| Re: Best way to back up photos?
In what sense "backup"? You can't really "backup" prints, you can use proper archival storage for them and the original source films to save them for the future.
Backing up digital photos is best done on good quality archival media (DVD/CD) burned at 1x speed and stored in archival conditions.
If you have old/vintage prints you just want to digitise then any decent flatbed scanner will scan them good enough for most folks.
Better to scan the negatives rather than prints, getting it done for you is pricey though. Be careful cleaning dust off before scanning as it's easy to scratch originals by wiping dust across them!
Scan in full colour rather than black & white to retain the printed tones of the black & white print but note that what an old print looks like now may never have been the intention. Old negatives & slides deteriorate and take on colour casts very quickly if stored cheaply. |
