This achievement requires the following:
1. Turn tablet screen brightness as low as possible.
2. Search Google image search for "mugshot"http://www.gizmodo.co.uk/2015/03/is-your-mugshot-being-kept-...
This one worked for me.
3. Place tablet level and maximize image until it fills the red square in game. Hold the camera steady and take the two profile pictures. I held the camera around 4inches (10cm) over the screen.
4. Make a coffee in the long rendering wait. Mine took around 2minutes.
5. When the mannequin looks roughly like the image, this process has finished. My image being black &white was quite obvious.
6. Save changes and the achievement unlocks
Full credit to barad360 for raising the thought.
