Nowhere to be found. I scanned it.
A First Course in Atmospheric Radiation – G.W. Petty
I saw a request for this elsewhere from almost 10 years ago. I scanned it, but I still have to process the PDF and djvu.
How do you scan your books? Don't say "scanner," I got that part; I meant kind of method did you use? Just a flatbed for each page manually? That's a lot of work.
Do you still have your textbooks after scanning them?
Flatbed, but to save some work you don't have to click a button for each page. You can set "pause for 3 or 4 seconds", then you just have to flip the pages and turn around the book without having to click for each page. The average speed is 200 - 250 pages per hour at 300 dpi no colors. 600 dpi halves the speed and is not worth it, unless the page has really fine grain details. With colors the speed is about 50% slower compared to grayscale.
The most time consuming part is not scanning itself. It's using photo editing and image processing to align all pages, remove the paper's texture, fix text that is deteriorated, dirty stains and etc. Making all pages have perfectly black text and perfectly white background is what makes possible to compress PDFs to very few megabytes, compared to PDFs that are made up of raw images that take up hundreds of megabytes. JPG was never meant to compress images of book pages.
The books were borrowed from a library.
A lot of work indeed!
Thanks!
EDIT: Just one more question: which software did you use to scan?
Finereader, but even irfanview can work with the aid of a macro recorder to automatize "click to scan".
