Take a filter and slowly twist it to see the effect. The Sigma filter does this much ealier than normal.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-59393360382444895082014-04-12T01:40:35.478+03:002014-04-12T01:40:35.478+03:00How did you get the conclusion that non-standard I...How did you get the conclusion that non-standard IR could cause green corners?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-37460995216443783422014-04-11T15:41:54.658+03:002014-04-11T15:41:54.658+03:00The IR filter has always been a problem for Foveon...The IR filter has always been a problem for Foveon. Still a nice Idea to capture luminance data from the blue green channel ih high res and still receiving at least 50% of the light then doing some nice math to add colour without too much noise. Probably not that accurate colour and low-res but nobody will be able to tell (JPG has proved that high-res luminance and low-res colour gives good results). Will even work better than bayer for reds on blue. I wonder if this will help the green corners which I suspect is caused by the non-standard IR filter.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-33178260264211478402014-04-10T20:36:52.789+03:002014-04-10T20:36:52.789+03:00What I can see from their sensitivity curves is th...What I can see from their sensitivity curves is that once IR-cut filter is applied, there will be huge overlap between G/B and almost completely overlap between G/R.Anonymousnoreply@blogger.com
