Digital Junk and the Demand for Photo Selection Application (by William)

During my recent trip to the Huntington Library, I took over a hundred photos with my digital camera.  The next day, I spent about an hour to delete more than half of the photos that were bad quality--blurry, random, or duplicative. 

Nowadays people often take tons of photos using their digital devices.  Later on, they either load all the photos without looking, or have to spend a lot of time going through the photos to select the good ones and delete the bad ones.  I think we should think twice before taking random photos.  Cleaning up digital junk may use up a lot of precious time.

I also wondered if there are applications that can sort photos by quality.  I researched online but couldn’t find any app that fits my requirements.  The law of demand and supply tells me if the demand is high but the supply is low, the price of the product will be high.  On the other side, if the demand is low and supply is high, the product will be cheap. 

If there is an app that can identify the bad quality photos and delete them, the developers can sell it for a good price!
