We present a model based on a dipole picture with a hard and a soft Pomeron in which large dipoles couple to the soft Pomeron and small dipoles couple to the hard Pomeron. The parameters in the model are fixed by proton-proton scattering and the proton structure function F2(x,Q2). The model is then applied successfully to the proton charm structure function F2c(x,Q2), the proton longitudinal structure function F2L(x,Q2), J/\ensuremathψ photoproduction, deep virtual Compton scattering \ensuremathγ*p\ensuremath→\ensuremathγp, the real photon-proton total cross section \ensuremathσ_\ensuremathγptot(s), the real photon-photon total cross section \ensuremathσ_\ensuremathγ\ensuremathγtot(s), and the photon structure function F2^\ensuremathγ(x,Q2). Differences between our predictions and data on charm production in real photon-photon interactions and the \ensuremathγ*\ensuremathγ* cross section \ensuremathσ_\ensuremathγ\ensuremathγtot(s) are discussed.
