"For advertising purposes, which are becoming more important to the imaging industry, the visual content of personal photographs is already secondary to the metadata addressing who, what, where, and when. The growing importance of metadata is changing people’s relationship to photographs. No longer are photographs predominantly visual objects for communication, identity-building, and memory. The digital photograph is also a container of information that can be linked to other information in a heterogeneous infrastructure."

Summary:
Domestic photography has shifted from being simply about storing memories, developing a reliance on metadata to give context on location, subject and have ability to add to an interconnected web of digital information.
Critique:
This conclusions drawn in this book reflect the academic consensus regarding the changing tole of photography, indicating accuracy and reliability. It also provides an in-depth look at the history of change in the significance of photography through the shift from the analogue to the digital world. I would recommend this source to anyone wanting to gain a foundational understanding of the significance of photography over time.
My Takeaways:
I should portray film photography as a simple and nostalgic process free of metadata; simply a photo.

New Approaches to Digital Photography and Online Photosharing - Serafinelli, Elisa
"Active users share photos regularly to communicate about themselves. This shows that the practice of photo sharing becomes part of people’s routines."
"Nowadays, taking photographs does not seem any more a practice dedicated to the maintenance of family and domestic memory, but it is turning into a means of identity disclosure and communication"

Summary:
Photography is now less about the maintenance of memories, but is seen as a part of personal identity.
Critique:
This source affirmed for me the shift in the role of photography from a way of recording memories to a component of peoples' identities that I read in From Snapshots to Social Media - the Changing Picture of Domestic Photography. This took a different approach, however, exploring human identity rather than the history of photography.
My Takeaways:
I will hearken back to times where photography was about recording important events, places, times and things.
