One issue I have had with the Cameras on Windows Phone and other Smart Phones is getting the perfect picture. This is especially true when trying to take a picture of a person that is moving. For example, I will try to take a picture of my daughter and by the time picture was taken she had turned her head or changed her facial expression. So, I was excited when I hear about BLINK by Microsoft Research. What BLINK does is take a series of pictures in rapid succession and then you can pick the best picture and save it to your Camera Roll.
So, first download Windows Phone from the Store
Next Open the Camera App, and select Lenses.
Take a Picture. The Camera will take several pictures in rapid succession.
Select which Pictures you would like to save to your Camera Roll
