A few thoughts.

Camera Roll- it's what the photos are stored in on an iPhone.

Raw means an unedited file

What about an automatic back up of some sort? I know photographers who have their cameras set to remotely upload the images in real time as they are taking them. Kind of like the cloud.

Maybe not capture means we need the original from her phone. Maybe it's a photo from her camera roll that was on her screen and we could find online somehow (maybe her photos are automatically backed up to the cloud)
