I went to Blacks near work and paid $20 with tax included. Because I was pressed for time, I paid it. But I am sure you can pay much less elsewhere. Also, I got a "free" cheap passport case with it - oh joy.
Since the passport office is really busy right now with the new US restrictions.
Go to TWO places and have a photo done. I know it's a pain in the ass but I had a Blacks photo for passport purposes refused by Immagration and then had to go and get another one done delaying the processs. The advice at the time was get TWO done from seperate places that way one will be acceptable. Depending on the immigration employee they can get quite picky.
Guess I lucked out then. I went to Blacks but the guy had so much trouble getting the photo that his boss gave them to me for free - two colour and two B&W along with the passport holder.
He gave me the two types of pics because he says that, depending on which office you go to to get your passport they prefer one or the other.
Passport pics can be tricky under the new rules 1) no glasses 2) no flash should show on cheeks, 3) must be a full on face shot showing both sides of face clearly.
And yes my pics got rejected on all 3 counts 3 times!
