For me, I've always used studio strobes as strobes, but Jaroslav Wieczorkiewicz over at AurumLight reminds us that if you have access to a studio strobe, you almost surely have instant access to another light source: the strobe modeling light.
Jaroslav uses three Einsteins heads to shoot this great portrait - Girl With The Broken Heart. This allows him to use a warm light coming from the modeling lamp, without gelling it. it also provides a different timing plane as continuous light has a lingering effect on the model rather than freezing it as a strobe. [Yup, so you get a whole new factor of creativity to play with]
