Photographing a youth Hostel, help

Hey.

Well my bro voulnteered me for a job to photography a friends youth hostel for their website.

All the information the guy has told me is that the rooms are about 15 meters squared, they want two different angles, they want the rooms to look large.

The theater is about 50m squared, and he said its pretty dark in there.

I've never really done something like this before so i want to get prepared.

I have at my disposal.

40d, 10-22mm.

1 580Ex II
1 Sunpak 383
Skyports, stands for both.

How would i go about lighting up the rooms? use flash or just use a tripod for a long exposure?

any help would be appreciated about framing, lighting, wtvr

thanks!

Tripod for sure.
You might need the flash for fill. Not as the main light IMO.

Is it good to shoot multiple exposures and blend in photoshop?

It might be needed if there are windows or sunlight falling through windows in the shot. Otherwise I don't think it'll be necessary.

thanks mate, and best time of day to shoot, if there are windows is it better to wait for sunset?

Depends on what you want, and how the windows are placed.
Sunlight falling in can look nice, but not in all cases.
Daylight coming in (no direct sun) can look nice, but it might also be in the wrong place.
Dark windows generally look not so nice, unless there is a nice view outside (Street scene with lots of lights or so)

You could hedge your bets and do both maybe. Wait for time of day where there's light falling through the window and fire off a few shots with natural light and maybe some minimal fill light. At same time you could fire off a few shots using the flash guns as the main light.

Then when you process them decide which works best
