if you can get the correct expo - sure when shooting on Automatic. This is especially useful when doing bounce flash. After setting up the shot, push the open-flash button. If the ready -light does not blink, you can take the picture. If it does blink, try moving the speedlight closer to the subject or bounce surface, or reset the Sensor Unit SU-2 to a color-coded position calling for a wider aperture.
