Me and Lucian have been using Google photos to share the images. He originally sent me his phone images on this as he uses a Google phone, so the images were sent on a link straight to my email. I continued to use this for ease of access, as we can both see any changes and quickly view photos and comments.
I found Google photos very useful when it came to asking Lucian to write the captions, as he added them as comments that we could both immediately see. It also made it less pressure, as there wasn’t a high tech site being used, or memory cards that needed to be handed over, so was a relaxing process for both of us.
