Well, this requires math (Which sorta sucks), but you have to add up the total price from all the rewards you would like, and pledge that amount on one reward. Then send an email to firstname.lastname@example.org (or get in touch via Kickstarter) with your name and a breakdown of what you would like. We'll take care of the rest!
Well, Photography is $40 and the LP Pre-order is $25 - a total of $65. So pledge $65 for either reward, send us a note to email@example.com that says "I ordered Photography but pledged $25 more so I can get the LP pre-order too," and you'll be squared away!
