Speaking Notes from a Tech Talks Presentation by Nancy Reis, November 15, 2006

Types of Digital Cameras

  • Point-and-Shoot
  • Prosumer
  • Single Lens Reflex (SLR)

Some Questions to Think About

  1. How do you use/want to use digital cameras?
  2. How much equipment do you want to carry around?
  3. In what environments will you use the digital camera?
  4. How big are your hands? How good is your eyesight?
  5. How many megapixels do you really need? Compare these photos: 1A, 1B, 1C, and 2A, 2B, 2C. In each group, one photo is from a 3 megapixel camera, one is from a 5 megapixel camera, and one is from an 8 megapixel camera. Can you tell the difference? If your pictures will primarily be shared on the Web, the resolution is limited by your monitor, and you may not need the biggest, baddest camera out there. However, if you do a lot of cropping and enlarging, or if you print enlarged photos, you may want more megapixels.
  6. Why is white balance important? See for yourself: the model was photographed under fluorescent lighting with the camera white balance set at automatic, fluorescent, and tungsten.
  7. Which features are important to you?
  8. How much money do you want to spend?

[Author's Note:  Since this Tech Talk was presented, flickr has also instituted a Camera Finder which provides basic information about each camera along with statistics on how many flickr members use it and examples of "Explore" photos taken with it.]

Manufacturer's Web Sites

Camera Stores

Discount/Office/Electronics Stores


Colleagues, Friends, and Neighbors
