CAMERA SETTINGS - Nikkor 50 f1.8 mandatory choice among various other objectives - Minimum vignetting ( 90 % ) with Nikkor large apertures only - Space between Camera and Microscope left open ( no tubes )


FOCUSING AND LIGHT - Best focusing view on Camera Display with 2x Digital Zoom - Use of external TV Monitor useful but image quality too poor - Low light better for details but slow Shutter Times required


IMAGE QUALITY - White Balance always bad with slow Shutter Times - Use of Photoshop mandatory for color corrections / adjustements - Eye image still ten times better than Camera pictures !..
