I’ve been busy over the last 10 days reediting older material to form a book on writing HTML galleries for Lightroom. I’d written quite a lot of it before, but the code base was out of date, so essentially I’m rewriting the code and adding on a lot more to it. I’ll be presenting it to my publisher when complete, and if they don’t want to take it, I’ll look at the e-book route.
The book includes the plugins being created at various stages, so you can look at what’s happening and form a reference for future plugins. It’s not meant to replace the SDK, but to compliment it. I’ve written it to work by example, rather than hard core API material. Along the way I’m adding in tips and workarounds for things. For now this is one of 2 or 3 core projects I’m working on, so if things are slow here, you know why!
Sounds like a very useful book, which would fill the gap between most books on Lightroom & the SDK.
Hope it appears soon as I'm bound to need it.
