She was disappointed because she discovered an entire photo envelope full of large, single negatives.
This is, as I have mentioned, not uncommon when it comes to research. I think that many researchers tend to tuck these envelopes away into "some day" when they will figure out what to do with them. I know that in my own research "some day" includes a new scanner or taking them to a professional to have them developed. The negatives don't have to stay in "some day" any more!
When she held them up to the light (because that's what we all do, isn't it?) she realized they were pictures of her family that she had never seen before!!
Knowing that the reunion is really only weeks away, she wanted to solve this problem as quickly as possible. How great to be able to present pictures that most of the family will never have seen before!!
She spoke with her sister, a photographer, and mentioned the problem. Her sister recommended scanning the negative on her scanner (no special tool required) and then loading it into a photo editing program (Picasa, iPhoto, etc.).
Then, she recommended that she introvert the colors of the scanned image. The colors of the image can be changed to black and white when introverted.
