Go to Behind the Scenes > Default Settings, and scroll down to Default Image Licensing Prices (for sale on Licensing.Pixels.com), or alternatively (other info there) Behind the Scenes > Image Licence Program (on the bottom).
There you'll find a lot licencing information. However, nothing about pricing, meaning how to set competitive prices. And this is actually really a problem. It doesn't matter where you look in the Internet, Getty Images, Google, Youtube, etc. - there is nowhere any reliable information.
What I did (but it's still in the research phase) is to activate my network and ask people to ask around if they know anybody who is actually working in the media business, e.g. purchasing images online. So far, there have 2 names popped up but those people have not yet volunteered information.
Therefore, should there be anybody here who knows something about the buyers market for licencing, please share your knowledge!
In vain have you acquired knowledge if you have not imparted it to others. Deuteronomy Rabbah (c.900)
