The GoPro ‘Hero’ camera is an obvious choice for KAP; just pick one up and you’ll see why- it’s wonderfully light and ‘HD’ too! So for a while now we have been seeing a growing number of ‘bug-eyed’ KAP shots and for me the novelty has worn off pretty quick: so much of the detail gets ripped apart by the spherical distortion. I reckon only a third of the image is useful for anything other than to sit back and gasp at the width! Spherical projection is no big deal (there is only one variable right?) but there are a number of ways of re-projecting the image to a more ‘human’ perspective. I’m going to show here how I achieved the shunt in Adobe Lightroom by fooling it to recognise the lens properties of the GoPro lens.
Here is the off camera image:It’s taken by Matt nh http://www.flickr.com/photos/68177735@N00/6719422123/ of Zoutkamp in the Netherlands and he has asked me how to De-fish it.
In Lightroom the ‘Develop’ panel has a Lens correction sectionand there is no lens profile availabe for GoPro but from the Exif I know the focal length is given as 16mm so by scrabbling through the available profiles I plumped for a Nikkor 16mm AF fisheye- the closest thing.
And the applied correction looks like this:Now I can switch from ‘Profile’ to ‘Manual’ control of the lens correction:and push the ‘Distortion’ slider (+58) to smooth the perspective a bit. Then the corrected image is exported and that’s the job done!
