Low Q{sup 2} photon-proton cross sections are analyzed using a simple, QCD-motivated parametrization {sigma}{sub {gamma}{sup {star}}p}{proportional_to}1/(Q{sup 2}+Q{sub 0}{sup 2}) which gives a good description of the data. The Q{sup 2} dependence of the {gamma}{sup {star}}p cross section is discussed in terms of the partonic transverse momenta of the hadronic state into which the photon fluctuates. {copyright} {ital 1998} {ital The American Physical Society}
