Here are some samples from the great collection of photos from London based photographer Mark – and the very beautiful model Imogen. Mark concentrate on working with few models, and photograph them over time. It’s almost as you can see Imogens different moods in the photos – happy, sad, thoughtful and sensual – and always beautiful and natural. I think you can see the good chemistry between the photographer and the model results in wonderful pictures. You can see more of Mark’s work at his Flickr website here.
