We present a relativistic and cross-section factorized framework for computing nuclear transparencies extracted from A({gamma},{pi}N) reactions at intermediate energies. The proposed quantum mechanical model adopts a relativistic extension to the multiple-scattering Glauber approximation to account for the final state interactions of the ejected nucleon and pion. The theoretical predictions are compared against the experimental {sup 4}He({gamma},p{pi}{sup -}) data from the Thomas Jefferson National Accelerator Facility. For those data, our results show no conclusive evidence of the onset of mechanisms related to color transparency.
