To paint one has to have some talent and certain skills and not everyone does, including me. To photograph the talent mostly rests on how you see things.
A photograph shows things as they are, albeit you decide how to frame the scene and how to show it. A painting is also how you see things but also heavily dependent in how you are able to transmit your vision onto a canvas etc.
Both mediums are similar yet different. It mostly depends on how you want others to "see" what you "see".
