3. Introduction

4. Photomicrography
A light micrograph or photomicrograph is a
micrograph prepared using an optical
microscope, a process referred to as
photomicroscopy.
a photomicrograph is a technical document
that can be of great value to science or
industry, a good photomicrograph is also an
object of beauty.
Photomicrography encompasses the
techniques of both black and white and
color photography.

5. Photomicrography is used to study the external
appearance and structure of objects.
 The ultimate function of the microscope
and its illumination is to produce the best
possible image of the specimen.
The ultimate function of the camera is to
capture the best possible image of the
specimen.

10.  In compound microscope use a trinocular tube (binocular
tubes for viewing and a third vertical tube for permanent
attachment of the camera).
The 35 mm film cameras were used as standard for
photomicrography.
photomicrography as the camera is needed only to store,
expose, and advance the film. The microscope itself acts as a
camera lens.
The adapting point and shoot cameras to a microscope is
the very fast shutter speeds (1/25 to 1/50 second) utilized by
these popular cameras.

11. Advantages Of Cameras
cheap
portable
can be operated without PC due to “Memory Cards”
Disadvantages of Cameras
image compression JPEG or FLASHPIX
loss of resolution, image artifacts
often low spatial resolution
all single chip cameras
integrated lenses: difficult adaptation
often noisy images
