I recently completed the Shutternut skill challenge (complete 5 photography collections) and got a popup message which included this:

"Also, a Bonus section has been added to the Photography Skill Journal with each subject worth a lot of cash and ancient coins."

I can't find any bonus section, and I can't find any reference to it on the web.

What is this about?

hitting J brings up the skill journal but thats about as much as I know, photography skill makes 0 sense to me
