Negatives provide the clearest images when making copies of your prints, so it's important to keep them safe.
Steer clear. Avoid touching negatives (or prints) with your fingers. Even clean hands leave oil that can damage your shots.
Keep them together. Store negative strips in polyethylene, or clear plastic sheets, and keep them in three-ring binders, which provide easy access and protect the negatives from light. You also can store negatives in paper envelopes and boxes, but be sure your storage choice is safe for them.
Include the index print. Most film-processing orders give you an index print or you can print your own. This all-in-one guide is super helpful for identifying photos in a flash.
Separate. Take the extra precaution of storing valued negatives in a different location from where you store your print images.
Get them scanned. Have a photo lab scan the negatives to store them digitally on CDs.
