ACR not embedding EXIF data in saved tiffs

<p>When I making HDR images I bring my bracketed raw files in to ACR and save with no adjustments as a tiff and then bring them into Photomatix. I've read that ACR is supposed to embed the EXIF data in the tiff file, but its not doing this. What am I doing wrong?</p>

<p>I don't think it works with HDR images because the camera/exposure data is not constant for all the images.</p>

<p>When doing a batch conversion in Photomatix Pro, one of first things that I see as it starts the conversion is something like this "No EXIF data available" so I think it does use this info. I'll take a closer look at Photomatix.</p>

<p>Here is what I've found on the Photomatix web site.</p>

<p>Creating an HDR image requires to assign an exposure to each source image. Photomatix automatically retrieves the exposure information from EXIF data. When the images do not have EXIF data, Photomatix will let you enter the exposure values manually, or automatically estimate them when running in batch mode. <a name="differences"></a></p>
