Although Mikatan's photos are pretty much all alike, I always like the shots she takes in her previews. The simple setup in front of her computer, with office lighting, does a fine enough job highlighting the figure she's showing off. This time Mikatan has a post about the process. It's really pretty inspired in its minimalism.

She shoots with a "borrowed" Sony Alpha 350. It's supported by her knee because she's too lazy to use a tripod. The lighting is done by holding cardboard over the figure, casting a shadow to give it some depth. Easy but effective!

The post also discusses Nendoroid joints. I've never had a problem with them, like, conceptually, but maybe if your spatial reasoning isn't on my level then it's worth a read.
