Bounce Cards
Many models include have a built-in bounce card next to the pop-out diffuser. This can be used to bounce a small portion of light forward to provide catchlights in the eyes of your subjects.
This feature is available on both Pentax FGZ models, the AF Metz models from the 44 AF-1 up, and on the new Sigma 610-series flashes (but not on the older Sigma 530 series).
Note that some variants of the Tumax DPT3 series have this feature, but earlier ones do not.
