I spent time exporing what I could do with the front-facing camera on my Kindle Fire. Normally this camera is used for video chats, but with the help of a downloaded app called ESFile Explorer it is possible to do more. ES file Explore adds panorama and normal camera shooting as well as video at 480p, and 720p. Since the camera is front-facing, it is a little awkward to shoot a scene, but it is doable if you really want to record the scent.
This was a good exercise in seeing how one can extend the capability of a mobile device.
