  We use the recently discovered simple photometric parameter Central Intensity
Ratio (CIR, Aswathy & Ravikumar 2018) determined for a sample of 57 nearby (z <
0.02) Seyfert galaxies to explore the central features of galaxies and their
possible connection with galaxy evolution. The sample of galaxies shows strong
anti-correlation between CIR and mass of their central supermassive black holes
(SMBH). The SMBH masses of ellipticals are systematically higher for a given
CIR value than that for lenticulars and spirals in the sample. However, the
correlation between CIR and central velocity dispersion is weak. CIR appears
less influenced by the excess flux produced by the central engine in these
galaxies, when compared to spectroscopic parameters like velocity dispersion
and OIV flux, and proves a fast and reliable tool for estimating central SMBH
mass.
