Dark Cloud 2

Story related and cannot be missed. After you receive the camera from Cedric, you will be tasked with taking pictures of a belt, a milk can, and a pipe. Set the camera as an active item. While walking around, press to bring up the camera. Press again to take a picture. Once you have taken the pictures of what you need, press and go down to the "Make" menu. Select "New Invention" and select the three pictures with the button. Hit and confirm the invention. Congratulations, you've made your first invention and the trophy is yours!
