These are caused by hdrmerge using a white level (satThreshold) of 16383, which is to high for D700 files. I made a try with a hard coded satThreshold of 15800 and the artifacts are gone. I vote for adding a possibility somewhere in hdrmerge gui to override the white level or using https://github.com/Beep6581/RawTherapee/blob/master/rtengine/camconst.json , which would be an even better solution...\r\n\r\nHere are two example dng files with white level of 16383 and white level of 15800\r\n\r\nhttp://filebin.net/dprf4en3ir\r\n\r\nIngo"},"comment":{"url":"https://api.github.com/repos/jcelaya/hdrmerge/issues/comments/142451461","html_url":"https://github.com/jcelaya/hdrmerge/issues/72#issuecomment-142451461","issue_url":"https://api.github.com/repos/jcelaya/hdrmerge/issues/72","id":142451461,"user":{"login":"heckflosse","id":13733487,"avatar_url":"https://avatars.githubusercontent.com/u/13733487?v=3","gravatar_id":"","url":"https://api.github.com/users/heckflosse","html_url":"https://github.com/heckflosse","followers_url":"https://api.github.com/users/heckflosse/followers","following_url":"https://api.github.com/users/heckflosse/following{/other_user}","gists_url":"https://api.github.com/users/heckflosse/gists{/gist_id}","starred_url":"https://api.github.com/users/heckflosse/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/heckflosse/subscriptions","organizations_url":"https://api.github.com/users/heckflosse/orgs","repos_url":"https://api.github.com/users/heckflosse/repos","events_url":"https://api.github.com/users/heckflosse/events{/privacy}","received_events_url":"https://api.github.com/users/heckflosse/received_events","type":"User","site_admin":false},"created_at":"2015-09-22T23:24:49Z","updated_at":"2015-09-22T23:24:49Z","body":"@t-o-d-d : As you I'm also on Win64. But for hdrmerge (and for some other stuff) I use Linux in a virtual machine. The 0.5.0 windows64 version of hdrmerge is quite slow. I currently don't know why but it's not using all (8) cores of my machine. On Linux the master branch makes much better use of the 8 cores (though it does not include changes which could be responsible for the better performance). Can you confirm (by looking at the task manager) that behaviour on your win64 system?\r\n\r\nIngo"}}
