And some have even come by way of modeling schools and model searches. For most, the next step is to contact several modeling agencies to see if one will represent you. You need to start getting test shoots. There are exceptions to this depending on the ramp, television, still photo etc. The modeling industry is big with many specialties.
Experience varies from model to model.
Hand models are often hard to find especially when you need one. Many models will have photogenic faces and good bodies but their hands and feet can be just horrid. Often times you will use one person for the face and have a hand model reaching into the picture to provide the hands. Of course the photographer makes it look like one person but in fact there are two. With jewellery photography we look for good hands, nice neck, and ears.
