Photography is an enjoyable hobby that could be an exciting career. In photography, it is possible to learn very easily how to take really excellent photos with a tiny bit of help. The easiest way to test out your skill is by trying out something totally new. You could try necromancer themed photography.
Still-life photography of book and skull could be a good start along this theme. You don’t have to use an actual skull for this photography, there are synthetic ones for this purpose. You could even use skull shaped wood or metal for this photography.
