Want to access a low resolution camera on an iPhone

[Don1]

I have PowerApp that saves pictures to a SQL database.  I can view the pictures in a gallery in the PowerApp.  When I use PowerBi to query the database for a report a high resolution picture is not displayed in PowerBI due to a size limitation.  My work around is to load a low resolution camera on the iPhone.  I then take the low resolution picture and store it in the camera roll.  In the PowerApp instead of taking a new picture I select it from the camera roll and upload it to SQL.  PowerBi is now able to display the image in the report.   I want to eliminate my users from having to do this in two steps.  I want PowerApps to be able to address the second camera on the iPhone.

Has anyone figured out what the address is of a second camera and how to call this from PowerApps with the Camera control?

Thanks
