I'm working on an app that shows the price of a product, and the end-user can update the picture for the product selected. The app will only be available for mobile phones (both iphone and android/galaxy).
This is the workflow:
- The list shows the different locations of the product.
 - Shows the detail of the item in the location, based on the row selected.
 - If the user taps "Update price with pic", then the 3rd screen will show simple instructions to end-user.
 - The actual camera for taking picture.
 
My question is related to the 3rd screen where the end-user sees the instructions.
What's the best way to display these instructions? Is it with a pop-up or the sliding pane? Or is there another more fluid way?
