We study the photoproduction of scalar mesons close to the threshold of
f_0(980) and a_0(980) using a unitary chiral model. Peaks for both resonances
show up in the invariant mass distributions of pairs of pseudoscalar mesons. A
discussion is made on the photoproduction of these resonances in nuclei, which
can shed light on their nature, a subject of continuous debate.
