Make the exposure. Make the exposure with the preset exposure time. If the receptor is a film or storage phosphor plate, then after exposure remove the receptor from the patient's mouth, dry it with a paper towel, and place it in an appropriate receptor outside the exposure area. If the receptor is a CCD of CMOS sensor, then you may be able to keep it in the patient's mouth and reposition it for the next view. Encourage the patient along the way
