PHO 101
Project #6
Digital Imaging
Theory:
The conversion of light into
pixels is usually done with a digital camera, a film scanner or a print
scanner. They use an electronic sensor known as a charge-coupled device, or
CCD. A CCD contains thousands of thy light sensing elements. Each element can
convert varying levels of light into an electrical signal. The brighter the
light, the stronger the signal. The signal is then digitized and stored in
numerical form.
In digital cameras the CCD is in
the form of a two dimensional checkerboard array of individual photosensitive
receptors. Each of these receptors represents one pixel in the final image. The
CCD array is usually smaller than a 35 mm negative and may contain millions of
sensing elements. The image forming light coming from the camera lens is
focused on the CCD which converts it into a pixelized image.
Objectives:
As a result of this project the
student will be able to;
- Capture digital images using a digital camera under a
variety of lighting conditions.
- Take a photomacrograph using a digital camera.
- Process digital images using Adobe PhotoShop LE or,
Adobe PhotoDeluxe image editing software.
- Manipulate digital images to produce various special
effects possible with the image editing software, such as:
• Solarization
• Posterization
• Fitters for
special effects
• Multiple
imagery
Procedure:
- Students, working in teams of two, will shoot several
campus scenes using a Sony Mavica camera.
• Try various
lighting conditions, both in doors and outdoors, weather permitting.
• Try
photographing people as well as general scenes of buildings and interiors.
- Each student team should then shoot 2 or more
photomacrographs of interesting objects.
• Use a tripod
or the copy stand in rm. 9-161.
• Try lighting the objects using lamps available in the lab.
• Use diffuse
illumination for shiny surfaces.
- Use Adobe Photo Deluxe or Adobe PhotoShop LE image
editing software to process your digital images. You will be able to:
• Adjust the
brightness and contrast of your images
• Adjust the
color balance
• Retouch the
images
• Try filters
or other special effects
- Print your images using premium photographic quality
paper.
- If time permits, try scanning one of your gelatin
silver prints and process it digitally as well.
Equipment and Materials:
- Sony Mavica MVC-FD83 digital camera
- 3.5” High Density Floppy Disks - IBM formatted -
1.44MB
- Premium Photo Paper Glossy
Submit:
Each student will submit two
5”x7” or, larger, prints.
• One general
campus scene or portrait
• One
photomacrograph
