Go to the marker in the central part of Waterfront. Interact with it to connect to your inFamous Paper Trail profile. If you have performed all of the steps, on the internet page, properly (entering both combinations, basing on the analysis of the picture with the labyrinth) you will be allowed to start the seventeenth mission and it is going to concern taking photos in five different locations, all around the city. Press UP on the D-Pad to start the mission.
You can visit the locations, in which you take the photos, in any order but, to maintain some order, go to the point located in the North-Eastern part of Rainier. After you get there, stand in the marked spot and select the camera. The trace left by Celia has been shown in the above screenshot and you need to photograph it.
Now, head towards the marker in the Northern part of Rainier. The trace that you are looking for has been shown in the above screenshot.
Go now to the South-East and reach the marker in the central part of Rainier. Locate the next trace shown in the above screenshot.
Go now to the Western part of Rainier. The trace is in the spot shown in the above screenshot.
Finally, examine the marker located in the Southern Rainier. You will find the trace in the spot shown in the above screenshot. Return to the starting point for this mission to send the photos. You can now turn off the game and start completing the puzzles on the inFamous Paper Trail page.
