It's time to do some recon. You will need to take pictures of five objects, which you will do with your Binocucom. Press R3 to bring it out, then zoom in and out with the left analog stick. You want the reticule to turn green, which is when you can take the picture and have it count. Clicking L3 will bring up the objective marker, so use that if you ever get lost.
From where you start, you can take a photo of the guard with the armor walking back and forth in front of you. Get on top of the giant wall in front of you and get to a high spot, then take a picture of the Imperial Prison. Drop down below and head towards the Dragon Gate, taking a picture of it. Next, head towards Rioichi's restaurant and take a picture of the front entrance.
Bentley chimes in and says there's a commotion in front of the geisha house, so head over that way. Once you're in a good position, take a picture of the front entrance of the geisha house. El Jefe will now exit and Sly remarks that you should take a picture of him. Do so and after some dialogue, the job will be complete.
