Before so-called radiometric dating, Earth's age was anybody's guess.Our planet was pegged at a youthful few thousand years old by Bible readers (by counting all the "begats" since Adam) as late as the end of the 19th century, with physicist Lord Kelvin providing another nascent estimate of 100 million years.This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.
Old photographs are full of clues that can help you to do this, such as clothes or hairstyles, and we have a list of useful contacts and resources that may be able to help you date your photographs by fashion.
But even without these pointers, it is possible to date a photograph by its type, rather than what it depicts.
Many archaeological chronologies, including that of the Hohokam in southern Arizona, are based on a series of radiocarbon dates on wood.
This paper argues that because of variability in rates of wood decay processes (in the environment and in systemic context), such archaeological chronologies are potentially biased towards excessive antiquity by an old wood problem and must be reassessed.
Over the next few weeks, I’ll be showing you how to date your old family photographs by format and process, using the photographic techniques that dominated the first 100 years of commercial photography.
