This is what I thought of the difference between digital crafts and scrapbooking. Scrapbooking is photo storing in a unique way; you give embellishments, additional texts, and pictures around a photo to make it look unique and memorable.
Indeed, scrapbooking can also be done digitally. It means, using digital elements to decorate photo in photo editor software. You can add ribbon, lace, flower, etc which are all in digital files (JPEG, PNG, GIF, etc).
However, digital crafting is not only about photo; it’s a crafting activity that is usually done manually (such as making greeting card out of hard paper, ribbons, etc) now done digitally. You can make a lot of digital crafts instead of mere photo albums.
Some of the digital craft products that I have known are; recipe cards, calendars, bookmarks, photo frames, etc. The same digital elements or embellishments used in digital scrapbooking can also be used in digital crafting.
