For this kind of photography, i use two large black cardboards placed together with 90⁰ degrees angle each. One is used for the background and the other for the foreground. Tripod, camera in manual settings using the lowest aperture possible (i use 22), 100 iso and about 5-7sec for duration of the shot. Now the magic part (which is the most tricky part also) is to use a handlight (not a point source light) which you can use it for lightpainting the model. Using carefully the light, trying to avoid certain angles which make flares on the model, you pass the light over your model during the time of shot. This way you make unique photos. Every photo is different from the other as you and only you define the light source over the model with your hand. It's your own unique light signature.
You can always use stable light sources in angles you define (this has a popular use among photographers). In this way you have more control of your light but it's way more difficult to create those bright light lines that follow the shape of your model. On the other hand if you don't care for those lines, then use stable light sources with difuser in front. The best way to difuse your light is using a photobox but then you'll need strong light sources.(at least three of them)
The first technique can be done with less than 10E, the second one, with more than 100E. The first technique is for creating only this kind of photos you see in these posts, the second one is for product photography. In my collection thread you can see photos using both techniques.
I hope i helped and not confused you more.🙄😁
