How to predict your photo’s popularity before you post says Sachin Karpe. A new study out of MIT gets even more granular. Researchers analyzed 2.3 million Flickr photos to develop an algorithm that can reliably predict how many times a photo will be viewed based on social context. The algorithm factors in variables including color (warm, bright shades like yellow and pink draw more views than cool, soft tones) and the type of object featured. You can analyze your unpublished photos using a prototype on Khosla’s research page, which measures an image’s potential popularity on a relative scale from one to 10 says Sachin Karpe.
