  We present the analysis of photospheric emission for a set of hydrodynamic
simulations of long duration gamma-ray burst jets from massive compact stars.
The results are obtained by using the Monte Carlo Radiation Transfer code
(MCRaT) to simulate thermal photons scattering through the collimated outflows.
MCRaT allows us to study explicitly the time evolution of the photosphere
within the photospheric region, as well as the gradual decoupling of the photon
and matter counterparts of the jet. The results of the radiation transfer
simulations are also used to construct light curves and time resolved spectra
at various viewing angles, which are then used to make comparisons with
observed data, and outline the agreement and strain points between the
photospheric model and long duration gamma-ray burst observations. We find that
our fitted time resolved spectral Band $\beta$ parameters are in agreement with
observations, even though we do not consider the effects of non-thermal
particles. Finally, the results are found to be consistent with the Yonetoku
correlation, but bear some strain with the Amati correlation.
