|  | | | Urban Pirate, may I ask how many exposures, and what f-stop spacing you used in shots 1 & 2?
Just when I thought I was out... they pulled me back in.

|
The first is five exposures, the second only 3. The f-stop was locked at a single value to maintain the same DOF for all exposures. The shutter speed values were adjusted as follows:
For the first photo the five exposures had the following values:
F-stop: 8.0
1/2500
1/1250
1/640
1/250
1/125
And the second:
F-stop: 3.5
.5
4 (seconds)
15
Hope that answers your question.
Pirate.

| | | | Thank you. I like the results your obtaining, and it interests me what are the basic exposures your starting with. I've heard some say they adjust the exposure using the electronic exposure setting. Well that not going to work if your shooting raws! I may be wrong, but I use raws directly as I understand CS2 will make use of all the exposure data in a raw file to create an HDR image.

That is how I understand it as well. However, my poor little P&S camera can only shoot JPEGs so I need multiple exposures. The shutter speed values I use are determined by what the camera's light meter is telling me. When it thinks there is good light it shows a + or - 0. If there is more or less light than optimum (I use the term optimum loosely since the camera is hardly a perfect judge) conditions, the light meter will give a number ranging from -2 to +2. So when I shoot my exposures for an HDR I usually adjust the camera settings to get me an exposure at -2, -1, 0, +1, and +2.

You would still shoot with that spacing with raws as I understand, which makes me wonder if jpegs would work just as well if the exposure setting were correct. I assumed (yeah I know...) if the raws exposure was off by exposure was off by -1 to +1 that the software would make the exposure compensation when merging as it is in the data, but not manually post processing set by me. Maybe CS2 isn't that clever!
The results your getting speak for themselves. I'm going to experiment with merging jpegs verses raws by post setting the raws exposure, converting to a jpegs, and then merging those files. The other problem with merging raws is it uses a lot of memory! Jpegs may be better to use,...oops! I appreciated your help, and feedback.

| | | | Monkey! Monkey! Monkey! Dude, did you see the vultures? They were under a stairwell right near where you were shooting.
You guys remember Bryce 3D? Made some amazing stuff. So amazing in fact that everybody started using it. And then you'd look at image and say "Oh yeah....bryce......." Now nobody uses it. And when you do see it, now people equate Bryce with crap.
HDR is heading that same route. It's a parlor trick.
I like having dark areas of my photograph recede into blackness. It's more dramatic. Often times I expose my images lighter and the compensate during post processing by increasing the shadow contrast until I lose some shadow detail.
In this example, the windows do improve in the HDR version, but I thin you could have done better to just take two exposures and merge in the new windows by hand. Let the pit and girder shadows drop off into blackness.
I've seen some good examples of HDR in a magazine. Some guys were welding at night. The photographer got the night shot, as well as the detail of the welders and even the colors of the flame in the welding arc. That was good use of HDR. So I'm not against HDR, just its indiscriminate use.

| | | | 1. shoot in RAW.
2. duplicate layer with a lower exposure value (so the window highlights aren't blown out) UNDER the original image, and erase the windows on the top layer.
3. and there's no need for HDR
in my opinion and by experience, HDR has no practical use besides landscapes.

unreasonable if the range of the chosen composition is beyond the range afforded by the sensor, and even if you *carefully* "expose to the right" and don't blow the highlights, you just might still lose a bunch of shadow detail.
the real trick with HDR seems to be keeping the highlights bright enough to be gone "almost" blown out, but still have dark shadows.
IE: shooting for a range of perhaps 11 stops, and none of this silly "I CAN DO A HDR WITH 22 STOPS OF RANGE YAY"
