Have you want to take a picture of your character when designing, even when you want to showcase them in your project? Unfortunately in the original game without mods. There's no built-in screenshot you can do that. You can only use the weapon camera to take a picture of your character, however, this proven cumbersome on most of the designers. But that doesn't matter, this guide will simply help you how can you take screenshots in-game fast without the use of the camera weapon.

GUIDE #1
There is a mod called "Amazing Screenshot" made by Silent. Be sure to read all the description, including on how to activate it so you can able to use it properly.

GUIDE #2
After mastering the use of Amazing Screenshot mod, it's time for you to take some awesome screenshot for your characters. To do this, select any actor you want and take a screenshot on their faces or their body. Make sure you've turn ON the "Store Gallery Photos" in-game to save all your screenshots.

You can optionally take screenshots on anything like the environment, atmosphere or something better. Most designers are doing this to create their own headers which they display it on GTAForums topic. That's all and have fun.
