There are many ways to pose female models lying down. Different poses, even if the model is lying down in many ways, can change the emotion being portrayed by the model so try out these poses for various effects and to try for a natural photo. Experiment with these poses for a distinctive picture.
Before beginning to pose the model, try to let her relax. Take several pictures in poses that are simple and put the model at ease or talk to her about what kind of shots she would like to have.
To portray a youthful image, have the model lie on her stomach with her feet up. Have the model swing her feet in the air or tell her a joke to get shots of natural smiles and laughter. Lie on the ground in front of the model for the best shot or place the model facing upwards on a slight hill with the photographer elevated above the model.
To produce a more serious photo with the model still lying on her stomach, have her rearrange her arms and legs and change the expression on her face. Place the arms closer together and the hands near her face. Instead of swinging the legs, have the model hold her feet together and give the photographer a small smile. These subtle changes in the pose can give similar poses a distinct feel.
A female model can be placed on her side for a more relaxed image. Have the model lie on whichever side is most comfortable for her with one hand holding her head up. The other hand can either be positioned in front of her body or can lie along her body. This pose is also a great way to use props, whether in front of the model, or the prop they are lying on.
For a more alluring image have the model lie on her back and look to the side. The photographer should be slightly above the model. Take different shots with the arms up or down and looking both ways until the desired effect is created.
Let the model create new poses. Try to take pictures on an overcast day when there are the least shadows.
