Well this article is for a newbies. If you have some information to fill up, I would be thankful.
So what you need to interior photography? First of all your camera :) Then it is helpful to have lens at about 10-20mm angle diapason. If the room or hall is quite big, then it could be enough to have at about 30mm angle lens. But if you want to make photos of ordinary home interior, 10-20mm angle diapason is really helpful.
I don't used any flash or other light apart from light that comes through the window and the bulbs light, that is a part of interior.
I used aperture from 11 to 16 so in some cases the time of taking photo were 10 or more seconds, that is why you must to have a tripod. If you want a tack sharp picture - use mirror lock up function of your camera. And obviously you must use the remote controller.
The basic composition rules is also needed to know if you want to make an attractive photo.
I take pictures in RAW file format, I like it because I can control exposition better.
That's it, good luck!
