Statistically improved data of total cross sections and of angular distributions for differential cross sections and hyperon recoil polarizations of the reactions {gamma}p{yields}K{sup +}{lambda} and {gamma}p{yields}K{sup +}{sigma}{sup 0} have been collected with the SAPHIR detector at photon energies between threshold and 2.0 GeV. Here total cross section data up to 1.5 GeV are presented. The opposite sign of {lambda} and {sigma} polarization and the change of sign between forward and backward direction could be confirmed by higher statistics. A steep threshold behaviour of the K{sup +}{lambda} total cross section is observed.
