Week 1
Introduction to Digital Photography
• Beyond Point and Click
– Discussion: What is the difference between a
snapshot and a photograph?
– How do you move beyond being a beginner?
• Other Considerations
– Photography as art
– Digital photography (digital creation) within
the field of computer science
Week 1
Photography as Art
• What is photography?
• What does it take to be a photographer?
• What does it take to become an “artist”
within the media of photographs?
Week 1
Why Digital?
• Film cameras vs digital camera
• Digital camera
– Immediate feedback (can view image on lcd)
– Can take many more pictures at one shoot
• Better chance to get a great image
– Great flexibility and on-camera control
– However LCD can get in the way, causing you
to miss good photo ops (must be careful)
Week 1
Digital Creation as CS
• Digital Creation sits at the intersection of art and
technology
– Artistic elements occur when taking the raw image and providing
a vision of the final product
– Technological abilities are required to make the vision a reality
throughout the process, on both the camera and the computer
• The computer science aspect involves linking these
together – developing the technology for accomplishing
artistic ends
– Understanding the inner working of the tools will allow you to
become better able to articulate your artistic vision
– A gateway for you to begin looking at working with computers
from the perspective of a scientist
Week 1

Week 1
MDP Book
• Reading - Chapter 1: Digital Photography
from 50,000 Feet
– Quick Overview
• Make sure you get the book soon!
Week 1
Quick History of Digital Cameras
• Evolution of Digital Cameras
– Texas Instruments in 1972
• Had to view images on a television
– Sony Mavica (Magnetic Video Camera) in 1981
• Television viewing or printing to a color printer
– Throughout 80s more electronic photography
developed (but very expensive & low quality)
– 90s – more development of cameras, but low
resolution
– 2000+ - digital cameras start to become more like
good film camera
• Also photo printers became more available (inexpensive
printing options)
Week 1
Intro to Digital Versions
of Film Camera Features
• Lens Selection
– Beginners generally just use zoom
– More advanced photographers want to consider if the camera will
support additional lenses
• Selective Focus
– Beginners want an “in-focus” picture
– More advanced photographers will want isolate or emphasize portions
of a subject
• “Film”
– Digital “film” adjustments can adjust sensitivity of sensor (on camera)
– Otherwise most other film characteristics are handled in the digital realm
with software
• Color sensitivity (white balance); Retouching; Compositing; Filters; Image
contrast; Color saturation
• Will cover these topics more later…
Week 1
Digital Photography Uses and
Considerations
• Uses where digital photography has become important
–
–
–
–
Photojournalism
Portrait Photography
Photo illustration
Anything else you can think of?
• Consideration for you as a photographer
– Copyright (you own any image you take)
– Selling your photographs
– Ethics in photography (especially in photojournalism)
• Should journalists be allowed to manipulate their photos in
Photoshop? If you think so, how much manipulation is okay?
Week 1
Copyright
• Copyright is a form of protection provided by the laws
of the United States to the authors of “original works
of authorship,” including literary, dramatic, musical,
artistic, and certain other intellectual works.
–Note: it applies to photographs as soon as they are
•
taken
It gives the owner the right to (among other things):
Reproduce and distribute the work
Prevent other people from doing the same without
permission

Week 1
Fair Use
• Four factors for consideration of fair use
(no one test to determine) :
– the purpose and character of the use, including whether such
–
–
–
use is of a commercial nature or is for nonprofit educational
purposes
the nature of the copyrighted work
the amount and substantiality of the portion used in relation to
the copyrighted work as a whole; and
the effect of the use upon the potential market for or value of
the copyrighted work

Week 1
Camera Care
• See Manuals for specific care for camera
• Batteries
– Don’t trick the camera by turning it on and off to get another shot
from exhausted battery – can confuse camera’s circuitry and
could interfere with saving the file or worse – it could damage the
memory card
•
•
•
•
LCD Display – can suck battery life
Lens cleaning supplies – use to remove smudges
Camera bag for protection
Keeping camera dry
– If shooting in wet weather, use a ziplock bag (with a small hole
around the lens) to keep most of the camera dry
