Acid free paper is bloody expensive. Its madness. I recently got a heavy weight art scrap book with normal black paper. If I use it to sticky photos (Both REAL photos and PRINTED bubblejet ones) using photo corners, will the photos be subjected to some kind of torture down the road ? If it does ( I have no doubts abt it ), issit really bad ...and how long will the symptoms show ? In other words, should I stay clear and buy those expensive acid free paper, or be a cheapie and contend myself with slightly yellowed photos ?
