Technique - Indoors
This page is a bit of a hotch potch at the moment and will most likely be expanded (firstly) and then (eventually) broken down into smaller parts.
For the time being, I am concentrating mainly on technique for outdoors bulb photography.
Generally speaking, the principles are identical.
Also, the Idiot's guide contains some very specific details (including an exercise) for indoor photography.
One thing peculiar to indoor bulb photography is that buildings tend to move more (shake in high winds, doors slamming etc) than land. This ocassionally needs to be taken into account.
