If you're serious about selling on eBay, get serious about photography. It's a good idea to set up an informal photo studio in a corner of your home office or warehouse where you can shoot good pictures anytime. You'll need:
Stage: Floor space or a tabletop where you can set up your item
Background: A neutral-colored backdrop made of cloth or photo paper
Lights: Simple lighting such as clamp lights, track lights or household lamps
