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). :DDDDDDDDD 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.
