Softboxes are wonderful tools for product photography. They allow you to get nice soft shadows, and beautiful edge highlights to make your product shine. But if don’t own them already, and all you plan to shoot are a few photos for eBay, it can get expensive. There’s light stands, flashes, the softboxes themselves, possibly reflectors and other doohickies.
This video from commercial photographer Leo Rosas shows a fantastic technique to create an “invisible softbox” using lightpainting techniques. Using a long LED tube, Leo recreates the look of a large softbox over his product, without actually having a softbox. It’s a very neat and versatile technique if you’re limited on gear.
