To use the photographs for a paid commission, the illustrator should look for photographs with the following Creative Commons licenses:
-
CC BY - This license allows others to distribute, remix, adapt, and build upon the work, even for commercial purposes, as long as they credit the creator.
-
CC0 - This license places no restrictions on the use of the work, allowing the illustrator to use the photographs without any need for attribution or permission.
CC-BY-ND (Creative Commons Attribution No Derivatives) would not be suitable in this case, as it does not allow adaptations or modifications of the work.
So, the correct answers are:
- CC BY
- CC0
