Trace developer for papillary crests. The developer is made up of a base product, different thickness, sieved iron ferrija (from 0.45mm to clean powder) and organic and inorganic pigment, either variants of titanium, black ivory or black smoke etc. depending on the specific characteristics of the support where the trace to be developed is. The developer is applied with magnetic paintbrush in the support's surface, the trace with its papillary crests appear to be lit so that they can be photographed. If it is necessary to boost the trace and papillary crests, the trace is cleaned, or 'combed' using the magnetic paintbrush and base product made up of ferrija without any pigmentation. |
