You may select any of the above types and go for the course. Further, you can work as a freelancer.

Hi Divya,
Photography is more of a profession than a career. Thought to be a not-so-good job in the late 60s, photography has now turned out to be one of the most sought after professions in India.
Salary:
Photography as a field has no particular or fixed career and salary structure. One has to be very brave to start off as a freelancer. You would rather begin by working in a studio. One can start as an assistant to senior photographers in which you'd be paid Rs 3500 to Rs 6000. Once you are established, you would be paid as per the assignment. The range can be from Rs 10,000 to Rs 30,000. Fields like commercial photography pay higher compared to the other fields. Beginnings can be made at Rs. 15,000 which may grow over a period of time.
Eligibility: You can start right after you finish with your schooling [10+2] or you can take up photography after your graduation in any subject.
