First it was physical currency that was digitized, now even physical objects have joined the the digital boy band. I have come to know how NFT's they work, how to create them and eventually sell them, now that's my ultimate goal.
It's still a process, but I've gained so much interest that I decided to be all hands on deck. One thing. I'm aware of is that you have to be original in all aspects, otherwise your creative work, qualifies as a fake.
Photos or image you produce must be your own work, not copycatting. When it comes to people's photographs especially, you most probably must get a consent from the said individual before using their photos as your creative work, for publishing purposes.
