Your grandchildren will treasure your wedding album. In 10, 20 and definitely 50 years their technology won't be able to read USBs and DVDs and so I strongly recommend to my clients that they consider an album in their package.
There's no need for technology or data conversion, albums are timeless.
With much thanks to Rene Mussared of The Vintage Bride in Adelaide, here's something really special, the wedding album of the god-daughter of King George VI of England.
Imagine how much you would treasure this if it was your parents' or grandparents' album.
