eBay Junk photography
While I was in School, I made the majority of my income through selling junk on ebay. I would dig through thrift stores for used electronics and anything of value. It was miserable and addicting.
I would go to a place called Goodwill outlet where large tubs of garbage would be brought out in a warehouse. You would dig through the junk until hopefully finding something.
Nowadays Goodwill has goons to sort out anything remotely interesting from their stores, so making income from this isn't available anymore.
These portraits are what sold and are haunting documents of a rough period of my life.
