  A new picture is given of generalized parton distributions probed in
experiments in which the probe scale $Q^{2}$ and the momentum transfer
$\DD^{2}$ are well separated. Application of this picture to the $Q^{2}$
dependence of the form factors $F_{1}, F_{2}$ shows that gauge invariant quark
orbital angular momentum can be measured and indeed {\it localized} in the
transverse profile of the proton. A previous prediction that
$\sqrt{Q^{2}}F_{2}(Q^{2})/F_{1}(Q^{2}) \sim const. $ is generalized to GPD
language. This prediction appears to have been confirmed by recent CEBAF data.
