The typical features of the photocouplings of the 70 L=1 and 56 L = 2 baryon resonances are discussed in view of the recently reported experimental data. It is emphasized that our relativistic quark model is very convenient for the phenomenological study on the. photo-couplings and also is suitable for a simple physical interpretation. The phenomenological analysis of the photocoupling data based on our model concludes that the transition from the quark state (j^P=1/2^+, λ=1/2) to (j=L+1/2, λ=3/2) is dominant in the photo-transitions from nucleons to the excited baryons in both cases L=1 and 2. Our result implies the non-negligible magnitude of the value of ΔL_z=2 term. The experimental data on A^p_<1/2>(P_<13gt:) and A^p_<3/2>(P_<13gt:) is crucial to confirm the strength of ΔL_z=2 term.
