Color and background pattern change
Eg pop art
Use of own library for background
Fragmentation, single color replacement
Camera can use all lenses (new phones have up to 4)
Spectrum slider, to adjust color shift
Granularity control i artistic
In general access to camera controls
But fun indeed
Thanks for sharing your ideas and feedback for the color and background pattern change!
Could you please share more details on the specific camera controls you would like to see?
