HDR Image What Next?

i used photomatrix to create the HDR image, it looks a bit strange, but when i use the little "viewer" that pops up it looks excellent.  What do i do with this file? I'm sure i save it to use elsewhere, but how? i tried saving as .tiff but i couldn't open it with photoshop. any ideas?

Are you generating the HDR image or are you using the Exposure Blend method?

I'm no expert, just experimenting with it myself. With HDR you can't just save it as a tiff -- well I suppose you could, but Photoshop wouldn't be able to use it. Anyway, on the menu, click HDRI and select Tone Mapping. Here you can adjust the image to your liking and save a lower dynamic range image that you can open in Photoshop.

You'll have to do a lot of experimentation to get something you like. And the preview image is not necessarily what you'll end up with (that's just dumb, why bother?). But with practice and trial & error, you can acheive really good results.

On the other hand, I find that most of my images come out just fine with Exposure Blending. I then bump the saturation up a bit in Photoshop.

Hope tyhis helps.

After you generate the HDR image you have to apply "tone mapping". It is in the same menu as HDRI. You will then get an image you can save as BMP or TIFF.

You should read the help file that comes with Photomatrix. It has clear instructions on how to use HDRI.

Also you should read the FAQ located here

If you read these documents your questions will be answered.

Hi,

Sorry for the question but I can't seem to figure out this program even after reading the their FAQ. Most of that stuff just went over my head.

Gen.Lee, what is your recommended procedure?

What are your recommended settings for HDR & Tone Mapping?

I'm hoping I can get an idea what parameters I really need to adjust to get at least an acceptable result.

Thanks,
eagle

When I leave the settings at their default I get decent results. I have found that even small changes to the settings affect the image quite a bit. You really need to set some time aside to just experiment with all the settings to find something that's acceptable to you. Like you, the information on their website was over my head.

But for the majority of my images, using explosure blending and bumping the saturation in Photoshop has been the way to go for me.
