When ads come to Instagram what will happen to your followers? You may lose followers, so you could check out any of these alternatives:

• VSCO Cam (iPhone, coming on Android) – Ideal for journalists not trying to doctor up on-the-scene images excessively,
• EyeEm (iPhone and Android) 
• Starmatic (iPhone) Starmatic’s filters are built around a 1959 Kodak camera. 
•  Afterlight (iPhone) not free, but 99 cents.
