Also, I read Read This if you Want to be Instagram Famous, by Laurence King Publishing, featuring contributions by a range of successful Instagram accounts. Each individual behind the account is interviewed and they impart their story of how their account began and what made it so successful. The editors focus on what ignited the interest in so many hundreds of thousands of people.
Published just last year, the book is up to date enough to cover the stories feature (the temporary pictures and video that can be added for 24 hours to your feed with effects not available on the main feed). With regard to this and other areas of Insta photography, the book is packed with useful bite-size advice, laid out in an attractive, coffee-table format.
