Copyright protects original photographs. Unlike patents, trademarks and designs, the rights associated with copyright rest in the author of a work once the work is created in a material form. It allows an original work to be considered a property that is owned by someone. No official form of copyright registration is necessary for photographs. All photographs are protected by copyright from the moment it is taken and saved in some format. All you need to do is prove that you are the photographer and that you own the copyright of that particular work. To prove this we suggest the following:

Present a copyright notice (stating that the work is protected under law)
a copyright notice is not required, but displaying it shows that you are aware of copyright law.

Keep supporting evidence.
The progression of the work. Early drafts, sketches, synopsis, rough recordings, etc. are all evidence that the work progressed over time, rather than being copied from elsewhere. Footprints or watermark evidence inserted into finished documents that will identify the author in some way, such as deliberate mistakes or watermarked logos.

Ensure your photographs are properly marked and dated.
Some people might even post or courier their own work to themselves, to record the date of creation.

Copyright Duration
