Within an isospin- and momentum-dependent Boltzmann-Uehling-Uhlenbeck (IBUU)transport model, we investigate the hard photons emission from neutron-protonbremsstrahlung in reaction system of $^{208}Pb+^{208}Pb$ around Fermi energy.Effects of neutron skins in coordinate ($r$) space and proton skins in momentum($k$) space on the time evolution, the angular distribution, and the transversemomentum spectra of hard photons with different energies are studied. It isshown that the emission of direct hard photons is sensitive to the neutronskin, which has larger effects for more energetic hard photons. Meanwhile, wefind that the proton skins have an important influence on the emission ofdirect hard photons, and its effect is actually even larger than that ofneutron skins. It needs to take the effect of proton skins into account when wedetermine the size of neutron skins by comparing transport mode predictions ofhard photons with the corresponding experiment measurements.
