Pete Souza, the White House photographer for the Obama administration, has been using his Instagram account to troll the Trump administration for the last few months, and is now releasing a book full of shade.

Souza often posts shots he took during Obama administration with snarky captions throwing some serious shade at the Trump administration’s shenanigans. His witty observations inspired the book.

Keeping track of votes, not predicting television ratings of his own event.

The book, SHADE: A Tale of Two Presidents, will feature over 100 photos that did not appear in Souza’s previous Obama book, OBAMA: An Intimate Portrait. The photographer says he never expected his Instagram page to become so popular.

Working with Ben Rhodes, as opposed to trying to “get dirt” on him (and Colin Kahl).

“It’s funny that people think I had some grand strategy. I didn’t,” Souza told PEOPLE Magazine last year. “I didn’t even realize what I was doing, to be honest with you. I had to look up what the term ‘throwing shade’ meant.”

Now Souza embraces the term, saying “I think it’s better not even to talk about it, to just let it speak for itself. Respectful and subtle … People judge it for what it is, which is fine by me.”

SHADE will be released on October 16, and is available for pre-order.
