Even though I've been into photography for over 40 years, a friend recently asked a question that I couldn't answer. I'm hoping someone here can assist. My friend has an old black & white photo of a home he recently purchased. The photo is from the 1930s. He would like to restore the house with it's original colors, but cannot determine the colors due to the bw photo. Is there any way to identify true colors from a B&W photo? Thanks in advance.
