  We present a unified description of elastic and transition form factors
involving the nucleon and its resonances; in particular, the $N(1440)$,
$\Delta(1232)$ and $\Delta(1600)$. We compare predictions made using a
framework built upon a Faddeev equation kernel and interaction vertices that
possess QCD-kindred momentum dependence with results obtained using a
confining, symmetry-preserving treatment of a vector$\,\otimes\,$vector
contact-interaction in a widely-used leading-order (rainbow-ladder) truncation
of QCD's Dyson-Schwinger equations. This comparison explains that the
contact-interaction framework produces hard form factors, curtails some quark
orbital angular momentum correlations within a baryon, and suppresses two-loop
diagrams in the elastic and transition electromagnetic currents. Such defects
are rectified in our QCD-kindred framework and, by contrasting the results
obtained for the same observables in both theoretical schemes, shows those
objects which are most sensitive to the momentum dependence of elementary
quantities in QCD.
