Join Ben Long for an in-depth discussion in this video Understanding pixels, printer dots, and resolution, part of Inkjet Printing for Photographers.
A digital image is made up of a bunch of colored picture elements, or pixels. …Line these colored pixels up in a grid, stand far enough away from them, and you've got …what appears to be a continuous-tone image. …It's really just like making a picture by using colored pencils to fill in squares on …a piece of graph paper. …The difference is that your typical digital image has millions of squares and each square …can be any one of millions and millions of colors. …Each of those millions and millions of colors has a number associated with it. …So to store an image, all your camera has to do is decide what color each pixel should …be and then sock away the appropriate numbers.…
Change the number for a particular pixel and you change its color. …Now as we talked about earlier, an inkjet printer works by spraying colored dots at a page. …However, your printer might only have, say, eight different ink colors available. …So a single dot of ink can only be one of eight different colors. …A pixel in your image though, can be on of millions and millions of colors. …
After a discussion of how to choose a printer, the course covers the process of preparing both black and white and color images using Adobe Photoshop. Ben describes how to take images from looking good onscreen to being properly adjusted for best results on paper, covering details such as sizing, sharpening, and color management.
With photographer and master framer Konrad Eek, Ben explores the creative decisions that photographers should address before printing. What size print? How does print size relate to the message of the photo and to the space where the photo will be displayed? What kinds of paper choices do you have, and how does your photo's content relate to the paper you choose?
The course also describes how to properly evaluate a print and how to handle common challenges that crop up during the printing process.
