• You may need to focus the 35mm camera or video camera in combination with the PS-23 in order
to get the sharpest possible image.
• We suggest that you find an open space to work in. Focus the PS-23 so that the scene is at its
sharpest. For best results you should disable the auto focus (if any) on either the 35mm camera
or the video camera and manually focus the 35mm camera or the video camera. Once the image
is sharp, then simply adjust the PS-23's front lens to change focus.
*An important part to remember is that you are not taking a picture of an object that is far away from
you, but you are actually taking a picture of a phosphorous screen of the PS-23 that is only 2-3 inches
away.
