I would like to buy photos for a story in our student magazine which has a circulation of 1000 copies. The photos are for editorial use only. The magazine is financed by sponsors and distributed and sold throughout Germany. And now my question is if I have to buy the Standard or the Plus license?
You are fine with a standard license. Your business model has no influence on this. It's only the print run (and digital print run equivalent) determinating the license type. If you use the pictures in an editorial way you will need, however, to quote the author and Adobe stock.
