This work presents a simple method to determine the significant partial wavecontributions to experimentally determined observables in pseudoscalar mesonphotoproduction. First, fits to angular distributions are presented and themaximum orbital angular momentum $\text{L}_{\mathrm{max}}$ needed to achieve agood fit is determined. Then, recent polarization measurements for $\gamma p\rightarrow \pi^{0} p$ from ELSA, GRAAL, JLab and MAMI are investigatedaccording to the proposed method. This method allows us to project high-spinpartial wave contributions to any observable as long as the measurement has thenecessary statistical accuracy. We show, that high precision and large angularcoverage in the polarization data are needed in order to be sensitive tohigh-spin resonance-states and thereby also for the finding of small resonancecontributions. This task can be achieved via interference of these resonanceswith the well-known states. For the channel $\gamma p \rightarrow \pi^{0} p$,those are the $N(1680)\frac{5}{2}^{+}$ and $\Delta(1950)\frac{7}{2}^{+}$,contributing to the $F$-waves.
