This is a highly detailed and useful handbook for video production, which tells you really all you would need to know as a non-professional film maker, aside from exactly how your software and particular camera work. Given that there are lots and lots of books about still photography, and fewer about video production, this really is as good as the best still photography books, up there with Langford's
Basic Photography as hugely informative to the beginner, but containing enough information to be a constant source of reference for years to come.
If you've spent upwards of £2,000 on the camera, microphone and editing software, then this really is a very economical way to upgrade your overall skills.
