I give you some advices.
For the best picture possible, you follow the next steps.
1- Don't use the camera flash.
2- Don't turn off all lights.
3- Turn on a little light, for example a lamp or a spotlight, but they are not very near. And the lights should be very faint.
4- Ensure that room or the place where you go to take the photo is a little lighting. No much and not few.
5- Use a "natural light option" in your camera (NOT Night mode). Disactivate the flash only.
Take the photo and you'll see that photo is very cool.
A very good option is to use the TV's light.
