Photo-aging

The changes that occur to the skin due to exposure to the sun. This includes wrinkles and age spots.

Question: I am doing a science fair project on which photo ages sooner. Digital or Film? How do I test this? This is my science fair project, but I don't know how to even start it! I need ideas on how to test whether a digital photo or a 35mm film photo ages. I was thinking of different environments like hot, cold, humid, smoking(cigarettes) environment, etc. Please help! I need a lot of detail. So if you have any cool ideas with details, please, don't hesitate. :)

Answer: This is kind of the opposite of a cool answer because, frankly, I don't see how this would work as a science fair project. The medium on which your "negative" was created really has nothing to do with how a print of the photo ages. That would vary based on the type of paper, processing, etc. that was used to create the print. In other words, photo paper doesn't know or care whether you've printed from a digital source or film - it makes no difference. You might be able to make it work if what you're testing is "mass-produced" prints (like from the photo counter at Walgreens) vs. professionally produced prints (by a photographer using darkroom equipment) - which one would age more quickly under various conditions.
