My grand father really loved photography. Loved animals and was a vet and owned a medical lab for running tests in the late 1880+ I have many of his printed images, very few negs. Others along the way must not have thought negs were not important. I have printed images from my father, few negs too.

For myself I have "pounds & pounds of negs and slides" plus many prints. Many prints, more mounted than loose. I also have a library index card file from a library filled with CDs and data DVDs. Several hard drives on the shelf filled with digital images since 2003 when I got my first DSLR (Nikon D100). Unfortunaly all of it is in the same home, ours. I know better but, failed to act as yet on off site storage.

Your loss is tough, but it is my motivation. Hope you can recover some of it.
