We all have our little pet peeves and one of mine is when certain words aren't used …correctly, and resolution is a term that is almost always misused. …In digital photography terms, resolution is simply a measure of how many pixels there …are in an image over a given area. …So if an image has resolution of 72 pixels per inch, then no matter how many pixels there …are in the image, they are spaced so that it takes 72 of them to cover a one linear inch. …Now many people, including camera makers and vendors, will speak of a camera having a particular resolution.…
This camera has a resolution of 14 megapixels. …14 megapixels is not a measure of resolution. …It's a pixel count. …A camera doesn't actually have a resolution. …Sure, the pixels on the sensor are spaced a particular way, but that's pretty meaningless …in the real world, because the sensors are so small. …The fact is, an image can have any resolution that you want it to have, because you can choose …to space the pixels closer together or farther apart. …
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.
