Best way to make a separate light source for a chatacter?

Ck377

Allow me to use one of the images from the daz product for illustration purposes. In this image, the girl is in a dark environment, theoretically it is impossible for the girl's face to be so bright when the light source is only a candle, which means that the maker must have put in an additional light to brighten the girl's face.
That's what I'm asking, if the girl's face has a light that bright, why doesn't the door she's opening get brighter together with her face? In my experience if you place a glowing plane or spotlight in front of a girl's face, once you turn the light up, the illumination gets bigger. This means the flashlight effect.So Is there any way to make the light only illuminate the character herself in this darker environment with so many interactive items around her?

Canvasses, using Light path expressions, would do this - but so would adjusting the materials on the door to discourage it from taking light.

thanks for replying,the second way, you mean adjutst the translucency of texture,right?

what about the canvasses?can you show me how to do it?

The size of a spotlight, coupled with the "view angle" it is aligned at, and the spread-angle it has would also assist.

And Richard Haseltine's suggestion that the wood texture doesn't reflect much light is also assisting - if you look closely at the edge of the door the girl is holding you can see it is bright, compared to the face of the door; the wood-surface to the right of the girl is also lit.Notice also how bright her hand is, suggesting the "view angle" of the spotlight.

Postwork?

There're various ways as others mentioned. Mesh light with lower value of Spread Angle is commonly-used in the scene for such a requirement. And it'll be even better to have postwork on the render as barbult said. There'll be more potentials that you can make lots of dramatic effect and subtle change.

In the render above, you may tell the position of a mesh light from the reflection in the girl's left eye and the shadow around her nose wing on the right, as well as the candle stick. Well, if I were the author, I would 'darken' her right hand 'cause its brightness spoils the 'focus'...
