Looks like other street photographers (also named Eric) are shooting up-close and personal with a flash. Except the difference is that he is shooting with a medium-format Mamiya 7II and a large Metz flash. No idea how much it costs to develop all that film, but he makes fantastic photos and the process of him shooting in China is interesting as well. Make sure to watch these videos thoroughly to get a sense of his style which is very intimate, casual, and flows very well.
