I only have light perception so I cannot see an image on the digital camera's screen before shooting. I would like to know if any if you has had success using a digital camera. I understand that some digital cameras have a wheel that turns continuously which must be turned to get the desired picture in the camera's field. I understand that some digital cameras are "point and shoot" so you don't have to visually focus. Any suggestions for digital cameras to purchase, or about ease of use, would be appreciated.
