There is a certain phenomenon occurring in some of the anime and cosplay circles that warrant a spin off subculture. This new subculture deals with Resin Ball-joined Dolls (known as BJDs) that are predominately made by Asian companies in Korea and Japan.

These aren't your little Barbie or GI Joe dolls that you had as a kid. These are serious dolls that are completely articulated, anatomically correct, and cost a few hundred dollars (upwards to a few thousand for the Limited Version) for a naked doll.
They stand anywhere from 5" to 16" tall, and often come with their own line of clothes, shoes, wigs, eyes, and other accessories. Their faces are hand-painted, and many face or body artists are sought after. There's even a sub market of home-grown enterpenuers who cater to the BJD owners by making custom clothes. No, these aren't meant for kids at all.
BJD owners often have several dolls (if they can afford it), and these
resin-kids get royally spoiled by their parent. And, it's not just females who own these dolls; there are a fair number of guys who also own their own BJDs (and no, they aren't gay).
Now, before you think these BJD owners are a little insane, consider other types of collectors...anyone who will spend a few hundred dollars for a rare coin, stamp, or other collectable goodie. These owners adore, care, love and really enjoy their resin kids. And, financially, these dolls can be worth quite a bit; with extreme limited editions reselling for a few hundred over their initial resale value...IF you can get a beloved owner to even part with their BJD.

But the BJD owners don't just keep their dolls in glass cases to look at on the shelf. These resin kids are taken to BJD meetups, parties, and other get togethers. They are handled very carefully, but they are 'played' with, lovingly, by their owners.

Now, what has this got to do with photography?
Since many of my friends have their own BJDs, I've gotten first hand looks at their resin kids, and frankly, they are often the most perfect model (as the name of this entry suggests). You don't need to worry about makeup, they come with their own wardrobe, and will stand still for you for minutes at a time without moving. Plus, they don't complain, and won't charge you for modeling time.
I haven't yet succumbed to purchasing a BJD (in spite of my friends trying), as I'm still working to get a lot of my own studio set up in order. So, in the meantime, I borrow a friend and their BJD for a day for their own photoshoot. Neither the friend or the BJD mind too much. :-)
