We are going to be adjusting the aperture & shutter (setting the ISO just once) in manual mode today.
The steps are:
- Set image quality to RAW
- Set ISO to 400
- Find a magical scene to photograph (remember compositional rules)
- adjust aperture and shutter so your light meter is centered
- Take pic
- re-adjust aperture and shutter to DIFFERENT settings but so that your light meter is still centered
- Take pic
- Adjust one more time.
- Take pic

A series of images demonstrating a focus bracket. The image on the left shows
a single shot taken at f/10 with the features of the fly closest to the camera.
The center image shows the features farthest from the camera.
The image on the right shows focus stacking: a sequence of six incrementally
focused images of the fly assembled to make a composite image using CombineZM.
