Here are four exposures from a bracketed sequence:
Image 1
Image 2
Image 3
Image 4

Theses were taken with my Sony DSC-W5. The posted exposures should be spaced two stops apart. The full sequence consisted of 10 exposures, but the four above will be sufficient. The images were downsampled as Photobucket allows a maximum resolution of 1024x768.

Here is what I came up with:

get rid of the exif by copying the background layer and pasting it in a new document first.

Save for web strips out the EXIF, and it seems Photoshop wants to know the exposure. When you run merge to HDR a box should come up asking for the settings. All four image were shot at ISO 100 and f/5.6. Here are the shutter speeds, starting from the brightest image, 1/5; 1/20; 1/80; 1/250. It should work now.

I take bracketed shots, and I do the merge to HDR and get a really wierd image. I've been trying for ages to get the HDR to work for me...it just isn't and I feel like an idiot.

Can I do HDR with Photoshop Elements?

Nope, only CS2. Of course Photomatix is the best.

Warning:
The Surgeon General of the United States has determine that this photographer's opinion could be hazardous to your thought processes!

There are really two ways that HDR is applied at DPC:

1-For its original intended purpose which is to suppress highlights and bring out detail in images with a huge range of lighting variation for a result than can be displayed on normal monitors or printed on normal printers.

2-As an effects filter

In case #1 you would never realize that HDR had been applied at all. The two pictures above are examples of using it for the second purpose.

Generally speaking using HDR as an effects filter is OK occasionally and in special circumstances where the haloing and surrealism strongly supports the main theme of the image but probably isn't the case in most applications where we see it.

End Warning!

Are you using CS2 or Photomatix? I've only worked in Photomatix, but I know after you generate the HDR image itself, you have to use the Tone Mapping feature to get anything recognizable. I would assume CS2 would have a similar process. Hope that helps.

That is a great use of HDR, not over done....

This image is a good example of HDR when used for its original intended purpose to produce a natural looking output. The casual observer would little suspect anything special had been done with this scene. It has none of the characteristic wide haloing we commonly see with HDR here at DPC and only the slightest hint of "flatness".

I might add this is that photographer's very first attempt at using HDR and resulted in a respectable 11th place finish in the Landscape III challenge.

Here's my landscape III entry, three exposures combined in Photomatrix. It's a great tool for HDR, though not "cheap".

Without it, I would not have been able to get the exposure on both the left and the falls. I had my camera on a tripod and set to bracket 1 stop over, right exposure, and 1 stop under.

Could someone assist me. I left my camera manual at work and would like to give this a go. How do I set my camera to take 3 shots (bracketed?). If you can point me in the right direction I can take it from there. Do I have to shoot in RAW?

and no you don't have to shoot in raw but I'm pretty sure if you do, you don't even have to bracket cause you can adjust the exposure in conversion. There are many examples on here of doing it from JPG's, I have done it both ways and never used bracketing.
