I don't have the exact prices, but you need to budget at least $100. You'll get one free picture taken after you check in. If your visit goes good, and you don't have any mishaps, the pictures are worth it. People have complained on this forum, but it turns out the pictures are done by a 3rd party company, meaning they need the high prices to stay in business. The pictures are the biggest expense of visiting DC, besides the entrance fee.
