Unlike the other cameras that take an image after you tap the shutter button, Pix Fix keeps taking the images until you tap the button.
So, the meaning of the Button is now “Stop! That’s a wrap!” instead of “That’s the moment, ooops I’ve missed it”.
After clicking the shutter button you have a series of photos taken before the click. You can then pick the photos where the moment is captured or save the whole series.
