So look at this thing.…I would call this red, and if I was trying to describe it to you over the phone, I might…say it's red like an Apple, and you might say a Macintosh Apple or a Fuji?…To which I would respond, no, it's a really waxed red delicious apple that's got that…really deep color, and then you might say, oh, I only shop at the organic produce market…and they don't wax the fruits there. So I don't know what you're talking about.…This is a problem with color: how do you create a language for it?…When it comes time to build a device that can send a color image to another device,…you have to have a way to describe color.…
In other words to work with color, we need a way to model it, a set of rules that describe…precisely what a particular color is.…Now there are a lot of different ways to do this.…There are lots of different color models.…We've already discussed the RGB or red, green, blue model wherein every color is described…as a mix of red, green, and blue values.…We've also discussed the CMYK model where colors are described as a mix of cyan, magenta, yellow, and black.…
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.
