Measurement of the Low-x Behaviour of the                        
                      Photon Structure Function                                
  
 Deep inelastic electron-photon scattering has been studied using              
 data taken by the OPAL detector at centre-of-mass energies of                 
 91 to 189 GeV, exploring the photon structure function in Q^2 ranges          
 of 1.5 to 30 GeV^2 (LEP1), and 6 to 30 GeV^2 (LEP2), probing the              
 lowest x attainable. The latest Monte Carlos and new methods,                 
 such as multi-variable unfolding, have been explored to reduce model          
 dependent systematic errors on the structure function.
