Join Ben Long for an in-depth discussion in this video Defining resampling and interpolation, part of Inkjet Printing for Photographers.
Let's say you want to reduce the print size of an image. …By now you should be getting comfortable with the idea that as you do that, resolution will increase. …So for example, if I have an image with a print size of 8 x 10 at 300 pixels per inch …and I resize it down to 4 x 5 inches, my resolution will go up. …It will go from 300 pixels per inch to 600 pixels per inch. …Don't worry about understanding that math. …Just trust me, that's how the resolution will increase. …The important thing to understand is that as print size goes down, resolution goes up.…
But let's say I'm giving this image to someone who says they need the image to be 300 pixels …per inch, but they need it to be 4 x 5 inches. …Now I have a problem, because my image has too many pixels. …At 600 pixels per inch, a 4 x 5 inch image has 2400 x 3000 pixels; at 300 pixels per …inch, a 4 x 5 inch image has 1200 x 1500 pixels. …So I need to throw some pixels away. …Resampling is the process of taking my collection of pixels and selecting a new sample of pixels …
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.
