I have been getting some requests lately for photo retouching, for clients who have old photos they want updated. This is not a service I have offered previously, but is one I am able to provide and happy to discuss. Do let me know if this is something I can help you with. Pricing is dependent on the specific needs of each client for each photo. Here are a couple examples of work I did for one client, who wanted to have individual portraits of herself and her husband, where previously none had existed. Scans were made from decades-old photographs (photographer unknown), which I retouched and reprinted.
