The Dark Pictures Anthology: The Devil in Me

#Edit1 - I also believe you are able to use this method while playing the online mode (But need to pick Mark in character selecting). But I can not confirm 100% because did not play Devil in me with anyone, but this worked for me in Man of medan

My guide is for people who owns the Curator´s Cut (DLC), this DLC is free for everyone who pre-ordered the game (If you bought the game as me in official Bandai Namco store press "view" in your order details and then "show the key" or something like that, but far as I know every shop has to send you the code if you pre-ordered the game). If you did not pre-order the game, and want to use my guide (I know, you propably will not) you have to wait until DLC becomes free as the others TDP Curator´s Cuts.

Solution:
As soon as you beat the game once, you will unlock Curator´s Cut (new game, select difficulty and choose Curator´s Cut). You need to complete the prologue, you can skip Curator's intro, and need to watch character presentation. Finally you will reach this moment when the crew is waiting for the ferry, you will play as Mark in this moment, so just press and take photo of each (4) crew member (square in photo mode will be green when you aim on character, next press ), easy as that

Please do not dislike this guide only because you do not own Curator´s Cut, I do not know yet how to obtain the achievement in standard game mode because in my case Mark never was playable with Jamie.

Good luck hunters!

In Theatrical Cut you can take photo of:

1. Kate during the Scouting scene,
2. Jamie as her Mannequin during the Mannequins scene,
3. Erin and Charlie during the Lighthouse scene.

Note: The second one was a bit buggy because the green sign disappeared very fast.

Far and away the easiest spot to get this achievement is when you get dropped off in the limo before making your way up to the lighthouse. You have all characters there so as long as you are in control of Mark you can go round each one taking a photo of them and the achievement pops after the last one. No hassle at all.
