Amplitude Analysis of two photon production of ππ and K¯K, using S-matrix constraints and fitting all available data, including the latest precision results from Belle, yields a single partial wave solution up to 1.4 GeV. The two photon couplings of the σ/f₀(500), f₀(980) and f₂(1270) are determined from the residues of the resonance poles.
