It appears to give better results than rectilinear or orthographic. Can somebody confirm the same?Lost Wandering Drifterhttps://www.blogger.com/profile/06336395980835843766noreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-41467242343324435062016-03-01T16:43:31.044+00:002016-03-01T16:43:31.044+00:00Great read.

This applies to photos taken using all formats: 4/3rds, APS-C, FullFrame, etc. I hardly ever use rectilinear projection due to the extreme stretching of the edges. I have found that depending on where the horizon is in an image, sometimes equirectangular, circular, stereographic,Glennhttps://www.blogger.com/profile/00324167942857605125noreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-60579446982027013262013-10-22T06:32:37.087+01:002013-10-22T06:32:37.087+01:00Sorry, I haven't used LensFun.Sorry, I haven't used LensFun.Fredrik Gløcknerhttps://www.blogger.com/profile/07523430148487818493noreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-27586766685013500742013-10-22T00:50:36.687+01:002013-10-22T00:50:36.687+01:00Thanks.

I followed your instructions with Hugin and GIMP (neither of which I had used before) to de-fish some photos with the Samyang 7.5mm on my GF3: it's like gaining a very wide rectilinear lens. I haven't yet tried with stereographic or Panini. Have you tried using the LensFun lens database--if so can you give instructions?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-1428159317362887862012-05-19T00:44:11.175+01:002012-05-19T00:44:11.175+01:00This lens is stereographic so that's the best ...This lens is stereographic so that's the best profile to use in Hugin.<br /><br />Also it is worthwhile tweaking the focal length (or focal length multiplier) by very small amounts (e.g. 0.02) to get straight verticals (rather than barrel or pincushion distortion).<br /><br />Finally, the Panini projection is worth playing with.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-92128735934029815112012-04-09T14:43:34.114+01:002012-04-09T14:43:34.114+01:00In terms of field of view, this guy(http://www.ugl...In terms of field of view, this guy(http://www.uglyhedgehog.com/t-20057-1.html) took photos with the same landscape at 7mm on the panny and the 7.5mm sammy fished. You can see a big difference in field of view you lose is about one eight less on panny at each end of the diagonal. The example on this page loses very little from the actual image so on that matter only the cheaper manual fishy lens Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-813055710667942720.post-5954812799039412572012-03-30T10:43:47.757+01:002012-03-30T10:43:47.757+01:00Very interesting results :)
