Referencing licensed image on poster

[default8yf10v0q4t1o]

Hi. I licensed an image on adobe stock. I want to use it on a poster. How do I reference the image? I'm not familar with copyright rules. 

Do I put a copyright logo on the image with the copyright owners name? Do I add "permission obtained"?

I want to copyright the rest of my poster myself but the photo's are obviously not mine, I only licensed them. 

How do I copyright the poster, but make sure I give the appropriate reference to the licensed adobe photo?

Help!

You need to credit assets it used in an editorial sense. It is fully described in the licensing terms how to correctly credit. Posters are no use in an editorial sense and do not need to be credited (you can, however, credit if you want).

(Disclaimer: As always with licensing, this is my interpretation of the rules. I think they are correct and advice is based on reading and interpreting the licence terms and on fair use for both the buyer and the artist/stock company, but I cannot rule out that my interpretation is wrong. I'm not an Adobe employee).
