One of the greatest features of the Panasonic Lumix DC-G9 is “bracketing”. Yes, like most cameras the G9 can bracket exposure. However, the G9 can bracket aperture, white balance and focus. While in camera focus stacking is possible using the “Post Focus” function, the individual images are JPEG as is the final stacked image. For RAW images and high-resolution stacks, it is best to use focus bracketing. With focus bracketing, you set the stepping distance and the number of images that need to be captured. You can also set the sequencing for how the images are captured, similar to exposure bracketing – 0/-/+ or 0/+. I prefer the second as I always start my stack from the front of the subject and work the focus away from the camera.
