I'm thinking of greatly expanding my lunar eclipse photography guide to include the basic foundations of what's going on from a science standpoint and from a photography standpoint (like explaining histograms rather than including a link to a website). I also wanted to do more advanced stuff with layout and images, including screenshots of processing steps, call-out boxes, etc. (so more like a modern textbook than an essay). I was thinking InDesign would probably be best for this (since I'm pretty good with Photoshop and don't want to mess with nor buy Quark). So a few questions: (1) Am I right - is InDesign the right software for this project? (2) When doing this, I assume that you actually write the text first in something like Word and once you get the words right then you go into the actual layout process? (3) Is InDesign difficult to learn if I know Photoshop? I opened it briefly and it looked similar, but it seems to have quirks that are quite different from PS. (4) Anything I missed?
