Transcript of Digital Photography
First person to create a digital camera
The camera weighed 8 pounds
Recorded black and white images onto cassette
Resolution of 10,000 pixels (one hundredth of a megapixel)
The camera was a technical exercise and was not meant for production.
Sensors and Storage
Image sensors read the intensity of light, and digital memory devices store the digital image information as "RGB color space" or as "raw data".
The two main types of sensors are charge-coupled devices (CCD), in which the photocharge is shifted to a central charge-to-voltage converter, and CMOS or active pixel sensors.
The first commercially available digital camera was the 1990 Dycam Model 1
It stored photos digitally and connects directly to a computer

Ways To Share Images
Types of Printers used in Digital Photography
1. Inkjet Printers:
Creates a digital image by propelling droplets of ink onto paper.

The copy from an inkjet printer needs a little time to dry.
Paper designed for inkjet printers is heavier than the paper used with laser printers and also more expensive.
2. Laser Printers:
It is an electrostatic digital printing process that produces high quality text and graphics by passing a laser beam.
You can print both color and monochrome images (one color images)
Laser printers are made for fast printing.
Instead of ink, laser printers use toner to print.
3. Dye Sublimation Printers:
Are the computer printers that uses heat to transfer dye on the material.
They rely on a heating process to mix dyes onto a coated paper, producing a continuous tone print.
The films are placed on the paper and heated up by the print head.
The pigments to leave the film and enter the paper where it cools re-solidifies
The prints are always dry as they come out from the printer.
