I have two potential areas of expertise, one is vintage cars, and the other is old school photography, I did many things but finished up doing restorations of old colour and B&W photos, using digital techniques and traditional ones.
So I could testify about vintage of a particular photo or if has likely been altered, or whatever! Vintage cars, who knows what anyone would want me to say.
However I have had in mind an outfit I originally thought of a “School Marm” type. A grey pinstriped pencil skirt, about knee length, or an inch above, pantyhose of course. Then a matching jacket with a white blouse, silver wristwatch and bracelet, a simple black necklace, black heels. For hair, either my long sandy blonde tied back, or a shoulder length silver grey one.
I could answer, yes, indeed your Honour, I did indeed remove that woman’s husband from the photograph and substituted her new lover in his place, then recreated a vintage looking print on genuine B&W paper.
