AllFocusTM EDF Image Gallery - View of Mont Blanc from Chamonix
Two images of a lamppost in the foreground and Mont Blanc in the background were acquired with a Canon Digital Rebel camera and a Canon EF-S 17-85mm f4-5.6 IS USM lens. The camera was hand-held, which explains large shift and some rotation. The first image was focused on the mountain; the second - on the lamppost. The images originally were not intended for composition and were shot in program auto exposure mode. The image focused on the mountain was exposed at Av=10, Tv=1/200 and the image focused at the lamppost was exposed at Av=8.0, Tv=1/125; both with ISO=200. The brightness of the images was manually equalized with Picture Window Pro 4.0. Z-stack was processed with AllFocus V0.991. First image is the Z-stack animation, second image is the Merged Image produced by AllFocus. The merge method was best focus.
This stack demonstrates the importance of correcting rotation inevitable in hand-held photography. The amount of rotation between the two images is only 0.6 degrees, but without correcting it the images can't be accurately aligned and composed into one. After the composition the merged image was slightly edited manually in the areas where the forest is visible through the intricate details of the lamppost. Editing was done by eliminating connected components of merge masks and by copying pixels from one of the source images (after alignment) into the result within a user-changeable cursor.
