No Name Creek: iPhone Panorama

This is 12 images from the iPhone camera, representing over 220 degrees of view, taken from the same spot as yesterday’s HDR (you might want to compare). It really needs to be viewed as large as your monitor will allow (click the image and use the size controls at the top of the new window). AutoStitch on the iPhone makes this kind of shot easy. You just take roughly overlapping images and the program does all the aligning, stitching and exposure blending for a very polished result.

Often I use a panorama matrix that is two shots deep…4 across and two down for 8 images, or 5 across and 2 down for 10, but with this sweep I kept it simple. I was not about to attempt 24 overlapping shots. When you do two shots vertically you get an automatic HDR effect, since the upper shot is generally metered off the sky, and the lower off the foreground, and the AutoStitch exposure blending routine does an excellent job of preserving the best of both. With a single layer pano you lose that benefit, and, indeed, this set correctly rendered the sky but left the foreground too dark…even with levels adjustment in PhotoGene, since I was not willing to sacrifice sky detail for the landscape exposure. In  Lightroom I would have used the dueling Graduated Filter effects I have outlined in the past, but I was determined to keep all processing on the iPhone for this iPhone shot. Therefore I used Tiffin’s FotoFX app to add a .6 Graduated Neutral Density filter effect to darken the sky. Once saved, I reopened the image in PhotoGene and adjusted curves, exposure, contrast, and saturation for the finished image, which is a pretty good rendering of this huge sweep.

From iPhone 4 HDR and Pano.
