HDR/HDRi and Tone Mapping - - How do you treat HDR images in Photoshop

Andreas Gallas · #1 04-28-2007, 04:45 PM

I've had some problems with HDRi files from an outdoor-shot probably caused by the actinism (not with every HDRi), there were red stripes in the rendered file (rendered with mayas mental ray). I retouched the actinism and it becomes better. Now I'm wondering if there are other pitfalls or a kind of guideline, "how to treat a HDRi" someone is willing to share. I'm relatively new to the CGI-theme.

Thank you

Are you referring to creating HDR files, or handling already existing files?

Hello Doug,

I'm referring to already existing files from a client made with a SpheroCamHDR from www.spheron.com

About the only advice I have to offer is that Photoshop CS3's HDR capabilities are much improved over the previous version. Most of the tools are now 32bit aware, and there's been a serious revamp of the adjustments to take 32bit workflow into consideration. But you'd need the extended version for full painting and layer functionality.

Thanks a lot for the advice! I'll upgrade for sure.
