I will suggest you to help me as Archeologist by identifing the period of a picture that has been taken by a smartphone. The photo has no information of its time period.
It could be 2000 or 2020 for archeologist site. But more interesting i have a foto from 18xx which i need to color in real color. And i cant identify it exactly.
Compare and contrast them by their specifications and their actual lifespan of usage.Through this the readers may create a mind blowing idea and its sounds interesting, isn't right.
