St Nonna's Church in Altarnun Cornwall

One of the advantages of having an IR converted Canon 50D is that I can make full use of Magic Lantern to capture the best data.

These three images are from the village of Altarnun (meaning: "altar of Nonn"). 

Wiki tells us that the dedication is to Saint Non or Nonna, who was the mother of St David. The church is mentioned in Daphne du Maurier's Jamaica Inn; it is the church in which the evil vicar of Altarnun depicts himself in a painting as a wolf while the members of his congregation have the heads of sheep.

The image was taken near noon and I used the following workflow to get the best out of my 10-20mm Sigma lens:
  • I set an aperture of F/3.5 for the Church and F/8 for the bridge shots (as an experiment);
  • Once I was composed I used ML's Auto ETTL to set the correct exposure: 1/500s at F/3.5 and 1/100s at F/8;
  • I moved the lens focus ring to the full macro setting and ran my auto focus stacking script, with bookends enabled;
  • Once I had ingested into Lightroom, and did some basic corrections on one of the images in a stack, I then synced the other images in the focus stack to this base image;
  • I then did a round trip to Helicon Focus and tweaked a few things in Photoshop and SilverEfex Pro.
As usual I welcome any feedback on this post.

  1. I like IR very much. I believe, the corners don’t look proportional in the most of WA shots.
    Photoshop Adaptive Wide Angle filter (or any other similar tool) brings out that distortion. The lost corners can be cloned or content-aware filled. See example:
    But, maybe, it’s time to try an IR focus-stacked panorama? :)
