There is this neat technique making the rounds: bracket three exposures and let photoshop combine them to get increased exposure latitude. It's called High Dynamic Range.



I can accomplish this with layers and layer masks, but CS3 has made it so much easier.



Here's the before and after of the Frost Bank Tower.


After merging them.


And after upping the contrast and cleaning up a bit.

Interesting stuffs. I have just been reading and done some experimentation on this subject.

I am trying to find out if this process is possible to achieve using pictures that are already taken, like stock images, changing their exposure within photoshop instead of taking them from a camera.

I don't see why that wouldn't work. I gotta try that tomorrow.

I am amazed to see other works of people did, editing the pictures to the point of it looking surrealistic like these:

But I like this how this, Victor Bautista did to his picture:

Do you have any idea how he did it? I have heard photomatix is the best tool for the trade. Got to get m'self that soon. Can't wait to try it out.

colin uses way more then just three pics. he does like 3 or 4 sets of three and combines all of them. thats how he gets such a broad range.

yesterday i was messing with the magic wand and using curves on just certain area like the sky or a wall. i was amazed at the difference. i'll post the results here tonight.

I think three is the minimum, five would be perfect. I guess you could get a photo targeted for each Zone, but I think that's overdoing it.

I need to try this in a more extreme situation. The day was very overcast.

I've heard about Photomatix too, but I don't like having several applications open for photos, so I'm sticking to CS3 for now.
