I read through some of the forums and this particular one puzzled me: "In regards to the flash, mount it to your hot-shoe and point it towards the ceiling. This will give you the ability to bounce the flash, giving you more even coverage throughout the studio/room and more natural looking shots indoors." How do you mount the flash? What is a hot-shoe? Can the flash be removed? How do you hold the camera to get the flash to bounce off the ceiling? I'm lost!
