I do use the Pixma Pro series that would give said quality.

Researching my family history I found a picture online of my Great Great Grandmother and Grandfather who passed in 1877. I think it would be interesting for relatives to see you or your work 140 years later.

There is a problem with printing books and making albums. They do not duplicate well for later generations.

For that matter I didn't even know my GG Grandparents names until I started doing research. Come to find out there is a book written by a lady in Texas that researched my families genealogy. She did this because here mother felt like she didn't have many relatives. She started with the GGG Grandfather. I say this to make the point that by my generation there were hundreds if not thousands of descendants of the GGG Grandfather. When someone passes usually there is one copy of the pictures and no doubt one person takes them. When my Mom and Dad passed I made sure I had all of our families videos. Other pictures were divided up by who was in it. I have no pictures of any generation past my Grandparents and I have few of them.

A digital file is much easier to share. Every generation could share it with every sibling, if it didn't degrade.
