Previewing 180+ degrees videos
Posted: Sun Jun 09, 2013 3:04 am
With fisheye imaging live feeds it is hard to see what is going on at the image periphery unless the feed is dewarped. Magic Lantern the third party firmware for recent Canon DSLRs can do live preview in camera in dewarped form. Either as rectilinear or "Panini" perspective. The second especially is good for getting an undistored version of 180+ coverage. Then you can film exactly as you can render out the corrected views .. like here

also it is much easier to hold the camera system steady and keep it level if you have a suitable non-fisheye perspective to look at
also this feature works when shooting Raw too with the latest firmware so you can get an accurate non-fisheye preview plus improved latitude and detail
