Think of the file system on Android as something that Google grudgingly lets you have access to, rather than as somewhere you should go to configure things (much like on a Mac I suppose).
Apps have rules for where they should store their files and settings but many app authors ignore this and save stuff anywhere. If you're lucky the app will let you choose this in its settings menu, or if not it may let you back up settings to a location you specify so that you can copy those settings to another device.
I recently did a factory reset of my device and it was an extremely tedious job trying to back up as many settings as I could find. Some get synced to Google and are linked to your account, some are stored in obvious places, some I never did manage to find.
So you can't change where the camera app saves photos just by moving the DCIM folder. Some camera apps let you choose where to save photos but if the one on the Prime does then I can't find the setting
The good news is that you can download other camera apps.
If you want to have a nose around the file system I recommend ES File Explorer. It lets you access (but not change) areas that the stock file manager hides from you. Also it's very good!
