Photography is one of the most popular tags on here so it is not surprising the results you are having. It is always a genre that is tailor-made for the blockchain.
Photographers are the epitome of content creators yet had a very tough time monetizing their work. Many had to do things such as shooting weddings and such to earn a living. Just snapping a few high quality photos netted very little. Once in a while some payment would come in off a site that business used for marketing purposes, but that was rare.
It is terrific that you are getting more exposure for these people and rewarding them for great content.
