    Abstract:
    We discuss the photon motion in the framework of general relativity
    coupled to non-linear electrodynamics. Photons no longer follow the
    null-geodesics of the spacetime but rather null-geodesics of associated
    effective metric. Here we compare structure of circular geodesics and
    time-delays of neutrinos in Bardeen spacetimes with those of photons in
    effective geometry. We also discuss construction the Keplerian disks
    images in the Bardeen spacetimes and compare them with the images of
    Keplerian disks in RN spacetime.
