There are several advantages when using London life drawing models instead of photographs. First, you can see the model from all angles. This can help you draw with better realism as you can fully capture your subject.
Second, you can ask the model to pose in different ways. There is a time limit for the models but you can ask them to pose in various ways while they are engaged in the studio. You can make various studies based on these. That’s why it’s great for student artists.
Third, you can control external elements such as lighting, clothing, and props around the subject unlike a picture which is static. If you are aiming to use the model as a stand-in for a mythical character, a historical figure, and so on, then you can get fantastic results.
Fourth, there are lots of models to choose from. They fall into different body types, ethnicities, skin tones, hair colours, facial features, and other physical attributes. You are sure to find one that matches your ideal subject.
