Focusing stacking means taking a lot of photos of the scene from multiple focus points covering the entire length of the subject from front to back, manually moving the focus a fraction of an inch each time until the whole subject has been covered. The natural camera choice was the Nikon D810 for its extremely high resolution. The lens was a 60mm macro set to f/5.6, which I have determined from prior shoots was an ideal aperture for this type of assembled image.
Sixteen photos were needed to cover the distance. The software used to assemble them into one stacked image was Helicon Focus. The latest version of this program has been much improved for speed and quality.
|This image is comprised of 16 separate photos each focused at a different point progressing from the white cloth in the foreground to the distant branches in the back. The images were assembled using Helicon Focus into one photo with extreme resolution and depth of field that even a tilt-shift lens and small aperture could not achieve.
