Review on Fujifilm Instax Mini 9 Polaroid Camera (White) + Custom Case & 50 Sheets of Film - Bundle Deal with Flamingo Designer Album by Phillip Reed

I used five cartridges of film to find out WHY this camera prints black photos with grainy white spots. I tried opening the film in complete darkness, I tried different settings, I tried different depths of field. None of my photos came out which was annoying. I called Revain Tech today and they told me to check the inside of the camera to see if there was a piece of black tape covering the shutter. That's it! WHY DID THE BLACK TAPE COVER THE BLINDS?! I read all the instructions before using but none told me to look for the black tape that would make photography impossible.
