We have experimentally investigated the affinity of streamers for dielectric surfaces using stroboscopic imaging and stereo photography. Affinity of streamers for dielectric surfaces was found to depend on a wide set of parameters, including pressure, voltage, dielectric material and discharge gap geometry. Our results show that higher relative permittivity, higher pressure, lower voltage, an d asymmetrical sample placement increase the chance of the streamer following the dielectric surface.
