I promise I have tried this "easy" change several times and nothing... having one RAW file, create 2 more with diff +2 and -2 exp. so then I can use PM to generate a HDR?
Please advice
Thanks

I'm not sure what you are asking. It sounds like you want to know how to create an HDR from a single raw file. Take one of your raw files, and make 2 copies of it. Then open DPP, adjust one of the raw files to -2 exposure and adjust the other to +2 exposure. Now you have 3 files with -2, 0, +2 EC. Import into your HDR tool of choice.

well yes, that is my plan... but I can't change the exposure of the 2 new RAWs in DPP... what feature/option you use to do that in DPP?

I only see these options... any comment will be appreciated.

"Brightness adjustment" is the one you want.

What other software do you have? I think any editing program that allows a copy - pase should do.
What happens if you just set 1EV in PM (what software is that by the way? The only PM I can think of is "PhotoMechanic" ;))

Photomatix.
If you open the RAW in DPP, you can't make more cr2 files, you need to make tif's with +/- 2 exposures and one at zero. Then import the tif's to PM.

DPP - or any other RAW converter - will never make any changes to the RAW file. When you edit an image in DPP and then save the changes the new parameters are listed in the metadata attached to the file but the actual image data is untouched. This metadata can be read only by DPP, so if you open the file again in DPP you will see it with its new characteristics but if you open it in another program you will see no change. In order to create new images in which the actual image data incorporates the changes you want, you have to do 'Convert and Save', thereby creating three tif (or jpg, but tif is better) images which you can then open in your HDR application.

Good point. Missed that.

I feel stupid already, I did the convert and save step, to TIFF, I tried both option, TIFF 16bit and Exif-TIFF 8bit... and the TIFF files still don't show the +1 -1 factor in EV... therefore PM still says that all the files are the same

Are you using the "Generate HDR image" button in PM? It should open a file picker window, where you pick the files on the hard drive, then open them. If the EXIF showing the exposure value isn't there, you should get a window to set each one manually or just select the 1 stop difference. But, you have to "select" the one stop difference each time you do this, it isn't automatic or by default, even though it looks like it is. In other words, your telling Photomatix what the exposure values are, cause it can't find them in the file.
I don't have a lot of experience with DPP, but to make life easier, you should find out how and what to set so the exported files include the EXIF data.

Two ways:
One: Just go to "single file conversion" in PM and open your raw file, you can then tonemap the RAW file and create your HDR. This is exactly the same as pulling different exposures to create the HDR because when you use a single RAW your RAW IS the HDR because all the information is there.
Two: When PM says all the pics have the same exposure put -2 in the underexposed pic, and +2 in the overexposed pic, assuming your bridghtness adjustment was -2 and +2 in DPP.
Hope it helps

Why even go through making separate files in DPP? Photomatix can do single RAW file conversions (it's under Automate>Single File Conversion).

OK...so when you get this window and PM is not able to detect the correct settings...you can tell PM what the correct exposre settings are...double click on the interger value and PM will allow to enter the right settings..
that's what I do when PM does not detect the right exposure settings...
