To take a selfie, you need to find a maniac. If no maniac wants to be photographed with you, then you will have to make friends.

I'll tell you on the example of Wesker:
1. Find a maniac who will understand what you want. It's almost impossible, but I found it. I'm not so sure about you, so we're looking for a friend. One is enough.
2. We ask our pie buddy if he has a Wesker (the maniac you need), if not, then we stop being friends with him and add him to the blacklist .
3. Go to "my game" and take the pharmacy. You need your friend to hit you. Then you will be able to enter it...
4. So, while you are in your friend, you need to heal.
5. Now you have to look in the same direction with him. Press "1" or "2" to make your character turn his head straight and you can take a screenshot.
Most likely you will get something like this:

If you want a closer screenshot, then you need to find some angle. Then the frame will be closer, like this one:

IF YOU HAVE MORE THAN ONE FRIEND
Then just ask him to take pictures, for this he must be standing behind you. And you just look ahead.
NOTES: not all maniacs can approach because of their height, let's say you want to take a picture of Meg Thomas and Michael Myers, but Meg is shorter than Michael. Therefore, it is unlikely that you will succeed. The same problem with Wesker, he is taller than Meg Thomas. Therefore, in order to take a picture of Meg and Wesker, it is necessary that Wesker use his strength and sit down a little. on the bottle While Wesker will grin. Another situation, you want to take a picture of Chris and Wesker, Chris is taller than Meg and shorter than Wesker (as in the original, though much lower in DBD), so you will get a photo, but Wesker will not grin. At most he can chuckle. If you use the ability, then Wesker may be slightly lower than Chris and the photo will not work.
So try it!
By the way, something else, because of Wesker's ability, a light smoke may appear distorting your faces, so you will have to catch the timing.

• IF A MANIAC IS TALLER THAN YOU: such maniacs as Nemesis, Michael Myers, the Doctor are tall, taller than Chris Redfield (only in the DBD world). You can take a picture with them only by using some kind of elevation: stairs, texture irregularities, some books or firewood that are on some maps.
  
• IF THE PHOTO IS TOO DARK: Many cards in DBD have dark lighting and your photos may come out dark. Take light cards or cards with houses, for example, there are many houses on the Haddonfield map. In a blue two-storey house, there is a chest of drawers with a table lamp. This is the photo you will get, you can still try to add brightness and saturation, if you play with filters, then you should not have any problems. Also, if your third friend is taking pictures of you, then you don't need to look for an angle and you can take pictures almost everywhere.
  
  
• You took a photo, but the red glow of the maniac interferes? Use the skill "Insidious".
  
  
• Some maniacs may use their ability to hide the red glow or to pass through you. For example, Michael Myers or Ghost Face. By the way, GF is sitting lower than Chris Redfield, GF is sitting the same height as Meg Thomas, but if you press "1" or "2" while sitting down, you will become taller than him, so you need to be photographed while sitting with the help of another friend.
  
• If you ask another friend for help, then I warn you, sometimes it may look like this:
  
  
• Here is an example of the difference in height. Meg is in shock...maybe she's going to pass out from the splendor of Wesker.
  

Wow, you still have friends...I envy.
We need to capture this in a photo, so we do almost the same thing.
Looking for a corner. We leave our friend in the corner to think about his behavior, because he still hasn't bought himself a Wesker. We ask the maniac to hit you and run into his friend, get treated. Okay, now you're inside your friend...Your relationship is developing fast, right?
Now your friend can just look ahead, and you press "1" or "2". Done.
If you have even more friends [punch] I don't believe it, dude![/strike], then you can ask one of them to take a picture of the two of you. Just like in the maniac version, your photographer should be standing behind you. Don't be afraid of photo shoots, the photographer will tell you how to turn your head or body.
Be careful, you will have to catch the timing, because some survivors like to sleep. And no, I'm not talking about Quentin.

Symbols in the table: "+" - the photo can be taken without any problems; T - additional efforts are required for the photo, for example: textures to correct the difference in height
Note: *Legion, you can also use the legion's state in the ability. *Demogorgon, Oni can be photographed when these maniacs are in the ability. *Artist, Dredge has not typical heads with elongated necks. *Mastermind it was described above that you need to use the ability.

Thanks for taking the time to do this sh*t guide.
