I wrote a question here

Now I need to know how to add custom categories for photos?


@jise - That would be a little out of scope for the help and support that we can provide to the community, but you could Google on how to create taxonomies for attachments -> , as that is what you would be looking to do here.

Once that is done you would need to figure a way to show them on the front end which could be done mostly by overriding the rtMedia templates ->
