H-D-R image tonemapping

[thoreau]

anyone on LJ into High Dynamic Range Imaging - and know how to pull that off in Photoshop - or know of a tonemapping referenc e out there?

for example, the below image is a photograph of the Golden Gate done in HDR:

WOW. Those are beautiful. I would ask lj user: Daikon

these in large printable format could be overwhelming I think :) I'll checkout daikon - thank you!

Totally!

Using a locked down camera you take 3 pictures at 3 different exposures.

One at the correct exposure, and then one stopped a little farther down to get all the detail in the shadows, and then the reverse of that to get all the highlight information.

Then using photoshop (or HDRmerge which I hear is better) you combine all 3 pictures using the FILE>AUTOMATE>MERGE TO HDR

then you can play with all the settings to get it looking how you want.

This website helped me out when I was learning about it.
I don't have an SLR or a shutter release so it's hard for my camera to do what's needed. The camera can't move AT ALL and it has to have a manual mode to be able to change the exposure.

Hope this helps!

Thanks for the excellent explanation! ... I'm a virtual Luddite when it comes to photo manipulation, though I'm accustomed to working with SLR and digital cameras. So your comment was really enlightening.

Actually, you take some number of pictures, depending on what dynamic range you want.

And you don't have to keep the camera completely still. It's best to have the camera on a tripod, but HDRMerge (which is supposed to be great) or Photoshop can make up for a bit of camera movement.

Wow, what a cool effect. Looks like I would imagine a pharmacologically induced hallucination would like like (not that I have first hand experience).

i love how the technique brings out different things out in what you are photographing. the car details on the golden gate - the random art of a weed field - and the subtle and no so subtle colours and fonts and words on the hotel. super duper! You should see boyshapedbox's explanation in another comment.

Wow! - you've started something exciting, including some excellent comments from LJers. As one of them said, the pics look like they're pharmacologically induced - cool. Another gave a clear explanation (at least I get it in theory)of how it is done. Pass the pills and the water :0)
