| It's reading the EXIF and knows that it's all from a single image. Strip the EXIF and it should be fine. |

| I don't know how to do it in CS2 since I use Photomatix and it doesn't care about the EXIF. I believe with the Canon RAW conversion tool that comes with the camera it will strip EXIF for you if you don't have it checked. |

When I first started doing this witha single RAW file, I would open the file three times with different exposures, then use the Save For Web option at the highest setting to strip the EXIF. By doing that I could combine all three by manually entering the exposures. someone then told me I was losing half of the color data by doing that.
Try this. Open the file, then creat a new file in Photoshop. Copy the file you opened and paste in on the new file. Then save that new file as a 16 bit TIFF and see if that strips the EXIF data for you. Otherwise do like I used to do and use Save For Web until you get your hands on Photomatix or another HDR software that is able to do what CS2 can't.

The drawback with this method is that you are now trying to HDR merge with 8-bit jpg files. You started out with plenty of pixels when you were in RAW, but now they are "thrown away" when saved for web.
Having said that, get a utility that will strip out the EXIF info from RAW or TIFF files. Opanda is one that comes to mind.
Another method is if you use Windows Vista (and maybe even XP), you can right-click on the image (either on the thumbnail in Windows Explorer, or on the image when shown in the free Windows Live Photo Gallery). Then choose "Properties", then choose "Remove Properties and Personal Information", and then follow along with the screenshot shown below...

Create and save-as 16-bit tiff each of the different versions. Open each in Photoshop, select all, copy, open new document, paste, save-as new filename, and you have the identical 16-bit document without exif data. It sounds more complicated than it actually is.

You must have stopped reading after you quoted my line. I went on to say:

You are correct--I glossed over the remainder of the message. My bad. :-(

Jib,
Simply converting is not enough. Do this:
1. Open the file in Photoshop.
2. Open a new file (a blank one)
3. Copy the file you opened and paste in on the canvas of the new blank one that you opened.
4. Save the new file that you pasted onto as a new file (ie, HDR1)
5. Repeat these steps with all of the exposures that you want to creat your HDR with.
6. Go to Merge to HDR and choose the files you created (HDR1, HDR2, HDR3)
By copying and pasting like that you should not be copying the exif data of the photos, so you will have to manually enter the values.
I just double checked this to make sure it would work and it did. Something to remember:
When you creat the new file, make sure you choose 16bit, otherwise you are wasting your time by doing this process.
