More About This Textbook
Overview
Digital imaging is now available to all amateur astronomers at a reasonable price. The advent of CCDs, DSLRs and – perhaps most significantly – webcams mean today’s astronomers can make colorful planetary or deep-sky images of breathtaking beauty.
The results obtained with even modest equipment can be spectacular, but of course they depend crucially on the computer processing of the images after they have been captured.
Enhancing Digital Images is not just an introduction to image processing, it is a deeply practical, comprehensive and fully illustrated in-depth guide to using a digital camera, performing image reduction and undertaking image enhancement – all without jargon or math.
Here is everything you need to know about processing digital astronomical images, regardless of whether you are experienced or a relative beginner!
Editorial Reviews
From the Publisher
From the reviews:"This book is packed with sound practical advice about digital imaging. … The book is aimed at beginners and experts … . there is plenty of information in this book and it gives an excellent general overview of the subject." (Pete Lawrence, BBC Sky at Night, August, 2007)
"This recent addition to Patrick Moore’s Practical Astronomy series is chock-full of helpful tips for anyone considering attaching a camera to a telescope. … I highly recommend it for beginners or for advanced imagers who concentrate on one photographic discipline and need an introduction to the other ones." (Sean Walker, Sky & Telescope, November, 2007)
"Privett has certainly packed a bundle of useful information into one hundred and fifty pages, with hardly an equation in sight! … His advice is both relevant and concise and clearly reflects years of practical experience … . There is a good index at the back as well as useful appendices on hardware and software, and a helpful list of acronyms and abbreviations … . I got a good feeling from this book – a nice blend of genuine enthusiasm and expert knowledge comes clearly across." (Gerard Mc Mahon, Astronomy and Space, December, 2007)
