I converted 3 Tiffs in the standalone Photomatix and saved the .hdr file, which I opened in CS3. I forgot how to do hdr in CS3 so I quickly did what I remembered.

I then used the Photomatix plugin for CS3 and got exactly what I wanted, but the file is still a 32 bit .hdr file. But when I convert to 16 bit, it looks totally washed out and nothing like the 32 bit. I believe I used the default values provided by CS3 in the dialog during conversion.

Besides not combining the 3 files in CS3, is there something wrong with my workflow here? I like the plugin version of Photomatix better than standalone and would like to keep using that instead of the standalone.

I don't use CS3, but I see no mention here in this question of "tone mapping", which is an integral part of the photomatix conversion process, mapping 32-bit tones to a 16-bit image.

I know there was a Bear lurking somewhere here.

I was actually tonemapping the 32 bit image. Is this my problem?

Edit: Using the 32 bit hdr image and Photomatix plugin. After I'm done with Photomatix it's still 32 bit.

There is an option to save-as 16-bit or 8-bit TIFF. Try that.

I don't see a save-as with the plugin, except for settings. I have no problems using the standalone version, just the plugin. Must a 16 bit image be used with the plugin?

I don't know. I use only the standalone, sorry.

Thanks, Robert.

It appears that the difference was having Proof Colors on. It appears to do this even on 32 bit tiff images. Checking proof colors off and on makes a huge difference in 32 bit and minimal (normal) with 16 or 8 bit.

In other words, I need to open 32 bit file, leave proof colors off, tonemap, convert to 16 bit, and then turn on proof colors. I tried it a couple times and it works fine this way, what I see after tonemapping is what I get after convert to 16 bit, which is what I want.

Perhaps this has something to do with my monitor not being able to display the full dynamic range?
