So far I still don't have the slightest idea what they would normally pay.
Are sites like
www.alamy.com reliable for calculating the license fees? According to that site, 3 consumer magazine inserts, full page, 500,000 print run, costs £ 1330. But I would be producing 5 ads like this, and the usage is probably more than that, but doesn't £ 6650 just for the license seem excessive?
Then I tried Getty Images. The price for one image, UK, 1 year, general advertising use, is £5,500. Wow, multiply that by 5 and you get £27,500.
These prices are so far apart that I am still feeling confused. Surely there is an industry-accepted calculation out there?
