What is the white reflective material which so often appears in stock images, and where can it be purchased? 

Thanks,
Steve

Greetings.  I'm new to microstock.  I'm not trying to change the world, get rich, or quit my day job.  I just want to earn a little extra dough doing what I love to do. 

I've been shooting images for stock and uploading them for only about a month at this point, so I don't know much about the current market.  I'll just say that it's a bit overwhelming seeing page after page after page images similar to those you've just uploaded, and realizing that you're at the end of the line waiting to get on the ride.

I'm just wondering if there's any space left for even a modicum of success. 

Thanks for your thoughts and knowledge.
Steve
