Good to the last drop. Multiple pictures taken with a macro focus rail and merged with photoshop. The macro focus rail mounts to a tripod and your camera mounts to the rail. The focus is fixed on the camera. The macro focus rail moves the camera in 1 mm increments which moves the focus point accordingly. Photoshop is used to merge the photos and increate the depth of field on a macro shot. This was lit with an umbrella, camera left.  ISO100 125th f16.  www.ClosePhoto.com
