Neutrinos are almost massless, travel close to the speed of light, and pass through matter almost undisturbed. Photons, on the other hand, have no mass, travel at the speed of light, yet are absorbed and/or reflected even by fairly sparse matter such as gasses.
A photon has an electromagnetic field (really, photons are electromagnetic fields) that can interact with charged particles - a neutrino has no charge and so unless it hits something head-on doesn't interact
