About 30 years ago, this 30 years old booklet glued me to the basics of computerized image processing
with an IBM PC running MS-DOS with VGA card and a Commodore Amiga 500. The book bundled its original
"ImagePro" DOS software, minimum requirement 512K of memory, but I wanted to write my own routines
in Quick Basic and machine code.
It took me a while but when I finally completed a program that slowly plotted a fuzzy 196 x 165 pixels
grayscale image of M51 pixel by pixel on my screen I felt like a NASA scientist watching the first Voyager
images checking in. If that image was a single light frame I am taking nowadays I would not stack it in DSS though.
Anyway, today, you can display an image with a single command line in full color and hi-res, absolutely uncool.
If I could return 30 years back into the past to start it all over with this book and an orange C8, I'd probably leave
Photoshop behind and do that, but only if I can take my dogs with me.
Certainly, modern image processing software socket the simple rules of image manipulation comprehensively
explained in this precious book authored by Richard Berry.
You all, please stay safe!
