Photon spheres play a pivotal role in the imaging of luminous objects nearblack holes. In this paper, we examine observational appearances of a starfreely falling in hairy black holes, which can possess one or two photonspheres outside the event horizon. When there exists a single photon sphere,the total luminosity measured by distant observers decreases exponentially withtime at late times. Due to successive arrivals of photons orbiting around thephoton sphere different times, a specific observer would see a series of lightflashes with decreasing intensity, which share a similar frequency content.Whereas in the case with two photon spheres, photons temporarily trappedbetween the photon spheres can cause a peak of the total luminosity, which isfollowed by a slow exponential decay, at late times. In addition, these photonslead to one more series of light flashes seen by the specific observer.
