(If I understood benchmarking correctly at least.) .. and surprisingly so, if you created that hdr in luminance. the reference should not be a hdr image, but the simple average of 3-4 low-iso shots at the _same_ exposure. you don't want to extend the dynamic range, but simply average out the noise in the same range. so i was simply abusing our hdr merging, which just degenerates to an average in case you feed it the same exposures. moreover, you want to make sure these are processed the same way (all linear, no gamma, no tonemapping, no different highlight handling and whitebalance etc). > All benchmarking images are out-of-focus, too. Was this correct? doesn't matter, they just have to match, as we're computing pixel differences to find the PSNR. cheers, jo > Tschö, > Torsten. > > -- > Torsten Bronger Jabber ID: torsten.bron...@jabber.rwth-aachen.de > or http://bronger-jmp.appspot.com > > > ------------------------------------------------------------------------------ > Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, > MVC, Windows 8 Apps, JavaScript and much more.
