Look at this photograph of a Ming vase. It is made out of kaolin clay, a material first used during the Ming dynasty. What is special about kaolin clay?

Photography has changed its subject matter quite a lot over the past few years. in the 1800's, it was considered normal for families to have  post mortem photos of their loved ones, and now that would be completely unacceptable. i think that photographers have always pushed boundaries and have been eager to capture everything, it is just society that changes their boundaries.

Ill have to say false. hope this
