Using the camera settings described on page one the following images (Fig 6-17) are taken at various magnifications. Minimal post exposure image processing is done.


 

Fig 6. Gastric ulcer biopsy from a patient with a gastric ulcer syndrome (4x objective lens).  Exposure information (EXIF data) is displayed for this image. EXIF data is stored for each image by CP990 as ASCII file (info.txt). This can be retrieved by image archiving programs (e.g. FotoStation, Thumber etc.), and also by any word-processing utilities  (e.g. Microsoft Notepad or Word).
