Evolving Oil Painting

I would like to expand my photography taken into clear, detailed oil paintings ideally on canvas. The knowledge behind this is to expand my work into different mediums and to demonstrate my inspiration into a variety of outcomes with my main focus being the general public; revealing hidden treasures that would normally be missed without attention being drawn towards it. This practise would be feasible for me as I own a camera and resources such as printing ink and painting materials would be affordable. It is also quite clear that the larger the scale of work the more expensive it is going to be as more materials are going to be used and I would need to be aware of this when completing my study. I would like to develop my work by researching other portrait artists that are relevant to the work I am trying to portray at the time by visiting local exhibitions and using relevant research materials.
