Senior fashion photographers with a good track record and those who have consistently produced great work shoot big campaigns for brands, both domestic and international. Their work also involves a lot of travelling given the nature of the work. They also shoot a lot of portrait-based campaigns and beauty campaigns. For this, one needs to have an understanding and develop a keen sensibility of the subject. Budding fashion photographers shoot a lot with younger fashion designers.
During the initial part of his career, a fashion photographer gets to work a lot on look books and catalogues. The better ones end up shooting campaigns for designers, which help a great deal in portfolio building. The best way to get ahead is to assist a senior photographer for some time.
