What is Stretching?

If you haven’t visited my blog over at Sky & Telescope, now’s a great time to sample them. My latest post is about stretching data, and it builds on the last few posts which delve into linear and non-linear data, and what all this stuff about “bit-depth” is about. Typically when I write or speak,…

I know it’s over…
