While Pete Souza was busy documenting the life of President Obama, photographer Amanda Lucidon was following around Michelle, capturing her every move from 2013 until 2017.
Lucidon's new book, "Chasing Light," is more than 200 pages of the former first lady's time in the White House, along with personal accounts from Lucidon herself.
"It was a remarkable experience," Lucidon told Business Insider of her time documenting the first family.
Ahead, a look at some of the best photographs from the book.
