Yes. Even if they're literally a big jumble of photos and negatives of all shapes, ages and sizes, we can do our best to scan them accordingly, so that you can have all of your photos in one place, safely stored on your harddrive (which we recommend backing up every so often).
Of course, the one thing we can't do is categorize your photos with dates, etc. Unlike digital photos taken with a digital camera, hard negatives and photos don't have a timestamp or a "Date Taken".
