"None of this revenue is coming back to the original artists," explained Overlai founder Luke Neumann in a blog post about his new mobile app which aims to protect photography in the age of AI.

Neumann, who also signed the letter, launched the free app Overlai with world-renowned photographers Paul Nicklen and Cristina Mittermeier, when they noticed text-to-image generators could easily replicate the unique styles of both photographers. And, Neumann stresses the amount of work that goes into conservationist photography - the cost of travel and spending weeks, sometimes months in a location documenting a delicate ecosystem.
