I’ve been exploring some of the new features in Photoshop CS6 – most recently, the Adaptive Wide Angle filter. This new filter piqued my interest from the moment I heard about it and I’ve been anxious to try it out. To do that, I chose this HDR image of St. Francis Church in Kalaupapa, HI. It was taken using a Nikon D300 with a 10.5 mm DX fisheye lens. I like the fisheye distortion here – after all, it’s why I bought the lens. But, this effect might not be for everyone, and I wanted to see what the image would look like if it were corrected. And, it was a perfect opportunity to check out the Adaptive Wide Angle filter.
For comparison, here is the same image after applying the profile correction for the 10.5 mm DX Nikon fisheye in Lightroom’s Lens Corrections panel. While I’m sure that this correction is accurate, I’ve never liked the results it gives. Each time I’ve tried it the foreground is over-emphasized and the perspective seems unnaturally elongated. In this case, it makes you feel like you’re accelerating toward the altar at warp speed; so, I suppose there might be a statement in there somewhere. Still, it’s not what I wanted.
For this version, I started with Photoshop CS6′s Adaptive Wide Angle filter. It is very straightforward to use – just click and drag along lines that you want to be straight. After applying the filter, there was still some pin/barrel and vertical distortion, though. To remove the remaining distortion, I tried adding Photoshop’s Lens Correction filter but the Lens Correction filter felt clumsy, and I couldn’t get the results I wanted. I really wanted to try the new manual corrections in Adobe Camera Raw’s Lens Correction panel, so I used Russell Brown’s Edit Layer in Camera Raw script to create a Smart Object that I could use to access ACR. Much better – the result, while not perfect, is very believable. It almost feels like you are standing in the church.
