if anybody can help me with lighting and settings to get something like the image. Thanks
First, make the world background black, then add a single light because in your image there is no light whatsoever in the shadows.
The position of the light will depend on the type you will use, e.g., for a sun lamp the position doesn't matter. Approximate orientation can be determined by examining the shadows and highlights on the chin and hair regions. See in this picture how the shadow around the chin (relatively smoothly curving surface) is left of the center of his chin and the highlights in his hair extend to the right of the midline through his face.
In this case, I used a single area lamp with a size of 1. You can see that with the more finely detailed model due to texturing, the lighting looks better than in the next example because of the finer shadows.
In this case, I used a sun lamp, but of course, you could also use a spot, point, area, or even a mesh light.
- You can adjust the lamp size to change the how blurred or scattered the shadows are.
- If you want any ambient light to show on your object (which is not in your picture), you can change the strength of the world background based on if a ray is coming from the camera.
- If you want more photorealistic light behavior, get Filmic.
Keeping in mind that light travels in a straight line. If you study the shadows there are clues as to how to recreate the lighting.
In the reference image the shadows are black = One light source. The angle of the shadows reveal the light is slightly up and to the back of the subject. The shadow edges are hard which means the light source is either a spot light or small.
EDIT: A little more on light source relative to shadows.There are two major factors in the light source that effect the resulting shadow. It's size and distance from the subject. Light sources that are smaller and/or further away yield a shadow with a "harder" edge. Conversely, light sources that are larger and/or closer to the subject yield "softer" shadow edges.
