The first step to a campaign is to decide the concept. This will depend on the collection, season and demographic.
The mood board is a collection of images that solidify the concept and give the photoshoot legs to stand on. This will include colors, locations, style of makeup and hair, and anything that will help visualize what the final photos would look like.
The budget includes everything from studio rentals, props, fees for all vendors like makeup artists.
The photoshoot generally starts with the mood board and takes a life of its own.
The editing and skin retouching time would vary depending on the concept. Generally, a two hour shoot takes about two weeks to edit.
