B&W to color. Hand coloring used to be done with transparent oil, back in the day my mom used to hand color prints for my dad, I even tried my hand on a few while at the Ohio Institute of Photography (still have the oils somewhere, ha). Luckily this old print was in almost perfect condition, very little repair of torn and damaged areas required.
Total repair and restoration of print damage,
missing areas, and color contamination/fade
This client was told by a local professional it could not be fixed, I laughed
and thanked them for letting me try…
