In Mexico Jacobson borrowed a
Rolleiflex camera and taught herself how to take and develop photographs, using how-to books as a source of instruction. The bulk of her 14,000 negatives represented photos of everyday life, providing details of the business and religious practices of local people, taken in the marketplace and along its narrow streets, and also individuals and landscapes. Jacobson's archive of negatives was described in 2009 as destined for
Casa Na Bolom, a museum in San Cristóbal. ==Death==
