From the data of Fermilab polarization experiment E704 the analyzing power $A^{\gamma}_{N}$ of inclusively produced photons was extracted. It is small, of order $2$ to $4\%$. The analyzing power of ``leading" photons (fastest in $\pi^0\to \gamma\gamma$ decay) is twice higher than $A^{\gamma}_{N}$. The Monte Carlo simulation is performed in order to see effects at higher statistics than in E704 experiment. This simulation showed that photons may be used as a basis for future polarimetry at polarized colliders.
