RGB Memories (2015)

Looking at the digital scans of old photos of places I have lived in, on the laptop monitor, I wonder if I could return to the time and location to take photo, what would I have chosen to shoot. When I started to take photos on basis of the original ones, however, I came across the subject that I have always been wondering. Are the images able to represent the reality? or is the reality just a harmonic association of three colors of red green and blue ?
