  Amplitude Analysis of two photon production of $\pi\pi$ and ${\overline K}K$,
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 $\sigma/f_0(500)$, $f_0(980)$ and
$f_2(1270)$ are determined from the residues of the resonance poles.
