Do your old slides look like this? We hope not! Damage to improperly stored media can render it unable to be transferred. While we try as hard as we can to retain all the images, sometimes we are given media that is just too far gone to save.
Just because your media doesn’t look like this yet, doesn’t mean a rainstorm and flooded basement or leaky attic won’t get to them. Transfer now to prevent this from happening. It really is a great idea.
