Re: HDR 32 bit colors in SI and Photoshop.
Thank's Luc Eric. I have to admit the material I was given to build the Hdr had all the things you shouldn't do all in one. - Raw pics, but in 8 bits. - Bizarre compression making it looks like a scotland tissue in close up (really true). - Sun shot in the ultimate rim of the ball (10° more and it was back lighted). - Shaked shot so that the pics don't align together. So everything to have artifacts. Hoppefuly, it's not so bad in 16bits. I was just hopping it was some button I didn't check. I'm not to keen in digging into clamping values, since I'm almost sure it will be hazardous. Oh, and I made another build in Hdr shop (or was it Picturenaut ?) well I get a different result (colorwise) than in Photoshop. Spent my sunday rebuilding a fake (simple) backplate (oh yeah, they didn't shot the backplate properly). :D Le 20/09/2013 18:08, Luc-Eric Rousseau a écrit : in my opinion, you have to lower the exposure in Softimage to look at the image and see it properly, but we really don't have any HDR tone mapping toolsto deal with the highlights.

Re: HDR 32 bit colors in SI and Photoshop.
Hi Oliver, Sorry to step in this late in the discussion. When creating HDRI panos, it's best not to use PS for this. For quick stitching it's OK I guess. 32bit editing in PS is very wonky imho, and there are optimized tools for this out there. Like you said hdrshop and Picturenaut, but also PTGui (one of the best) or Hugin if you want to keep it free. Your 8 bit souce material sounds like 'fun', and a bit more colorcorrection than usual will be unevitable I guess. If you're interested in hdri pano stuff, have a look at hdrlabs.com. There's lots of info, also reviews of hdri dedicated applications. cheers, Rob \/-\/\/ On 23-9-2013 9:10, olivier jeannel wrote: Thank's Luc Eric.

Re: HDR 32 bit colors in SI and Photoshop.
Hi Olivier As default is PS always colormanaged. Have you tried to turn on Proof Colors in PS (View-Proof Colors) and set the proof color to Monitor RGB (View-Proof Setup-Monitor RGB) This way you will see the colors in PS as in all other non color managed applications.

Re: HDR 32 bit colors in SI and Photoshop.
in my opinion, you have to lower the exposure in Softimage to look at the image and see it properly, but we really don't have any HDR tone mapping toolsto deal with the highlights. It's tone-mapped in Photoshop. It's an HDR image, so it can have large yellow or red values and when you just clamp that down (i.e. truncate value above 1.0) to 8-bit like the fxview does it looks weird. You can click down in the fxviewer to see the pixel color values. Photoshop is probably showing you what you really want to see, which is an 8-bit snap shot at a particular exposure, with something to smootly filter out the highlights.
