In the case of the traditional standard disk with an inner radius of 3rg (three Schwarzschild radii) around the Schwarzschild black hole, there appears to be a dark central shadow with a radius of about 3rg. In the case of a disk extending down to 1 rg, on the other hand, we found that the radius of the dark shadow is about 2rg. These shadow sizes are different from that obtained by Falcke et al. (2000, AAA 073.155.002), where the shadow radius is about 2.6rg. This is because they considered an optically-thin spherical envelope, while we assumed an optically-thick luminous disk. In addition, we found that in an edge-on view the central shadow becomes a semicircle due to the projection effect. Such a silhouette of a dressed black hole throws light on the space-time structure of the hole as well as the type of surrounding disk.
