I'm currently reading the book, Digital Film-Making by Mike Figgis. I have to say I haven't seen much of his work, except for Leaving Las Vegas, but this book is really good. It's basically a book of advice for low budget digital filmmaking. Lots of simple, practical advice.
It's a book I very much would have like to have read four years ago! But it's going to come in handy for up coming shoots. So far I've read some simple tips on preparation, budgeting and financing.
It's only 150 pages long, fits in your back pocket, I'd recommend it to anyone and everyone starting out, and I will continue to do so. Much impressed so far.
