Determination of intrinsic shapes of individual elliptical galaxies using photometry is an important problem because the number of galaxies with good photometry is many more than those with good kinematics. We determine the intrinsic shapes and prior density which is called as flat prior reported by Chakraborty et al. (2008) and Singh & Chakraborty (2009). Our results are presented as plots showing the intrinsic shapes of the galaxies as a function of (q0, q) for 2 and (q0, q, |Td|) for 3 dimensional shapes, where q0 and q(= q) are the short to long axial ratios at small and at large radii and |Td| is the absolute value of the triaxiality difference, defined as |Td| = |T - T0| . The probability is shown in grey scale: darker is the region higher is the probability.
