Copyright, a form of intellectual property law, protects original works of authorship including literary, dramatic, musical, and artistic works, such as poetry, novels, movies, songs, computer software, and architecture.
A serious perk of copyright is that gives the creator of an original work complete control over its use and distribution. Photographs are protected under copyright law as artistic work under Section 2 (c) of Copyright Act 1957 in India. Photographs are protected under the law of Copyright as it has been included as an artistic work.
Therefore, you need an authorization from the original author in order to use it for your own benefit.
But under the principle of fair use, use of photographs without prior consent of the photographer is permissible if the person using it does not have any malafide intention of attaining undue profits from it. Ex: Teaching/research purposes, legislative purposes, judicial proceedings.
Hope this answers your query.
