HDR image with flash light...

So, what if we have the place with a very very very poor artificial lighting...(okey, no lighting almost) But we have flashlights..
What should we do to achieve HDR look?

Long exposure and flashlight(s) pointing at a refector that is reflecting back at the subject(s). This will provide lots of light everywhere and the very long exposure will make up for the rest. Put everything attached to stands as holding them may be a pain.

My thoughts,

Re: HDR image with flash light...

Sounds more like a technique called "Painting with Light" to me. Basically it consists of opening up the cameras shutter, "painting" the scene with some kind of light source, then closing the shutter.

Years ago I and some friends took a photo of an aircraft carrier (which was tied to a pier) in the middle of the night, took a whole lot of flashbulbs, one at a time! But one can use something like a flashlight, just keep it moving, and do your best to remember where you have already "painted" and where you have not!

Or just run your single images thru Photomatix Tonemapping part. That will give you the look.

"Painting with Light" does make sense...but by flashlight I mean photoflash ) not the electric torch )) I'll try..

Well if you can get the flash wide enough, try a long exposure and multiple test flashes until correct exposure.

You could also try moving the flash into different angles, kind of like the painting with light.

Yes, you sometimes need to run a denoise program first.
