here is the lighting setup i have used for the first picture in the last post. nothing special in particular but in case you would like to try it out, here it is.
i held the lamp behind the model's head manually with my arm and used a remote control to trigger the camera (the black shirt i wore completely blended into the background, i didn't even have to edit it out).
the second light was on the floor in front of the model facing away from her and was shining light onto a white canvas i used as a reflector to bounce soft light onto the model's face and to cause a reflection in her eyes.
the canvas was resting against a lightstand so it was semi-stable for the shoot.
try it out, have fun!
